The late 1930's to early 1950's is my time era.
Railroad names I'm focused on are NYC, PRR, NYNH&H, NP and maybe Great Northern.
I love the historical transitional years of Steam to Diesel there State Side.
Though I am still young into this hobby I have only just started adding to my Hi Rail collection. So far I have a Lionel Hudson, GG-1 & J Class 4-8-4- Pennsylvania which I want to convert to the number 610 which PRR tested on there rail road tracks for a time period during 1941.
