Abstract: A valve housing for a control valve, particularly for a rail car pneumatic brake system, includes at least one fluid interface for enabling fluid communication with a valve assembly, such as a distributor valve and/or a relay valve assembly, to be mounted thereon for controlling a fluid flow through the housing and an electronics interface for connecting to an electronic module.

Abstract: A digital train brake testing and train preparation assistant uses a system, method, and computer program for determining a component parameter of a train. The system may include sensor nodes mounted to a respective part of the train, wherein the sensor nodes form a sensor network on a rail car, wherein railcars form a wireless mesh network, and wherein each of the sensor nodes is configured to collect data of the component of the respective part of the train and to publish the collected data into the wireless mesh network. The system may further include a server system configured to receive the published data of the wireless mesh network and to determine the component parameter of the train based on the received data. Furthermore, a user device for displaying a component parameter determined by a system, method, and computer program for determining a component parameter of a train is provided.

Abstract: An interface adapter for a control valve of a rail car pneumatic brake system, wherein the control valve has at least two housing compartments being in fluid communication with each other via a fluid interface, includes a fluid interface duplicate for enabling fluid communication between the housing compartments through the interface adapter and a further interface being in fluid communication with the fluid interface duplicate for enabling access to the fluid communication between the housing compartments from outside the housing.

Abstract: A brake assembly for a rail car includes at least one brake element for pressing against a rotor of a rail car wheel in case of a braking action; an actuator for driving the brake element, a linkage for transferring a braking force from the actuator to the brake element, at least one sensor device for measuring at least one parameter of the brake assembly, and the brake assembly further includes a trigger unit configured to enter its active state when a braking action occurs, wherein trigger unit activates the sensor device in the active state.

Abstract: A tread brake assembly for a rail car includes at least one brake block for pressing against a tread of a corresponding rail car wheel, a piston actuator powered by a fluid for driving the tread brake assembly, a brake rigging for transferring a braking stroke from the actuator piston to the at least one brake block, at least one sensor device for measuring at least one parameter of the tread brake assembly, and the tread brake assembly further includes a stroke detector having an active state in which the stroke detector activates the sensor device, wherein the stroke detector is configured to enter its active state upon detecting a force, stress, strain or motion of the brake block, the brake rigging and/or the actuator.

Abstract: A monitoring and diagnostics system for a rail car that includes multiple sensor units, each comprising sensor devices and a data transfer unit, wherein the set of sensor units includes at least one power harvester, which is configured to convert ambient energy into electrical energy, and one energy storage means, which can be configured to store the electrical energy generated by the power harvester, a sensor hub which includes a communication subsystem and a receiver, wherein the data transfer units are configured, so that the sensor units transfer detected/measured data to the sensor hub and the communication subsystem is configured, so that the sensor hub transfers the data to the receiver, either with cable or wirelessly.
