Wasila Tycoon Make sure you have realistic acceleration enabled, it makes train dynamics and stats a lot more interesting. Depending on the weight of the train, the power of the engine and the gradient of the slope it's going up or down, the acceleration is changed. Notes is also available in http://zenmurali.blogspot.inELECTRIC TRACTION PART - 02TRACTIVE EFFORT REQUIRED FOR PROPULSION OF A TRAINDIFFERENCE BETWEEN MASS A. In general, HP = TE * speed/308 (TE in pounds force, Speed in mph) The limit on the low end is usually the thermal capacity of the traction motors. But just by 3. The manual provides in-depth information on how to play. A while ago, a maximum tractive effort was added to the train model -- besides the power of the engine. Tractive effort becomes at least as important as horsepower when choosing a train; heavier trains and hillier routes will need more TE. 4. If you don't feel up to writing full articles then this may be a better place to start. * Running Costs/year Designed Lifespan Capacity TSRY: Original TTD name ($) km/h (mph) Most yard switching applications seldom exceed about 30,000 pounds of tractive effort and speeds of 5 to 7 miles per hour. In other words, it is the sum of the tractive force and rolling effort on the road surface.
