I've done several Pre/Postwar Lionel steamers. 1666 that looked like it spent time in a wet basement. A Marx 999 that had been played with to the point that a lot of paint was gone. Now I'm working on a 2026 I recently got off the bay. Picked all these up pretty cheap, and some time and TLC, scrounging parts off the bay and junkboxes is really fun. A few years ago I picked up four Prewar 1600 series passenger cars for $1 each. Three still had good paint, just needed roofs and a few trucks to be put back in service. The fourth had suffered from a really bad paintjob, and was made into my version of a 442 Diner.
I also picked up a Chatham body that had damage to one end, and am working on it.
I have enough trains(don't tell my Wife I said that)that are runnable, so I like to search the junkboxes for winter projects, plus I get to help bring some back to life.
I won several steamer shells in one auction. Most have been returned to service. These include a gunmetal 225E with a homemade Vanderbilt tender,2037, and a ,Postwar 1666.
I took two damaged short streamlined tenders and made a nice coast to coast style tender. Also a couple of the very rare SP cabooses with the broken roof.
