File:Marx Block Control Twin Train Sets

Description
Marx Block Control Twin Train Sets. The set running here is as it came with the block signal/controller, accessories and track. Best I can tell, the set is missing a couple of billboards and one of the green streetlamps. To make the blocks, it comes with 3 "special track sections". These are a normal straight piece with no center rail pin on one end. That rail is also shortened about 1/8 inch to make sure there is no contact with the next track section. The signal has an adjustable rheostat in it to help control speed.
