Online Calculation of the Pulling Force and Power / achievable Speed

By default the required power and the necessary pulling force of a Railjet (locomotive “Taurus” 1116 and seven passenger cars) at a speed of 230 km/h are calculated.

• Suitable values for cars, bicycles and other trains you can find by “Make a choice”.
• With the default values you are able to perform a calculation immediately by simply pressing the button “Calculate” or the enter key!
• You can do the calculation several times, too. Just change the values in the white fields!

This calculator uses SI units!!

* For these values set a minus in front of the number!

Instructions for this Calculator

• One oft the following items can be calculated if all the other values are known:
  • Maximum speed. Normally the maximum speed is limited by the engine’s running speed.
  • Power and traction force
  • Maximum tractive effort on starting as a result of the coefficient of static friction.
  • Gradient
  • Possible acceleration
  • Mass of the railroad cars
  • Coefficient of static friction required
• The listed coefficients of friction apply only at relatively low speeds.
• As comma you have to use a point.
• When calculating, engine and drive efficiency can be considered. As standard, an efficiency of 100% is assumed!
• The calculation is only valid if the load on each axle is approximately the same.
• No guarantee can be given for the correct function – for corrections and suggestions for improvement, please use the contact form!

Comparative Values for Maximum Traction, Hourly Power, Mass and µ_H

Please note: the maximum traction is given in kN, the hourly power in kW and the mass in t! K is the abbreviation for kilo and means 1000, so 1 kW = 1000 W, 1 kN = 1000 N.
