Note:

1.

Sold to Northrup-Hendy Co., Hawthorne, California, in late 1946; used as test bed for non-aircraft applications of Turbodyne 10,000 HP turboprop aircraft engine; scrapped.

The two-unit power set was loaned (leased? sold?) in December 1946 to Northrup-Hendy Company, a joint venture of Northrop Aircraft Company and Joshua Hendy Company formed to advance the development of turboprop aircraft engines. The experiment to use the turboprop engine for non-aircraft purposes was abandoned and the two-unit set of locomotives sat on a spur at Northrop Aircraft's plant at El Segundo, California, until they were scrapped in December 1947.
