Excuse me if this is old news, but I ran across something that might be interesting.
Not rarely, one has trouble finding parts lists and diagrams on the Lionel web site. I today saw an ad for a 6-28065 command upgradeable Hudson, but a search for parts turned up nothing. Indeed, a few years ago there were a few threads here with questions about that exact engine. I then searched by the road name and number (NYC 5412) and found that loco as part of a set, 6-21988. Lo and behold, searching replacement parts for the set showed the engine and tender, each with a complete parts breakdown!
I just posted a partial breakdown here to prove a point. Same thing appears to work for the RTR stuff, the popular 7795 0-8-0 has no parts listing of its own, but as part of set 6-30103 you can see the whole thing.
If you knew all that, sorry to bore you, but it was news to me!
