Union Railroad (URR) Roundhouse in Monroeville, PA

(Satellite)

If you are here because of the Pennsy Pitcairn Railyard, then you need to go there.

Union RR roundhouse in Hall, Pa (Pittsburgh area). Scan off a Kodacolor negative, summer 1978 IIRC. I don't know if it still exists.

Brandon Peck: Still there and in service

"The URR is a Class III carrier that offers round-the-clock switching services to southwestern Pennsylvania's Monongahela Valley. Customers can reach NS, CSXT, WLE, and BLE." [transtarrail]

Warren Caudle: What railroad used this?

John Sobaszko: [Union Railroad] was once probably the largest "terminal" railroad with over 100 locomotives, back in the early 1970s. It was owned by US Steel, before being spun-off to Transtar. It now has 32 SW1500s/MP15s that it operates in sets of up to five units.
