Working on the 2 End Loop Modules - Part 5

"Why O' Why?" am I going through this writing of turnout making? There are the older Atlas turnouts made 20+ years ago. These turnouts are easy to install. They have a 24" radius curve. BTW-It's easier to spiral inward than outward on curves especially involving turnouts.

My goal is to encourage those of you who don't desire to use Atlas turnouts or can't get them. One con about using the Atlas turnouts is the mechanism sticks out the side of them. The "real" prototype mechanisms like Caboose Industries ground turnouts look better and work just as well as the Atlas with the exception of the frog wiring for 2-rail. However, with trolleys and all wheels grounded there are no problems.

The annual Hoosier Traction Meet was held on the 1st weekend of this month, September. The annual Indianapolis O Scale Meet is usually on the 3rd weekend of September. This year, 2016, the Indie Meet is also the National O Scale Meet. If you have problems obtaining tools and parts these are the Meets to attend. There is also the annual March O Scale Meet held usually the weekend of St Patrick's Day, March 17, at a hotel about 2-3 miles from where I live.

These are some items required if you intend to lay your own track and turnouts.

Rail Bender
Before laying any rail, a rail curve maker commonly called a rail bender is needed. Unfortunately I'm unaware of any source of an O scale rail bender. If you do not have one you'll have to look for one to purchase or borrow from a friend.

Placing a curve in rail to be used in curves is helpful. The bender has 2 holes to mount it with screws on something solid. I used the side of a module on which to mount my bender. Allow sufficient room to move the rail back and forth!
The bolt sticking out of the side is to be able to move the center wheel in and out to vary the amount of bend in the rail. The back of the plate has nuts or something to  hold the wheels in place. The bender has to be installed with washers between the bottom of the plate and the top of the material on which the plate is mounted.

The 3 wheels on the bender have groves milled into them to hold the base of the rail, the center web of the rail, and the rail head. The bender seem to hold almost any size rail from code 100 to 148 without any problem. Although it looks like the wheels can be changed. All of my work has been with code 100 to 148.

Try to get the bend as close to the actual radius required. It's easy to change the radius as the rail is spiked into place. But, once a piece of rail which is not the correct radius has been spiked in place; it might move out of location just a little bit.

In the photos notice the short length of rail (about 1" or so) from the center wheel to the outside wheel. This 1" of rail does not get bent as needed. There's a slight kink in the bent rail where the center wheel was located. The kink is hard to see. I started marking the amount of rail to be cut off while the rail was in the bender.

The red arrow is the mark mentioned above. The rail in the blue ellipse is the amount to cut off after the bending is completed.

This is a photo showing the kink in the rail from the rail bender. The last portion of the rail has not been cut off. My finger is only holding the rail down, next to the spiked down rail of the curve. My finger is not making the kink. The red arrow points to where the kink is and the rail to be cut off.


Spikes
Spikes are required to attach the rail to the ties. I use a flat blade pliers to install the spikes. Special pliers are available but I don't like them. I have found the rail can be spiked on every other rail. Sometimes additional spikes are required at special places.


