The master switch is in the middle of the cab, and isso situated that the operator has a clear view in all directionswithout leaving his seat. The weight of the locomotive and equipment is 25 tons, all ofwhich is on four 41-in. drive wheels. Two 150-hp, 25-cycle,. HIGli-TENSlUN £Ll-XTI<iC (jTlVE FUR SWEDEN single-phase motors are geared, one to each axle, with a gearreduction of 18 to 70, and have shown an ability to handle a70-ton train at 40 , without exceeding the rise of tem-perature for which they were designed. The equipment hasbeen so installed on the locomotive as to permit ready accessto all parts. Only the small operating devices have been placedin the cab, and the layout is such as to allow the greatest con-venience in operation with maximum safety to the operator. ■ JET VS.
