HISTORY OF THE EMD GP7 & GP9
General Motor’s Electro-Motive division first introduced the GP (General
Purpose) locomotive in 1949. As it’s name indicates, the “Geep” was the
locomotive the railroads were looking for - a versatile locomotive that could
do anything. They were used by numerous railroads to pull every conceiv-
able kind of train - way freight, branchline passenger, transfer drag, com- 19 36,37 18 17 16 34 15 35 14 13 12
