The Quick-Block Signal Control Board is what connects the signals to the block and controls the aspect of the signal. Each Block can have 2, 3 or 4 signals, and one board is needed for each signal head. (ie a block with 4 signal heads would need 4 control boards). Each shipment of boards comes with instructions and links to Youtube videos showing how to set them up.

Please choose either 2 or 3 aspect boards below. “Aspect” is the number of signal indications the signal can show, not always the number of lights on the signal. For instance, a signal with only a red or green light is a 2 aspect signal. One with a red, yellow and green is a 3 aspect signal, however PRR or B&O style position light signals may have multiple lights for each aspect. Drop us a line if you have questions!
