The tractive effort is 34,000 lbs.,giving a ratio of 1 to with the weight on drivers and 1to with the total weight. The normal horse power whichcan be developed is 2,200 or 550 per motor. This, how-ever, can be increased to 3,000 at starting or for shortintervals in running. The motors are of the gearless type,the armatures being mounted directly upon the axles of thedriving wheels. The specifications call for a maximum speedof these locomotives of from CO to 65 miles per hour, whichwith the 44 in. driving wheels, will give about 460 ofthe motors. This speed is to be made with a 500 ton trains of greater weight two of the locomotives can becoupled together and operated on the multiple unit system. The first experimental locomotive of this type, which wasNo. 6,000, was
