Jerry, Maybe I didn't make myself clear. The block occupancy/detection circuitry is all in place. What we are having a hard time locating are type D signal stands.
Details West -out of stock, no ETA.
Walthers Kato - look like they belong on a 1950's Lionel layout.
These are avail on the bay:
But the LED's are setup like a traffic light.
Any help will be greatly appreciated.
