The normal speed, with load on the level,was to be 60 m. p. h., yet the locomotive was to be safe at 80 m. p. h.,for use on a New York-Philadelphia run. Tests called for accelerationof trains on a 2 per cent, grade with one motor cut out. Controllerswere required to carry as high as 7000 amperes at GOO volts. Weight of the locomotive is 314,000 pounds of which 200,000 pounds,or 64 per cent., are carried by 4 sets of 72-inch drivers, and 114,000pounds by 4 sets of 36-inch bogie wheels, 324 ELECTRIC TRACTION FOR RAILWAY TRAINS D D uj:k\ d I W).G)~.
