Page 40 of the Dolzall brothers book "Diesels from Eddystone" describes the DR-4-4-750 as a "Horsepower boost for a lagging seller." Baldwin dropped the DR-4-4-660 model and introduced the new 750 HP DR-4-4-750. The Atchison, Topeka & Santa Fe (AT&SF) purchased nine in August 1948 and 21 units were sold in 1949 to six different customers.

gollark: Er. Probably. Again, is the disk set to be mounted on boot?
gollark: I wasn't actually there, so did it do anything which wasn't solved by manually removing it?
gollark: In general, bugs which somehow mess up computer IDs are likely to cause damage *anyway*.
gollark: I don't know how it would have gotten onto computer 0.
