Dunno if this helps, but here's a few comparison shots (terrible, blurry cellphone photos) of a 45 Tonner or two with a Bachmann 2-8-0. And one or two with a railtruck and an LGB caboose. The gray boxcar is the AMS navy one.

You can see an LGB stock car behind the 45 tonner in the one wtih the goose.
