My only 3 rail set as a youngster was a Marx set given to me by a family whose older boy had "outgrown" his toy train set. (I got my other 3 rail "fix" from a friend that had a Lionel set.)
My Marx was a NYC lithographed set and to this day I recall the NYC Pacemaker boxcar the black NYC gondola and the NYC Pacemaker caboose, and its tinplate steam engine. (However I can't remember if there was a tank car or not.) I had a ton of fun with that set! The fork couplers worked GREAT. You barely touched them together and they were hooked and ready. Uncoupling was a bit of a pain, as I recall.
Anyway, I played with that set for several years until I "graduated" to a Lindberg HO train set with an SW switch engine. Loved that set, too!
Marx are cool. Really like those lithograph F units.
