Westchester Junction Part 1

After receiving a number of positive comments about signaling on my layout, I made an executive decision to replace the newly installed single head signal for east bound trains at Westchester Junction with a new home interlocking signal with 2 heads on the mast. The upper head (red and green aspects) is for the track ahead while the lower head (red and green aspects), normally for a diverting route, is for the condition of the junction. 

Another way of saying "condition of the junction" is the red or green aspects will tell if the track turnout is set for through (green) or diverted (red) traffic.

This brings up some interesting set of potential aspect configurations. But before getting into the configurations, here's the installation of the signal.

This is the new signal base held in place using a generic clear "DAP Kiwik Seal". The material comes out white and cures clear.

A machinist square is used to "square-up" the signal mast.
A view down the tracks. The mast leans a little from the tracks. NMRA Clearance Standards are followed for the placement of the signal.

The next morning the adhesive is curing. More adhesive was used than required.
Even though the adhesive has not completely cured, the area is re-ballasted.
The name of the junction is placed on the building. The name was prepared on a computed for the desired size. After being "glued" onto a 0.010" thick of styrene using the clear generic DAP adhesive caulk, the name was covered with clear adhesive tape. The sign was cut out with a razor blade then attached to the building using the caulk.
Here is an over view of the new junction looking east bound with its signals in place.
You may have noticed the 2 electrical heads on the junction building. One pair is for the company telephone while the other pair is for 120 v electricity. The junction building will be receiving telephone and electrical service from the Westchester station.
We'll cover the various light configurations in the next post.