Over the years my collection of track spikes has increase. This is what was found in my stock -
  • Micro Spikes by Micro Engineering size 0.015" diameter x 5/32" length Too small for O scale. Small head makes then applicable where 4 spikes are definitely required for cosmetic reasons. They would have to be glued in place.
  • "HO" Gauge Spikes by All-Nation Hobby Shop size 0.028" diameter x 1/4" length Unfortunately All-Nation is no longer in business. While the diameter of these spikes are great, the length is a little too short for O scale. Nice to fill-in on stable track where more spikes are required to hold the rail.
  • "O" Gauge Spikes by All-Nation Hobby Shop size 0.028" diameter x 7/16 length 7/16" is just short of 1/2". Same info about All-Nation. The diameter of these spikes is great. The length if the spike may be too long for most applications. The length of the head of the spike may be longer than the base of the rail. When used the spike may force the rail out of alignment! They've been used when rail has to be forced into position and held in place. It's best to drill a pilot hole for these.
  • Old Pullman Spikes by Old Pullman size 0.035" diameter x 5/16" length Unfortunately Old Pullman is no longer in business. These spikes do show up for sale at O scale meets. These are perfect spikes to use. Most of the time they can be just pushed into the tie to hold the rail. The spike must be pushed in correctly of else the tie may split. Sometimes a pilot hole has to be drilled.
  • Code 70 Spikes by Unknown Manufacturer size 0.025" diameter x 11/32" length I have absolutely no idea where these spikes were obtained. They are great but easy to bend when being pushed into the tie and roadbed. They have a great application in making open roadbed track. This will be explained when this comes up. 
Whenever spikes are being used a battery operated Demel Tool is kept handy with a # 74 drill (0.0225" diameter) in the chuck to make a pilot hole if required.

Perhaps now is the time to mention the new cordless drill available from Dremel. It's their model 8050 Micro/Model:8050 https://www.dremel.com/en-us/Tools/Pages/ToolDetail.aspx?pid=8050#.V96bIYWcGM8  This is a light weight drill for as you may guess, light weight applications like drilling small holes. What's great about this drill is the lack of a cord. At the end of your work session place the drill back into it's holder/battery recharger.

Rail Laying
To start laying rail, for the traffic facing turnout a small section of flextrack was installed where the cork roadbed was started. This straight flextrack acted as a "gauge" of where the rail was to be laid for the start of the turnout.

NOTE - Each end module has 2 turnouts. If you'll recall it's been more than 10 years since I've scratch built a turnout. The building of the 1st turnout on the module was not as satisfactory as I had wanted. The 2nd turnout on this module turned out better. Therefore only the building of the 2nd turnout on the module will be shown.

In building a turnout install each piece of rail as recommended in the many YouTube videos on turnout building. After the straight stock rail was installed, the curved stock rail was installed. The curved stock rail was longer than required. This will be explained later. Work was stopped on this turnout.

Attention is now given to the trailing turnout and the crossing next to it. Install pieces of flextrack on both sides of this turnout to act as "gauges" for the location of the turnout rails. 
The flextrack is on the right of the turnout. Rail joiners are installed at the end of the rail to hold the stock rails of the turnout in place. You may notice the small brads (nails with small heads) holding the flextrack. Holes have to be drilled in the plastic ties for the brads.

Install the straight stock rail. Then install the curved stock rail using a 36" long piece of rail (with the ends cut off from the bending process). This rail when installed will be part of the curved crossing rail. Continue to spike this piece of rail in place using your trammel as a guide. Add another piece of curved rail to this one and spike it in place. This interior curved rail is spiked to the location where the curve reverses.
Green Arrow = Hole for the 14" curve through which the rail is viewed.
Blue Ellipse = Spike pliers I don't like; they lock the spike in to hold it.
Red Ellipse = the pliers I like to drive spikes.
Dark Blue Ellipse = Code 70 and Old Pullman spikes.
Pink Ellipse = NMRA track gauges always ready to be used.
Dark Lime Ellipse = Center of trammel held at correct height as rail head.
Important Note: The curved rail goes all the way through the curved crossing as 1 piece of rail!

The point of where the curve reverses is determined by drawing a line between the 2 centers of the curves. The line drawn between the 2 center points may be on an angle but don't worry.
The pencil line can be seen on both sides of the cork roadbed. Also note the slight "S" shape of the roadbed.

The next piece of rail to install is the curved piece which will be part of the frog. The next Post will start off with installation.

Cheers,
Ed

Working on the 2 End Loop Modules - Part 4

Once all the cork work is completed for a module, photocopies of the turnouts to be installed or scratch-built were glued over the cork.
An actual premade turnout was placed on my printer/photocopier. An original photocopy was made. On the original photocopy the location of ties was marked and darkened. Other notable landmarks were added. Notice the arrows where the center point of the track is located. Then copies of the original photocopy were made to glue to the roadbed.

