| CTR 7580 was originally constructed by EMD in 1957 for the Pennsylvania Railroad as GP-9 7128, carrying that number through Penn Central and into Conrail. Under the ownership of Big Blue, it was rebuilt as a GP10 and renumbered 7580. After retirement in the 1980s, the Geep was sold into private ownership and worked freight and passenger trains on the ex-CNJ line out of Jim Thorpe, PA. Its last place of operation was the Pennsy Supply quarry at Annville, PA, the reason for all the white markings all over the former Conrail paint scheme. |
