Rick, you're spot on with the A1G Roadnames: Norfolk Southern (the first one), Cotton Belt/SSW, Monon and Reading.? Photos of each are on the A1G site (shameless plug).
The Walthers releases on the left of the original photo were also made by Roco and should be the same as the A1G cars, excepting perhaps a bit of tooling cleanup and in my opinion a little better paint job.
That the Bachmann releases could also be from Roco is something I haven't considered up until now.? Somewhere I think I still have one of the CB&Q cars and can do a comparison... if I can locate it.
Cheers,
George
