Mike - Post WWII is when the diesel began to take over on the railroads . . . I've got a 1938 edition which is probably 80% or better steam, and most of that is about as developed as USA steam got. It includes the N&W "A" class and the Challenger and bunches of 4-8-4's, as well as the Union Pacific three cylinder 4-10-2 and 4-12-2 types. My next one is the 1966 Car and Locomotive edition . . . about 80% cars and nothing steam it appears. Seems I've heard that the first or second post-war edition includes steam and gas/coal turbines as well as conventional steam and diesel, but I've not seen a copy. http://www.abebooks.com dealers usually list a number of these in different editions, BTW.
