Note that the large drum shaped top has mysteriously disappeared. Since it was made of bending ply & a wood frame, topped with hardwood plywood and Formica, this top was both cumbersome and heavy. So, a storage spot was needed when the table railroad was in operation. And two people were probably required to get the railroad into operation.
Also note that Mr. Westcott is operating the railroad from a small control panel. The panel looks like a Walthers Marnold® unit; these were state-of-the-art in the 1950â€™s, but were beginning to look a little long in the tooth by the late 1960â€™s. By that time, MRC was issuing transistor power packs that offered better control. Note, too, that the Marnold control panel is connected to the railroad by a substantial cable. Each turnout, track block and the turntable would require wires for controlling their operation. Today, of course, DCC makes this matter considerably simpler.
In the end, you have to wonder if this idea from the fertile minds of Westcott and Baron ever got built, but it certainly was food for thought.
