This is the first I am hearing about this. Just like how the first time I heard about the Train of Tomorrow was a couple of months ago before I promptly ordered it.
So it looks like these trucks held different payloads? Some even had a full car on display underneath? How neat.
Does anyone have a good source of a scale model of these things? They would look great next to the ToT. Man do I love everything about both of these. Not only the art-deco design but just the excitement of what demonstrations like this and the World Fair represented. So much optimism and excitement about the the possibility of the future. I love this stuff.
Here is a video about it that shows the beauty of one of the remaining trucks in detail. http://www.washingtonpost.com/...d06ca77f1_video.html
