they work but kinda weird issue any suggestions alittle info 3 blocks 3 signals the first one is is by the bridge second one is by the tunnel and the third is by the other tunnel. 3 relays a dpdt a spst and another that 2 #87 pins no a and B it seems tho the green is setup to be constant until another light is turned on then the green turns off.
I have several signal blocks on my layout. Some of my relays are Radio Shack relays and also some Potter + Brumfield relays. I have a 1000uF capacitor wired up to the contacts for the relay coil. The capacitor keeps the relay coil from chattering. So when the train enters the block it holds the signal at red until the train has left the block. My signal circuit is a simple red / green , no yellow approach aspect.
Here is a drawing of my block wiring. most of my signals are scratch built with LED lamps, not the 153 shown in my drawing. So the lamp power is DC with resistors in line with the LEDs on the signals.
