Ref Atlas possibly doing an 89' flat car, the only thing that worries me slightly is that to do all the potential variants of these, the hitches should be in various different positions to handle different trailer lengths through the years, the Accurail car dealt with this reasonably well (instructions could have been better) but with Atlas's current trend of everything being RTR, how would they deal with that? And yeah, i'm modelling some 70's intermodal stuff at present, and finding Accurail cars at all packaged without a pair of 45' (1980's+) trailers is nearly impossible! I'd already resorted to using Santa Fe cars with the lettering rubbed down as Undecs for a modern TTEX pair! Another for the list, a drop-frame 40' trailer. These were pretty common, but for 70's era trailers we are stuck with the (nice) A-line frehauf kits and the RPP UPS 40' trailer! (Oh, and maybe an occasional Lonestar Models flatbed.
I'd like to see Proto 2000 make a nice set of Baldwin RF-16's "Baldwin Sharks" both A and B units, in B&O, or undecorated being I can paint them B&O myself so... Not to picky on the paint scheme... An 0-6-6-0, to follow the first Mallet in America, "Old Maude" for the B&O... Made by Rivarossi, or Proto 2000... And last but not least, a B&O EM-1 by Rivarossi or even Proto 2000! All are offered in Brass, but dang, not from this modelers wallet!
