Most 3rd rail operations were nominally 600 volts and their equipment was designed to operate at that voltage even though the BMT power plants usually generated only 550 V. According to a friend of mine who was a NY Central engineer, NYC voltage at the feeders was as high as 720 V allowing for a voltage drop along long distances yet the R-32s operated on the NYC just fine. AFIK, the IRT did generate the full 600 V. |
