Power required for the APT (IM-APT-225)

Last updated on 24 July 2014 4:11
The coefficient of adhesion available for traction is assumed to be 0.075 at 250km/h. The coefficient of adhesion available for traction at 0 speed is assumed to be 0.225. For the APT, the significance of high adhesion at low speed is only important on severe gradients and then only occasionally.
