This was another one of those accessories, like the No. 128, that would use a vibrating coil and a pinion and worm gear to move the DARK BLUE attendant across the board and cause the information in the lighted slots to change. This action would occur when a No. 90 Controller button was pushed. At the end of the attendant’s movement the worm gear would turn the attendant 180 degrees to be ready for the next operation.

According to the instruction sheet the dispatch board was always lighted by a L53 or L63 bulbs. However, the Lionel Service Manual calls for an L57 lamp. All of these are bayonet mounted clear bulbs, but the L57 draws 0.1 amps, and the others draw 0.2 amps, so they give a brighter illumination and release more heat. We would recommend the use of the new LED clear lamps that generate no heat be used on this accessory. The lamps can be changed by unscrewing the two top ornamental horns on top and lifting off the cover.
