Notes
(1) Two Class 47s were repowered with Ruston-Paxman engines, 47601 with a 16RK3CT, and 47901 with a 12RK3ACT. These engines produce 3250 and 3300 horsepower respectively.
(2) The Class 47s powered by Sulzers were derated to run at 2580 Horsepower by the mid-1960s, so it's safe to assume that this will also apply here.
(3) brush i fucking hate you. Some Class 47s apparently had Series-Parallel Transitions, and others straight Parallel Transitions. Why? I haven't the faintest fucking clue. The All Parallel Units would have 4260 Amps for the Max Generator Current. The Max Traction Motor Currents would remain the same. As for the steps and shunts: 1 for Steps, 1 for Shunts.
