GraB : Advantages

The Gravity Brake (GraB) is a system that uses gravity as braking force. The techniques implemented allow to use the weight of the train to apply the brake shoes on the rails.

Thanks to the system, braking distances can be divided by 5.

1. Power

GraB can stop a high-speed train driving at 300 km/h in 600m instead of 3,000m.

2. Braking power

Adjustable braking power.  The GraB can serve both as traditional brake and as emergency brake. 

3. System

The system works even in case of power outage; the braking effort does not require any external input of energy.

4. Maintenance

Reduced maintenance costs. It is not necessary to dismantle the whole braking system to replace braking shoes.
