Interlocks are arranged for compressed-air-operated switches, trolley, and rheostats. Bow trolleys with rollingcontact were found to be suitable for the low speeds. 346 ELECTRIC TRACTON FOR RAILWAY TRAINS References.

This 12.3-mile tunnel thru the Alps is the longest in theworld. The grade is 0.7 per cent, thru one-half, and 0.2 per cent, thruthe other half of the tunnel. The tunnel is very hot and moist, but it isventilated by means of fans, the air having a velocity of 7 m. p. h.

Mixed service. Water power is used for electric train haulage and comes from twocentral stations having a total capacity of 2700 h. p. The system used is the 16-cycle, three-phase, with 3000 volts on thecontact line, and also on the stator of the motors. Each locomotive has two motors with cranks on the rotors whichconnect thru Scotch yokes to the driver side rods. Two class 2-6-2 locomotives, built in 1907, each have two 550-h. p.slip-ring type motors, the control of which is by pole changing in theprimary and resistance in the rotor or secondary. The speed is 21 or43 miles per hour. Two class 0-4-4-0 locomotives, built in 1909, each have two 850-h. p.squirrel-cage type motors, the control of which is by varying the voltageto the stator. The speed is 16, 21, 33, or 43 m. p. h. Leading and
