GE BB40-9W

The GE BB40-9W is an 8-axle narrow-gauge road switcher version of the popular GE C40-9W locomotive. All 141 examples of this locomotive are owned by the EFVM railroad in Brazil. They are equipped with four B-style trucks, two at each end replacing the conventional C-style trucks. This is necessary because EFVM tracks are 1,000 mm (3 ft 3 3⁄8 in) narrow gauge. Unlike the North American axle load limit of 71500 lb (32.4 tonnes) on standard gauge railways, the narrow gauge railway over which the units operate allows only 51190 lb (25 tonnes). The units are numbered 1113 to 1253.
