Balancing speed
The vehicle speed for which the installed track cant in a given curve offsets the centrifugal acceleration (balance the centrifugal force, i.e. nca = 0 m/s 2 ) is called balancing speed.
Bogie yaw resistance
Torque around the vertical axis between bogie and vehicle body, required to rotate a bogie while supporting a vehicle body.
Cant of track (superelevation)
The increase in height of one rail compared to the other to change the track crosslevel.
Cant deficiency (CD)
The missing cant, necessary to balance the centrifugal force for a given R and V ...