The photocopy is glued onto the cork using the center point locations on the center line of the cork. A piece of plain white paper was glued where the crossing will be installed. This was done to mark the center locations of the crossing plus the location of any rail. The green ellipse is the location of the ground throw for the turnout. Read the engineering and operation material at the bottom of this Post.

The premade #3 frog turnout was not used on the layout. Instead it is used as a sample of the parts to be made. Masurements can be obtained from the premade turnout.

Now actual wooden ties can be glued in place. To match the plastic ties found on Micro Engineering's code 125 flextrack,  7" x 9" x 9'0"  prototype O scale wooden ties available from Right-O-Way (R-O-W) were used. The center point of a bunch of wooden ties was marked in pencil. Then using wood glue the ties are attached to the cork road bed. A heavy weight was placed on the ties until they dried.


The weight weighs about 1 lb. It's a cut-off from a piece of round steel. My son had painted it black. The steel rule helps to spread out the weight. Almost anything cam be used for a weight. As you may have guessed, not too many ties were glued down at a time.

An irregular pattern to how the ties were laid can be seen. Ties may have been laid by different crews at different times. Who knows?

Once all the required ties are glued in place, the location of the rails are penciled in. The location of the rail is just to get an idea as to where the rail will be when finished. BTW - When the ties are glued in no specified pattern is followed. Although some attention is paid to the center line on the ties and the cork roadbed, some ties may be crooked or toward one side or the other. Remember, the C&U is a late 1940's to early 1950's heavily used streetcar line. They didn't have the track building, replacement, or reconditioning equipment available today.

The ties glued in place include those for the 2 #3 turnouts. R-O-W 7" x 9" x 16'6" switch ties were used. Shorter ties were cut from 16'6" ties. For a #3 turnout this bill of ties was used:
# of Ties      Length in Feet Prototype Measurement
     3                         9'0" (normal length ties)
     2                         9'6"
     2                       10'0"
     1                       10'6"
     1                       11'0"
     1                       11'6"
     1                       12'0"
     1                       13'0"
     1                       13'6"
     1                       14'0"
     1                       15'0"
     1                       15'6"  
     3                       16'6"


The 2 long ties which will hold the ground throw were glued in place 1st. The 2 pieces of wood at the top and bottom are to space the ties. It's important for the rodding from the switch points to the ground throw mechanism be able to move and not rub on the switch ties. The top and bottom pieces of wood will be removed once the glue on the long switch ties dries.

There were some ties which were longer than the ties available from R-O-W. For these basswood 5/32" x 3/16" was used. This happen mainly in the area of the crossing of the west bound mainline.

There's one extremely important item regarding turnouts and track crossings and their frogs. The standard rule of thumb is to have a tie or ties immediately under the point of the frog. This part of the frog takes a terrible beating by the wheels passing over them. The wheels fall into the gap of the frog. Some railways have placed material into the space between the rail and the wings (flange way) to support the flange of the wheel. This aleviates some of the problem. 



This photo has several items to point out.
Red Circle = a short section of premade flextrack to be used to gauge the rails.
Gold Circle = a 3 point track gauge for code 125 rail made by Precision Scale.
Green Circle = NMRA O scale track gauge.
Blue Circle = an old 3 point track gauge made by Walthers about 50+ years ago.
Yellow Boxes = potential locations of turnout points and crossing points.
Dark Lime Box = extremely long ties for ground throw explained below.
Pink Box = a plier used to install spikes. I didn't like it.

The 3-point track gauge for code 125 rail made by Precision Scale Company is hard to find. You would do best by looking this gauge up on the PSC web site for the stock number. Then order 2-3 of them. PSC turn around time is about 2 weeks. My recommendation to order 2 or 3 of them is to cover any which may be lost or misplaced. You'll find you need 2 any way to keep the rail in place and gauge as the rail is spiked down.

