Integrated Signal Systems’ mission is to provide prototypically correct O signals and the electronic controls to simulate an ABS system. We manufacture a variety of rugged brass O scale block signals, either assembled or partially assembled kits to your specifications. We also manufacture and separately sell the electrical/electronic components to detect the presence of a train and correctly operate the LED lamps in the signal heads and on the panel boards. We also have dimensional data for signals used on most North American railroads. The kits cost less, but we drill the holes, solder on the mounting brackets and platforms, so all you do is install the base, the ladder and handrails.
