The train was then taken throughto Englehart, 138 miles north of NorthBay, the booster being used on the stiffpulls, with a degree of success equal tothat displayed in its performance in thetest between miles 15 and 18. On May 10, the same locomotive wasstarted from Englehart south with atrain of 32 loaded cars, 4 empties, thedynamometer car, T. & Ry. officialcar Temagami, and caboose. The actualtonnage was 1,800, contents 957, tare843, and the adjusted tonnage, T. & rating, 1,995. Fig. 2 shows the re-. Fig. 2. Booster Test, with Mikado Locomotive 150, from New Liskeard to Cobalt. Showing conditions of throttle opening, reverse lever position, steam pressure, speed, drawbar pull, grade and curve at all times. the Pacific type locomotives equippedwith the booster were given in CanadianRailway and Marine World for June, The tractive power of these Pacificis 36,600 lb. without booster; weight ondrivers 155,000 lbs., cylinders 23 x 28in. They are thoroughly modern in alldetails of design and construction, andare notable as embodying practically all power, is ordinarily 1,200 adjusted tons,so that the excess loading was 301 ad-justed tons. The speed of the train whenit reached the foot of the gradewas 26 miles an hour. The full lines inthe left hand chart show the variationsin speed and drawbar pull until the trainfinally stalled on the grade, 528ft. south of mile 11.