The older 3-point track gauge distributed by Walthers was for code 172 rail which had a wider rail head. The code 125 rail slides from side to side in the gauge.

The NMRA gauges are the final inspection tool required to check your work. 

The yellow boxes are the extra ties which were placed where the points of the turnout frog and crossing points may be located.

Before going further some engineering and operation of the return loop is required. The C&U is a heavily used streetcar line. The passenger traffic from the east terminal to the Zoo and back is heavy during the later spring, summer, and early fall. During this time of the year many runs are turned back after the Zoo passengers depart the car and enter the Zoo. Other times of the year cars run from the west border of Chicago, the eastern terminal, to Utopia, the western terminal. During the warmer months of the year only 1 in 3 or 4 cars operate from Chicago to Utopia. The balance of the cars run only to the Zoo and back.

This means during the summer months, the Zoo loop has to be operated by a switchman located at the loop. The 2 turnouts are hand thrown. Caboose Industries ground throws were used. The switchman has to not only control the 2 turnouts, he must keep track of cars coming east from Utopia, and perhaps have "orders" telephoned to him.

For convience both trunout ground throws are located on the same side of the 2-track ROW. One of the turnouts will have longer than normal ties for the ground throw to be installed on. The C&U will construct a wooden walkway for the switchman to walk between the 2 ground throws. To keep the switchman out of the weather (sun shade on a hot day) a wooden shack to include a stool, small stove, and telephone will be constructed when the module is finished.

One other item about the end loop modules - the modules could have been constructed with passing sidings. Passing sidings were not included for 2 reasons. The inclusion of a passing siding would have increased the size of the module. Since I've not constructed any modules before, I think it would have increased the size. The other reason is, it's been about 43-44 years since I've constructed any street track and 12-13 years since constructing any open track. I did not want to make the scratch built track any more conplex than necessary.

Ed

Soldering and Working on the 2 End Loop Modules - Part 3

Eventually soldering will be required for the trackwork and electrical parts of the new layout. This Post is about the main tool used in soldering plus some general thoughts about "how" soldering or for that matter how many glues work.

When work was started on the 2 end loops I had 2 60-watt soldering irons. One of the 60-watt irons was purchased from Radio Shack eons ago. The solid copper tip had been lost. The 2 screws could no longer be tightened enough to hold the tip in place.

A second 60-watt iron was purchased. But it was nothing like the older 60-watt iron. It was too light. It was easy to "burn" the solder on the tip if left plugged in to long. I wasn't pleased.

Soldering works when there is enough "heat" to melt the solder to the parts being joined together. There's enough written material plus, I'm sure, YouTube videos explaining how to solder.

One comment about soldering guns. The tip is heated with electric current passing through the metal tip. If all the connections are not 100% correct, less than full current will pass through the tip causing it to heat up less.

Forty-eight years ago I purchased a 240-watt American Beauty soldering iron. Several brass models were assembled by me using this iron. I still have this soldering iron. The company American Beauty makes soldering irons plus other soldering products which are correctly named. They are "beauties"! My 240-watt iron is used from time to time. However, it's for heavy duty soldering.

For the soldering needed for making the track work for my modules, a 60-watt iron is sufficient. An American Beauty 60-Watt, 1/4" Heavy-Duty Soldering Iron Model 3125-60 was purchased for under $100.00 including shipping. It works great on all types of track I've worked on thus far.

Just in case you may be wondering, over the past 50+ years of model making I have used the following to solder -
10-watt irons,
15-watt irons,
60-watt irons,
100-watt soldering guns,
240-watt irons,
propane torchs,
jewel's oxy/acetylene torch,
resistance soldering, and
there's probably some I've missed.

Plus, I've used solders with different % compositions of metal.

The 60-watt soldering iron I've recommend; should be left plugged in only as long as you are actually soldering. If this turns out to be a long time keep checking the tip to see if the solder is starting to oxidize due to the heat. Oxidized solder will have a white chalky look. At this time the tip is too hot and the iron must be unplugged.

