There were two sets, one with the GS-4 and 5 cars, and one with a diesel and 4 cars. The steam set sold for quite a bit more.
As you mentioned, they go for a premium these days. I'd like to put together a set with the Reading engine, since that's the one I worked on. I have the engine from Broadway Limited, and a couple of cars in storage, but not enough to really put together a good representation.
Last thing-as I recall, the AFT observation car, at the end of the train was a former Reading Company car, which would be about 73' long. Lionel's version was a full 85' car. Did the AFT extend the Reading car, or is the model inaccurate? I've wondered about this for several years since looking at old pictures of the train sitting in Morristown, NJ, where I saw it.
I was in 8th grade that Summer, and convinced my parents to take us to Denville Jct, to watch the train go by on its way to Morristown. It was listed in the Star Ledger of passing thru Denville, about 11:40PM. Needless to say, we got home much, much later the following morning.
