Description

PDF

HO scale model of North American color light signals. This is a model of the modern design that is becoming more common as it replaces older versions. The model is designed to be resin printed due to the size of pieces. 2, 3, and 4 aspect heads are included. Parts also require a 3/32" (2.4mm) brass tube to support the parts and run wires through the tube. You will need to slot the tube to feed wires into. If you want to mount the signals on top of an equipment box see the model page here.
