The train then proceeded to NorthBay.

As noted, the tractive powerof the locomotive without booster operat-. Fig. 3. Booster Test, with Mikado Locomotive 150, from mile 26 to mile performance with booster cut in, on 1% grades, and conditions of throttle opening, reverselever position, steam pressure, speed, drawbar pull, grade, and curve at all times. _ drawbar pull increased from 37,000 to42,000 lb., speed remaining constant mile at 10 miles an hour, but drop-ping to 9 miles an hour on the 6 degree12 minute curve, while drawbar pull in-creased to 43,000 lb. at this speed. Thetrain was thus handled into Cobalt with-out difficulty, by making the boosteroperative twice for short intervals onthe hardest pulls. It will be noted thatthe line representing steam pressure in-fig. 2 is straight. The reason for thisis that mikado locomotive 150, in com-mon with the others of its class usedby the T. & , and Pacific type lo-comotive 157, proved to be an excep-tionally free steamer, so that no devia-tion of any importance from th