If plugging and unplugging the soldering iron is a problem for you, get an on-off electric foot pedel to place in the electric line. All the ones I've owned require the operator to keep their foot on the pedel to keep the electricity on. American Beauty sells one plus they are available through Amazon.com.


OR, as long as you're looking at the American Beauty web site, look at their Model V36GL3 60-watt Industrial Grade Soldering Station. If you're planning on using soldering for work requiring a long time period to finish, a soldering station is what you need.

The other part of the Post is in regards to cleaning up the soldering once completed. Use files, wet/dry abrasive  papers, wire wheels, etc. In cleaning up the joint, DO NOT REMOVE ALL OF THE SOLDER!. Some solder must remain on or in the joint.

It's the solder keeping the 2 or more pieces of metal together. If you solder a piece with a post which goes into the metal, drill the hole for the post slightly larger than the diameter of the post. The same holds true for almost all glues no matter what they are. The plastic solvents used to build models are not the same as a glue.

If possible "tin" the pieces of metal to be soldered prior to soldering them together. Again, there's enough written material plus, I'm sure, YouTube videos explaining how to solder. Either read or view the material.

Cheers,
Ed

Working on the 2 End Loop Modules - Part 2

The 2 end modules were assembled together for the installation of track, overhead wire, and electrical gear. There are at least 2 different sets of instructional videos on the building of O scale track including turnouts on YouTube. For this reason I will not be spending much time on this. Instead unusual items will be mentioned.

The open track module will be worked on 1st. This is the farthest west module of the layout called the  "Zoo Return Loop". It's been about 15 years since I last built track and turnouts. I wanted to built the trailing turnout before tackling the traffic facing turnout.

As much as possible straight track was to be flex-track. From experience I knew bending flex track around a 14" radius loop would be hard to do. This loop would require handlaid track.

I knew when the cork roadbed would be laid, the centerline and rail lines would be obscured. But, I have an answer for this which will be covered as the track is laid..

The other item before I forget, I've always built turnouts in place. I don't like to prebuild the turnout and then transfer it to the location where it is to be used.

Also, you'll notice although cork roadbed is used, the cork for turnouts is not used. The regular cork roadbed is used through out the layout. This is because the retention of the  pencil (ballpoint) drawn midline of the track is important to retain.

Lastly, always install the curve(s) 1st and keep them intact as other parts (cork roadbed, rail, etc.) are installed. You'll see this with the cork roadbed and then any ties and rail later.

Those who saw my layout on the 2nd floor of the garage will remember the cork roadbed was doubled-up - one layer upon the other. The prototype for that layout was a mainline railroad where the actual track was often 12 inches or more above grade. The prototype for this layout is a trolley - streetcar line.

Starting at the connection of the 2 modules, glue and tack in place 1 of the 2 cork strips necessary for the west bound track . Keep the center flat faced part of the cork strip on the centerline.

Follow the centerline through the facing turnout and around the the loop. At the ends of the cork strip use 2  tacks or small nails.  Continue gluing and tacking the 1 piece of cork roadbed  around the loop through where the crossing and trailing turnouts are to be located. Continue on the east bound portion of the track back to where the 2 modules connect.
The pliers with the green handles are special. Notice the cutout portion of the tips. These pliers are to be used to hold small nails, brads, etc. during nailing.

When this is done install the pieces of cork making up the 2nd half of the roadbed. Now the balance of the roadbed can be installed. A sharp razor blade will help to cut the cork as needed. The centerline of all the curves and loops can be seen as well as all of the straight track!

Glue in any required filler material. Allow the glue to dry prior to starting the next part.

Ed

Working on the 2 End Loop Modules - Part 1

If you've read the info on the EPTC web site regarding their modules and/or if you've seen the modules in action, you are aware of the built-in control of models operating on the modules. Through simple model detection electrical circuitry sections of track can be turned off in back of a model. Models will stop and start on their own.

