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 brake control system and method for a train having a lead locomotive or control car, at least one trailing locomotive or control car and, optionally, at least one railroad car. The lead locomotive or control car generates data representing an independent brake demand and data representing an automatic brake demand and transmits the data representing an independent brake demand and the data representing an automatic brake demand to the at least one trailing locomotive or control car. The at least one trailing locomotive or control car receives data representing an independent brake demand and data representing an automatic brake demand and controls a brake cylinder pressure of the at least one trailing locomotive or control car based on the data representing an independent brake demand and the data representing an automatic brake demand.

A method and mechanism for initiating an emergency stop for an unattended railcar is disclosed. The method may include using a trip arm placed alongside the railway tracks at a designated stop point that may contact a portable trip-cock lever arm that extends out beyond the perimeter of the railcar if the railcar reaches the stop point as it moves along the track. The trip-cock lever arm may be attached to a valve that is connected to the pneumatic brake system of the unattended railcar. As the trip-cock lever arm rotates, the valve may open to release the air pressure in the pneumatic brake system causing the brakes to engage the wheels causing the railcar to stop.

Provided are a brake system, a brake device, and a method of controlling brakes for railroad cars in which control can be multiplexed with a simple configuration. In a brake system 1 for railroad cars includes brake control devices 11, 12, 13 provided in railroad cars 101, 102 103 respectively that form a unit 104. Each brake control device 10 (11, 12, 13) is capable of outputting information of the corresponding car (101, 102, 103) to the other brake control devices 10 through a transmission device 20. The brake control device 10 can calculate a total necessary braking force value BRA required for braking all of the cars 101, 102 103 using the information output from the other brake control devices 10 to the transmission device 20.
