Normally the driver has to maintain tractive effort well below the rail adhesion limit to give himself time to respond to wheel slip.

The system reduces wheel slip but not the manoeuvrability.

It tells the engine's computer to slow the speed of the motors to prevent wheel slip.

Controlled wheel slip can also have a limited cleaning action on the rail head along the length of a train.

When the sensors detected wheel slip, the system would automatically apply gentle pressure to the rear brakes until grip was restored.

In most cases, individual wheel braking is enough to control wheel slip.

The system, controlled by the car's computer, uses wheel-speed sensors to detect wheel slip, and it has two ways to bring it under control.

All of his Pacifics were particularly prone to wheel slip.

Some other automatic lockers operate as an open differential until wheel slip is encountered and then they lockup.

Although some wheel slip was observed, driving was discovered to be possible even at slope angles up to 30 degrees.