At the last EPTC Meet the 2 models I brought to operate on the modules had problems. They were set up for pole reverse plus the ability to operate on 2-rail. This meant the track detection system used in the EPTC modules placed an additional electrical current through the motors.

To be able to operate all of my models on my new layout, the EPTC model detection system of operation cannot be used. I'll have to come up with some other simple plan. As for now a 1 or 2 operator plan will have to do for now.

The other item which came up is the number of different profiles there were for the code 125 rail I had left from prior layouts. My collection of code 125 rail goes back to the early 1970's. There were perhaps 5 or 6 different widths of the head, web, and/or base of the rail. However, the height of the rail was always 0.125".

The rail with the widest head and base was reserved for the modules with tract in the street. Some of this rail looks like it's steel. It looks like it has rust.

My son helped with the assembly of the 2 end modules. Actually, he built the 2 end modules with dad's (my) assistance! It was something to watch him work. I was proud he is my son. He had worked as a finishing carpenter plus he built cabinets from plans unique to the area into which they would be installed. Since much of the work was done in the Frank Lloyd Wright homes in Oak Park and River Forest, IL; his work was spot on!

Here's the room for the new layout prior to any work being started.

These are the modules assembled into a layout prior to the addidion of the track. The legs are 3/4" plywood 16" x 36" high. EPTC shows how the center of the leg pieces can be cut out to reduce weight. We plan to work on the legs later.
The modules are at different heights due to the difference in how the track will be built. The module on the right is the open track built on a cork roadbed with prototypical ties. The module on the left will have the rail installed on thinner "brass" ties. The rail has to match-up at the joint of the modules.

In the photos the location of the track can be seen. The center line plus the location of the 2 rails are included.

To draw the radius for the loop a large trammel was made from a piece of basswood 1/4" x 3/4". Holes were drilled for a nail and for a pencil to fit through. The holes for the pencil were at the midpoint of the radius. Two additional holes were drilled 5/8" from the center point of the track. This is where the rail are to be located.


In the top photo 6 holes for a pencil are shown. One set of 3 holes is for a 13" radius while the other 3 holes are for a 14" radius. The holes are labeled for identification. The bottom photo shows the nail used as the center point. If you look carefully the hole in the module top can be seen.

After seeing the modules and the space available around the loops. I decided to increase the radius of the loop from 13" to 14". Information from Old Pullman, now out of business, stated #3 frogs turnouts had a radius of 15".

The 14" radius will make it easier to fit the #3 frog turnout together. Plus, the increased radius will allow more models to operate around the loops.

This is a drawing of the trailing #3 turnout plus the crossing to bring the cars back on the opposite track. The dark mark in the upper left corner is what remains from a staple used to assemble the module after it was cut off with a cut-off wheel. My son used staples instead of nails.

Ed

Paul J. Mayer (Shoreline Decals) 1935 - 2016

Paul Mayer the owner of Shoreline Decals passed away. Many of you, especially if you modeled in HO, may have obtained decals for your trolleys from Paul over the years.

Paul was great. For the decals he did not have ready made for sale, if  you could give him either art-work, photos, and/or dimensions of the decals, he would either make the decals himself or have them made for you. He was not able to make decals in either gold or silver.

Paul's latest venture was an HO model of a 3-D printed CSL Sedan. It was a beautiful model.

Outside of the business end of the hobby, Paul was a congenial, friendly fellow with a sharp sense of humor. He was always a joy with which to have a conversation.

I was especially pleased to have long discussions with him regarding the business side of the trolley modeling hobby. He was always spot on with his observations and comments.

As an O scale trolley modeler in need of decals for my models, he was a fantastic resource. Without his decals most of my models would remain unfinished. I sure the same can be said of many trolley modelers in the Midwest and perhaps in other places.

Paul, from all your friends in Chicago, Thank You and may all the lights be green!

