I recently purchased a 4 car Blue Comet set & 5 car State Set for $800. I'll be keeping the Blue Comet set and the add on Maryland car from the state set and selling the other 4 cars. I now have all the State Cars and can make a full 14' long 6 car train! I'm excited to run it on the 4th.
Id post a pic of the Blue Comet set, but I don't have a locomotive for it currently. I think I'm going to find a black 392e at some point to pull it, I figure at Christmas time it'll look kinda like the Polar Express.
