EMD F7B, D&RGW 5603, 5-Stripe Scheme. In fact, more F7s were built than all other F units combined. It succeeded the F3 model in GM-EMDs F unit sequence, and was replaced in turn by the F9. Final assembly was at GM-EMDs La Grange, Illinois plant or GMDs London, Ontario facility.
The F7 differed from the F3 primarily in internal equipment (mostly electrical) and some external features. 40,000 lb (18,000 kg) for an F7 with 65 mph (105 km/h) gearing, compared to 32,500 lb (14,700 kg) for an F3 with the same gearing. A total of 2,366 cab-equipped lead A units and 1,483 cabless-booster or B units were built. Note: the B unit is often referred to as an F7B, whereas the A unit is simply an F7. For clarity, BLI refers to A units as F7A.
Many F7s remained in service for decades, as railroads found them economical to operate and maintain. However, the locomotive was not very popular with yard crews who operated them in switching service because they were difficult to mount and dismount, and it was also nearly impossible for the engineer to see hand signals from a ground crew without leaning way outside the window. As most of these engines were bought and operated before two-way radio became standard on most American railroads, this was a major point of contention.NEW Paragon3 Sound & Operation System FEATURING ROLLING THUNDER.
