Cargill No. 6751

Cargill No. 6751, built in 1940 with works number 1111, was one of the first SW1s that the General Motors Electromotive Division built. After buying the unit, the B&O gave it a running number: 213, then it was renumbered to 8413, then to Arco Petroleum as their number 8417, then to 6971, until it came to Cargill as their number 6751. In mid-August 1993, it moved to the USRM when it was replaced by a Trackmobile.
