Rick:
So if I understood what you said correctly, and I measure correctly, the Bachmann skeleton cars are about 12" long which is, in 1:20.3, about 20 feet. So the 16 foot long lengths would be, though on the short end, prototypical. The 80 to 120 foot humongous ones were using disconnects (must be!) and with my small layout I’m not going to go to that length anyway (that’s 4 to 6 feet long IRL!).
So when people talk about lengthening the Bachmann skeletons (or creating their own) they are more targeting a 40 foot (prototype) car for the 36 foot lengths eh?
I have such short sidings that I think I’ll stick with the 12" cars for now and see how I like it…
Thanks for the historical context guys! Great stuff to know…
