With arrivals of the 3rd Rail Train of Tomorrow occurring, a video (aka "newsreel") of the prototype T of T is well-worth a look:

Frankly, before all of the hoopla about the model T of T, I had no idea it was, in fact, a REAL train.
Here is another link to information, including period photos and color images of the T of T. Among the facts, the T of T was merely a scale model produced by GM as a sales and marketing tool before WWII. In 1944, the decision was made to make a real train and Pullman was contracted to do so. Enjoy.