Sincerely,
Ed

Starting the Next Chicago and Utopia Layout

There were a few items left over from building my prior layout. These included flex track with code 148 and 125 rail, rail joiners, pre-cut ties, rail, brass rods for line poles, plus other items.

Two sets of items I have, unrelated to the prior layout, included a pair of right and left hand Right-O-Way street turnout point and mate sets and some right hand #3 frog code 125 and code 100 turnouts. The #3 frog turnouts appeared to be made by Old Pullman.

Furthermore, the #3 frog turnouts had been purchased on EBay as a lark - never can tell when you might need them - 2 or more years ago. The point I'm trying to make is this was well before any talk about downsizing came up.

The above mentioned items have come up because they have played a part in my planning for a new layout. Thus far a decision has been made to make a modular layout. The "base" module will be 48" x 16" with the ability to alter the size as required.

The track plan is to be a "U" shaped dog bone for streetcars and small trolleys. Other shaped were considered. However, the amount of space is limited.

To make the layout operational as soon as possible, the end loops of the track plan are to be made 1st. Information available from the East Penn Traction Club (EPTC) on the web was downloaded. This material was read several times.

The basic design of the EPTC as to having double tracks on the module was adopted. The loops had to be 14" radius. Some of my models had a tough time making it around the 13" radius on my test layout.

Scale drawings were made of the what could be the end loop modules. Larger and larger scale drawings were made. From the drawings it started to look like the end modules would end up being 4'6" x 3'6".

Next was to see what the total layout made up of modules would look like. That is, how many modules would be required to make the "U" to fit within the confines of the main, large room in the basement of our townhouse.

Since the layout was to be made up of modules, the size of the 2 modules which were to contain the 90 degree curves had to be known. Before any designing was done, how well would the track diagram of the Chicago West Towns' (CWT) La Grange Line fit into what I wanted.

In order not to repeat material presented in a prior Post, be sure to read my Post "What Factors Have Influenced My New Layout Decisions?" dated July 1, 2016.

One arm of the "U" shape is shorter than the other arm. Unfortunately the shorter arm was not the one I wanted. The layout would be in the opposite directed from what I wanted. With time this will make sense to you.

Another thought to take into account is I have a few "streetcar" models, plus some interurban and "L" models. These will require a method to reverse then at the ends of the layout plus curves at the 90 degree modules with a radius greater than 13". I picked an 18" radius for interurban and "L" cars coupled together.

For my friends with streetcar, interurban, and "L" models the greater radius will work out well. As for being able to reverse the models at the ends of the layout. The same method of reversing prototype cars on a double track route will be used. A facing crossover made from a pair of right hand turnouts will be used.  Almost all of the straight track modules could have a facing crossover. This style of crossover would be trailing for right hand operation.

That solved, back to the size of the 90 degree module. From scale drawings, the size of the module could be a small as 36" x 36". After rechecking the floor space available, it looks like the balance of the modules could be 48" long.

This drawing shows the modules which can fit into my available space. The modules are labeled with CWT La Grange Line locations. Not all of the importation locations could be fitted in. I picked the ones which could be made by me within a reasonable time. The width of each straight module needs to be determined.

The La Grange Line locations chosen are:
22nd & Kenton (east terminal) - paved track (my module faces east and not west)
22nd St. - open or paved center track in wide street
22nd & Harlem curve - paved track intersection with the single track to the "Siberian" barn
Harlem Ave. - open track in the center of the street
Harlem & 26th St curve - open track which did not really turn into 26th St.
Parkway Jct. - open track interchange with the IC (more on this in a future Post)
1St. Ave. - open track/paved crossing of 1st Ave.
Brookfield - paved track at south entrance to the Brookfield Zoo
Turn back - open track crossover turn back immediately west of the Zoo
Barn (possible module) - paved street to the "Siberian" barn for visitors' model(s) storage


There's more coming! Cheers,
