Lionel Trains Operating Dispatching Board No. 334The Operating Dispatching Board No. 334 was catalogued from 1957 until 1960. It was not a big seller and this fact makes this accessory hard to find today.
spacer
Most likely Lionel made this dispatching board in 1957 and it took an additional three years for dealers to sell the existing stock on hand. This is supported by the fact that there are no known variations.
spacer
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.
spacer
The correct voltage is absolutely necessary for the proper operation of the dispatch board. The only instruction sheet that was issued, No. 334-86 dated 9-57, calls for 10 to 14 volts. A voltage that exceeds this amount would cause a vibration and could dislocate the drive belt. We recommend that you use a variable voltage to set the voltage for optimum operation.

No. 334-67 Parts Envelope

The instruction sheet was contained in parts envelope No. 334-67 that is illustrated above and to the right.
spacer
According to the instruction sheet the dispatch board was always lighted by 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.
spacer
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.
spacer
The dispatch board has a TAN plastic base that has three electrical binding posts, and the clock on top is illuminated by the interior lights. The board itself has a special coating that would allow arrivals and departures to be chalked in the green areas that are located on both sides of the center displayed data.

Dimensions: 9-7/8 inches long, 4-1/8 inches wide, and 7-1/2 inches high.
