Conrail inherited its rare SW1001 fleet from the Reading. These 1000hp switchers were commonly found on the ex-Reading branches in eastern Pennsylvania and throughout the eastern end of the system.
Because of their common use in cab signaled territory, a number were outfitted with cab signal and or LSL equipment.
