I have a few 153 block signals and i forget how they wire up. anyone know how they wire up? And, am i correct on this, everytime the train puts pressure on the contactor the light would change colors, is that correct? its been a while since i used them. they wire up like gateman or switch tower?? thanks.
Here’s the solution for the 145c contactor: http://www.thortrains.net/manual9.htm
If you want to get fancy and do away with the contactor: http://cs.trains.com/forums/1017074/ShowPost.aspx
Also, do a search on 153 block signal, and you’ll get a few more options.
