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.
