Track Braking
Railhugger bogie with brakes in off position. Hydraulic pressure is applied to the suspension cylinder to lift the brake shoe clear of the rail.
Railhugger bogie with brakes applied. When hydraulic pressure is exhausted due to operation of the governor overspeed device or by manual operation of the hand valve, the vehicle weight is transferred to the brake shoes, which on contact with the rail effects full train braking.

Additionally we recommend our Pinch Braking system for use on steep gradients or where further braking is required to stop unbraked rolling stock.
Where gradients are particularly steep, or where large unbraked loads are currently in operation, we have developed a high capacity system offering the added security of Calliper Braking.
Both Pinch and Calliper braking are applied directly onto the track/rail, this negates the risk of inducing uncontrolled skidding, unlike conventional wheel applied brakes.
Pinch braking
The pinch brake during normal running is held clear of the rail by hydraulic pressure within the suspension cylinder.
When hydraulic pressure is exhausted, the vehicle weight is transferred via the rail top brake shoe, which activates the pinch brake through a system of crank levers.
Calliper braking
During normal operation, hydraulic pressure retains the calliper brake clear of the rail.
When the braking system is applied either manually or by the governor overspeed device, the vehicle weight is transferred to the rail top brake shoe, which hydraulically triggers the spring applied side brakes.
