I've seen turntables still in use. I saw the one in Steamtown for ex. I try to model just modern stuff. I've seen Altoona shop pics also and they've stayed w/ me. I've modeled my CSX Selkirk engine fueling shed. I thought about a factory by either EMD or GE. I'm now considering trying to capture the shops at Altoona.
Has anyone modeled this??? Looks like a lot of real estate for O gauge???
