The American Flyer Warning Bell is a ringing bell and light for a highway crossing warning device to visually and aurally alert motorists and pedestrians of an approaching train.

The American Flyer Warning Bell is 9" high, making it a 1:48 scale model of a 36' high signal.

The American Flyer Warning Bell has a diecast base and a formed sheet metal post. The sign is painted. The bells and mechanism cover are plated.

Electrical connections are made to two binding posts on either side of the bell mechanism.

An adjustment screw on the left side of the mechanism can be used to change the sound produced.

The American Flyer Warning Bell can be operated with Three-Rail Innovations' Two Relay Controller .

An isolated rail track block is constructed positioned so that the accessory is activated before the train reaches the highway and stops after the train has passed the intersection.

The 2RC features of OFF/ON, Limited, Slow Flash, Relay-On-One-Time, Short-Time-On, Crossbuck, and Slow Crossbuck can be used.

The electrical coil can overheat, so some operating time limitation is prudent.

The wire lead for the light is connected to the right terminal post. It can be removed and connected to a different 2RC relay and operated separately from the bell mechanism. A flashing feature is appropriate.
