A large number of Union Pacific diesel locomotive cabs, with some Norfolk Southern cabs mixed in, sit in the Larry's Truck and Electric facility in Lordstown, Ohio. I saw almost 800 different diesel locomotives (and I know I missed many more), from some almost completely scrapped, to many being just the cab left like in this photo, to newly rebuilt engines. It is quite an impressive facility. Photograph taken with permission from LTEX, wearing all required safety gear.
