Disclosed is a brake system for a railroad vehicle, including a parking brake provided with a piston and having a first configuration in which the piston is in a working position in which it acts on a lining support and applies a predetermined force to a brake disc; a second configuration in which the piston is in a rest position in which it does not act on the support and does not apply any force to the disc; and a third configuration in which, when the vehicle is not at a standstill and the ambient temperature in the environment of the disc is greater than a threshold value, it forces the piston to move towards a trip position different from its working and rest positions, in order to limit or cancel the force applied to the disc.

A railcar safety lock incorporates a rectangular channel having an open top face and a pair of opposing open ends. An “L”-shaped bracket is pivotally secured within the channel. A pad lock aperture is secured within the channel adjacent a second open end opposite a first open end. The safety is configured to lockingly engage the bracket over a single lever railcar hand brake, thereby preventing the hand brake lever from being released.

A control system for wheel-slip prevention in a railway vehicle with a pneumatic brake is provided. The control system comprises an input interface configured to accept a deceleration reference for controlling the pneumatic brake, and a memory configured to store a reference governor providing executable instructions for modifying the deceleration reference upon its violation of a wheel-slip constraint, and configured to store a controller providing executable instructions for mapping the modified deceleration reference to a sequence of control commands for controlling pressure applied by the pneumatic brake. The control system further comprises a processor configured to execute the reference governor to modify the deceleration reference and configured to execute the controller to map the modified deceleration reference to the sequence of control commands. Further, an output interface of the control system is configured to output the sequence of control commands to control the pneumatic brake.

A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

A vehicle control system includes at least one sensor and a power supply control system. The sensor is on board a vehicle system and configured to generate vehicle data relating to a condition or parameter associated with the vehicle system. The power supply control system is configured to control one or more power supplies on board the vehicle system and to receive the vehicle data from the at least one sensor. The power supply control system is also configured to compare the vehicle data to one or more criteria relating to vehicle movement, and, in response to a determination that the vehicle data meets the criteria and receipt of a signal indicative of the vehicle system carrying (or being configured to carry) cargo of a predetermined material, generate a control signal to deactivate at least one of the power supplies.

The system provides for the control of a railway train for the transport of goods, comprising a plurality of wagons a master locomotive at the head of the train and one or more slave locomotives distributed along the train. The train is equipped with a pneumatic brake pipe which extends along the whole train. The master locomotive is equipped with a master control system for controlling the train, and the at least one slave locomotive is equipped with a slave control system subordinated to the master control system. The master and slave systems can communicate with each other via a radio channel. Each slave system is designed to control traction apparatuses, apparatuses for controlling the pressure in the brake pipe and apparatuses for applying the emergency brake of the corresponding slave locomotive, and for retransmitting signals indicating the status of these apparatuses of the slave locomotive to the master system.
