minute and compressing it to six atmos-pheres. Each compressor consists of two pumps and twomotors, although one set is sufficient for normal operation. Tests of a very severe character gave very good results.The temperature rise of the motor copper at a train speedof 46 m.p.h. and with the locomotive pulling 21,000 lb. forone hour was 69.5 deg. C. With a train of 383 tons and up agrade of 1.1 per cent, the locomotive accelerated to 43.5m.p.h. in 267 seconds. The locomotive shows a consumptionof about 35 watt-hours per ton mile. The other locomotivesadded to the equipment have been previously described andare of the 2-C-2 Brown-Boveri and Oerlikon types.
