I have a reproduction of the MTC crossing signal used on amusement park trains. Stands about 6 foot tall and is mostly cast alum(originals were heavy cast iron!), flashing lights on both side, ringing bell that can be turned off. Plugs into any 120volt outlet. Can be carried around in one/two hands easily, so portable as well. Must be picked up in Kokomo, IN. Asking $895.
