s will be arranged for eightpoles. With the 14-mile combination all motors will be inparallel connected for eight poles, and with the 28-milecombination the four-pole arrangement will be used, re-sistance being used on intermediate steps. A multiple-unit system of control is to be provided forthe independent operation of each locomotive, or for theoperation of two units simultaneously from the control endof either locomotive in whatever order or arrangement thelocomotive may be coupled together. The control equip-ment is arranged and constructed to provide for the useof single-phase current from the pantograph trolley, whichis connected to the primary winding of the main trans-former through a suitable line switch, and from the second-ary of the transformer circuits will be established throughand in connection with the phase converter in such a man-ner as to deliver polyphase current to the main motors. Each locomotive is to be provided with an air compres- Width over cab sheet 10 ft.

This clutch is controlled by the mainreservoir pressure so that the compressor is operated onlyas required. Straight-air and automatic air brakes will beinstalled together with the necessary ventilating apparatusfor the motors. The electrical equipment has been de-signed with special consideration for regeneration and elec-tric braking at grades, both for the purpose of safety andfor economy of operation, the local conditions being veryfavorable for this type of operation.
