A Banjo Signal is a highway crossing warning device to alert motorists and pedestrians of an approaching train. When a train is present, the red light is on and the wig-wag arm swings, passing in front of the light so it appears to flash.

The Lionel 140 Banjo Signal was introduced in 1954.

It is 8" high, making it a 1:48 scale model of a 32' high signal. While a bit tall for O Gauge, it serves well for a toy train layout: the swinging arm and flashing red light get attention.

The base and post (up to the horizontal arm) are diecast metal painted black. The top of the post, crossed arms, wig-wag, and bulb cover are black plastic with white lettering.

A red bayonet bulb (L53R) is used. (Click number for bulb specifications.)

A 145C weighted contactor came with the 140 Banjo Signal. Recommended operating power is 12-16 volts, AC: a little adjustment is usually needed for best operation.

The Banjo Signal can also be operated with an insulated outside track rail. Make an isolated rail from one or more track sections so the Banjo Signal operates as a train approaches the highway crossing.

The 140 Banjo Signal can also be operated with Three-Rail Innovations' Two Relay Controller . You can accurately control where on the track a moving train will cause the wig-wag arm to start and stop and activate other highway crossing signals from all or part of the same isolated track section.
