Mostly Postwar, in particular operating cars and accessories. There are a couple of pieces of prewar, #203 & # 1666E engines and a set of 600 series passenger cars. As to the rest, I've put together a set of 2500 series passenger cars and added examples of the modern era cars to complete them (sleeper, combine, etc.) as well as Williams Madisons, Lionel and K-Line 027 streamliners, and all the types of Postwar engines I wanted as a kid: originals, MPC reissues, and Williams repros, along with a Lionmaster PRR T-1.
I am retired now, the collection is complete and my dream layout is finished, up and running.
I got the most toys! I win!
