The first operational signal on the JL&T...

So last night I decided to install the first double head dwarf signal onto the layout, this one is a Tomar H876bl and is fitted with RRCirKits Tri-Colored LED's.

The area on the layout is based around Reading PA, and feeds back into Lancaster Junction (through the backdrop) so the signal is dispatcher controlled only.



Above a slow clear is being shown leading to Lancaster Junction...

The RRCirKits LED's are being run through 2K ohm resistors and they will likely be increased as they are still extremely bright.




As can be seen they are quite bright even 2' away...


To test the brightness and color of the LED's I made up a small device so the each aspect (top & bottom) can be checked against the other.  To date the red & green are getting 2K resistors (likely to be increased) and the yellow is using a 820ohm resistor.



The black substance is liquid electrical tape so that I do not inadvertently short out one LED's while testing each one.


Next phase will be to place the signal in Panel Pro, connect it to the SE8C ribbon wire and board, and test out its functionality.
