EMC, GM-EMD, EMD DIESEL-ELECTRIC LOCOMOTIVES

The following is a list of locomotives produced by the Electro-Motive Corporation (EMC), and its successors General Motors Electro-Motive Division (GM-EMD) and Electro-Motive Diesel (EMD). For locomotives built by GMD go here.

Ed's note: This page is a work in progress and there are many, many EMD locomotives. We're adding the links and pages as quickly as possible. Thank you!

 

Switchers (SW/NW/SC/NC/MP)

The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine models after the more powerful 567 model engines replaced the Winton engines. The "C" designation stood for cast frame locomotives and the "W" designation for welded frame locomotives. EMC standardized on welded frames after 1939. The "T" and "TR" designation stood for transfer locomotives.

The SC and SW switchers were the first locomotives produced in EMC's new factory after its completion in 1936. The pre-SC and Model 90 switchers were development design locomotives outshopped in 1935.
