An in-dicator shows the three positions, off, series, and mul-tiple. An ordinary standard air-brake controlling valve isat the right of the controller. The controller wheel haspainted spokes to indicate the various positions ; one blueand one red spoke are diametrically opposite. A foot-catch locks the wheel when not in use and clicks intonotches on the inner surface of the latter. On the top of the controller is a voltmeter, and just inthe rear and a little above is an ammeter. Both these^instruments are of the Weston illuminated-dial type. Theammeter has a capacity of 5000 amperes. It is needlessto say that the indications of this instrument are veryinteresting during the operation of the locomotive,. INTERIOR OF CAB, 362 ELECTRIC RAILWAY GAZETTE. Vol. XIII. No. 20. The air-pump works automatically. After a loss ofpressure, either from whistling or operating the brake,the little motor starts up and pumps the pressure up to 80pounds, when its circuit is broken and it stops, ready forthe next drop of pressure that may occur. The entiremotor is flexibly supported on rubber cushions. It isseries-wound and appears to operate sparklessly atall speeds. The cab is lighted by six lights, which arecontrolled by a switch. The trolley shoe is a massive, shuttle-shaped, brass cast-ing. As is known, the trolley groove consists of two Z-bars placed side by side. During the first trips of thelocomotive the rough Z-bars caused a brilliant sparking,which gave rise to considerable adverse criticism from thepublic, who were ignorant of the conditions. When thecontact surfaces became smoothed there was absolutely notrouble from this cause. The sparking is now as light astha
