Rutherford West - Interlocking Signal Bridge Operating...

So today I completed the wiring and programming of the Rutherford West - Interlocking Signal Bridge.

The process is fairly simple to get these wired to the Digitrax SE8C's.  The connection between the signal heads and the SE8C is made via a Digitrax TSMK (Terminal Strip Mounting Kit) and a 10 pair printer ribbon cable.

The TSMK makes hooking up the physical LED wires easy, and they also include inbuilt resistors too.  Two (2) TSMK's are required for one triple head mast, and a single TSMK for a double head mast/dwarf.

The T, M, B in the photo below is reference for Top, Middle, Bottom...


One of the issues I often face when performing this task is the inability to see which signal aspect is on when underneath the layout connecting the wires to the TSMK.  This signal bridge wasn't that bad as the bench work is only 250mm (10") wide so I could actually see them from underneath.

I have for some time been looking for an app to utilise that uses a spare iPhone and the layouts WiFi modem to "stream" the images of the signal heads.  Today I was using an app called "Web of Cam" this app is perfect and also allows not only viewing from an iPhone & iPad but also from a desktop PC.


This makes programming the individual heads in Panel Pro and the masts a lot easier, no more backward and forwards trips from the Dispatcher's nook to the signal bridge on the layout.


The final colour of the aspects has changed a little with them going through the resistors that are mounted on the TSMK boards, I'm now really happy with the red, yellow & green.
