No. 99 auto block signal

The ITAD would act as the insulated outside track. You would need an isolated center rail hooked to the white wire to control stopping of the train.

Thanks for helping. I do not want to start and stop the train. I would like to have the lights change when the train goes by. Not sure how to hook it up to do this. I was trying to get it to work but could not come up with the right wire combination.
I would like to use an itad to do this.
Thanks...Steve

Do not make the block with the center rail or hook up the white wire and the train will not stop. As I said the ITAD will replace the insulated outside rail.

Hook the red and black to hot and common and touch the yellow to common and see what happens. It will not work as a block signal but can be faked.

I wish you could buy this as block signal with different electronics to make it work the way I would like it.

Thanks for your help. I got it to work but the timer in the signal took too long to change back. It stayed red most of the time. Could not get the yellow light to work.

Thanks...Steve

It might stay yellow in continious operation or go green to yellow.

You would have to modify the internal wiring so you could hook up the lamp leads directly to the controller your using to switch which lamp is on. Originally the thermal strip defaulted to contacting the green lamp lead so it showed when cool. When a train entered the block and stopped the power was bypassed through the element inside the signal and started heating the thermal strip. The red lamp was grounded as soon as the train entered the insulated section. As the thermal strip heated it turned the yellow lamp on and the train proceeded. After the thermal strip cooled the green lamp was again lit and the cycle started over again. You would have to find the hot leads to the three lamps and disconnect them from the thermal control inside and hook them to your ITAD directly and set the delay on the ITAD to your liking.

Thank you very much. Not sure if I want to modify or take it back. I do like the looks of it.

Isn't there a switch somewhere on this signal that allows a person to adjust the length of delay or stoppage of the train. This would mean the light would not stay red as long, and would be more brief. I could be wrong, I just do not remember.

Yes there is a knob on the back but I have it set as short as it goes and it is still too long.
