Hopefully this is an easy answer for someone. I was trying to decide whether to keep or sell these and in researching them - couldn't figure out if they are from a single set or not. Couldn't find them listed in a set in my Doyle book. Includes 220 Alco, 6082 gondola, 6825 flat car w girder, 6476 hopper and 6017 caboose. Curious if they were originally from a set and if so details on the set, year, etc...? The Alco AA looks to be from 60-62 era according to Doyle book.
Thanks,
