The car contained thirty-three reservoirs,capable of carrying 4400 lbs. (2000 kg) of compressed air at 1420lbs. per square inch (100 kg per centimeter) pressure. This wasreduced in the motor cylinders to 280 lbs. (20 kg), as a workingpressure in the high-pressure cylinders, and 140 lbs. (10 kg) in thelow pressure. The reheater was carried under the middle of themotor car. The dimensions of the motor cylinder were ins. x 22-in. stroke (320 mm and 530 mm x 560 mmstroke). The length of the cars over all was 44 ft. ( m). were designed to run at 25 miles (40 km) per hour, and weighedcomplete 50 tons. The geared motors had four poles, and thegearless motors six poles. The arrangement proved too complicated as well as inefficient,and was abandoned in favor of the multiple unit system. Lastsummer the traffic on the line was being cared for by means o
