Various embodiments of a braking system for at least one bogie or railway vehicle comprising an emergency braking control unit made according to a first safety integrity level and a service braking control unit made according to a second safety integrity level lower than said first safety integrity level are described; the braking system carrying out at least one additional braking function at the same safety integrity level as the emergency braking control unit.

Methods, systems and a kit for indicating brake air pressure status in brake pipes of multiple interconnected train cars are provided. The methods include operating at least one end-hose adapter per train car. Each end-hose adapter is mounted between a train car end hose and a brake pipe to be in fluid communication therewith and are configured to sense the brake air pressure in the brake pipe. Each end-hose adapter kit includes connections adapters for connecting either end to different parts of the train car system. The end-hose adapter provides a first visual indication when the brake air pressure is within an operable range and/or a second visual indication when the brake air pressure is below an operable value and is experiencing leakage.

In a method of braking a number of rail cars of a train travelling on a mainline track, in response to a unique braking command provided to each rail car of a first subset of rail cars, wherein each braking command includes a level or percentage of braking the brakes of the rail car are to assume, the brakes of the rail car are set to level or percentage of braking included in the unique braking command provided to the rail car. Thereafter, in response to a unique braking command provided to each rail car of a second, different subset of rail cars, the brakes of the rail car are set to level or percentage of braking included in the unique braking command provided to the rail car.

The current invention relates to a method for monitoring a wear of a brake element (6) of a rail wagon (1) by means of a monitoring system (9, 4), said rail wagon (1) comprising a brake assembly (2) comprising said brake element (6), said brake assembly (2) further comprising a brake regulator device (7) comprising a first part (71) at a first end and a second part (72) at a second end for automatic adjusting of a clearance (13) with respect to said brake element (6), said clearance (13) relating to a braking of a wheel (3) of said rail wagon (1), said method comprising a plurality of steps.

A method for generating compressed air of at least one vehicle is described, comprising the step of:)

a) selectively connecting a first compressor, or a second compressor, or simultaneously the first compressor and the second compressor, to an electric motor arranged to generate a driving torque.

A system for generating compressed air for at least one vehicle is also described.

A device for detecting obstacles for a rail vehicle includes a pilot bar, which is retained on the bogie frame of the rail vehicle in front of the wheelset that is positioned first in the direction of travel via a mounting retainer, wherein the mounting retainer is formed by vertically arranged spring elements, in particular leaf springs, where each leaf spring is fastened at an upper end to the bogie frame and at a lower end to the pilot bar, where each leaf spring includes a stress-strain converter which is arranged between the upper end and the lower end on a broad surface of a leaf spring, and where each stress-strain converter is connected to an on-board evaluator via a signal-conducting connection.

A system for retarding the speed of a railcar comprises a brake; a hydraulic actuator moving the brake between a closed position in which the brake applies braking pressure on the wheel of a railcar, and an open position in which the brake does not apply braking pressure on the wheel of the railcar; a hydraulic circuit provided with a pump arrangement for supplying hydraulic fluid to the hydraulic actuator; and a control circuit coupled to the hydraulic circuit for controlling the flow of hydraulic fluid to move the brake between the closed and open positions.
