A variable valve (10) that can proportion the amount of pressure provided by the control valve (CV) of a rail car to the brake cylinder (BC) of the rail car based on the loaded state of the rail car. The variable valve (10) has an arm (14) that extends to contact the side frame of a rail car in response to a brake application to detect the loaded state of the car. The arm (14) provides a variable amount of biasing force against a proportional spool (60) that is moveable to close communication between the pressure output (22) from the control valve (CV) and the pressure inlet (26) of the brake cylinder (BC). As a result, the proportional spool (60) will close communication between the control valve (CV) and the brake cylinder (BC) at a lower pressure for an unloaded rail car than a more fully loaded car.

Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all retainer valves are released and the train has sufficient braking system recharge to safely control movement of the train.

The coupling may be disconnected by simple rotation of one coupling half relative to the other and by pulling the coupling apart as done by current rail car decoupling procedures without the need for manual manipulation of extraneous locking mechanisms.

SYSTEM FOR PROVIDING TEMPORARY SPEED RESTRICTIONS TO LOCOMOTIVES
A system for automatically updating route information to a locomotive that includes a route computer and voice radio encoder that merges data representing temporary changes in a route with a voice radio call placed by a dispatcher to a locomotive engineer. A voice radio decoder coupled to the locomotive cab voice radio extracts the data representing the temporary changes from the voice radio signal and provides the data directed to the energy management system so that there is no need for the engineer to manually enter the temporary data.

A train speed profiling system for use in connection with a train management system that can generate a virtual profile of a predetermined route having an estimated time of arrival at a destination based on data specific to the route and the actual train that will travel on the route. The virtual profile may be adjusted for any acceleration and any deceleration required by the train, and then optimized for reduced fuel consumption by reducing braking effort and improving coasting opportunities over the route if the estimated time of arrival is earlier than a desired time of arrival. The virtual profile may further be conformed so that the estimate time of arrival matches the desired time of arrival within a narrow threshold.

The system includes an equalizing reservoir backup module that is programmed to receive the electrical signals from human machine interface and configuration messages from the computer controlled braking system via the network and to control the train brake pipe via equalizing reservoir control. The equalizing reservoir backup module follows network pressure commands when commanded to do so or transforms handle commands into equalizing pressure when commanded to do so or when communications with the network have been lost. As a result, the backup system can be used when the network has failed or when the computer equipment has failed.

A locomotive air brake control system that responds to penalty braking requests from external systems by applying a varying amount of train brake level based on monitored and calculated parameters in order to enforce a defined train condition. The system may include a minimum acceptable train braking, a condition to be achieved to prevent further application of train brakes, and a maximum train brake level to be applied in response to the request. Alternatively, the system may apply braking in stepped levels according defined thresholds for a train behavior variable of interest such as speed or deceleration. The system may be configured to incrementally apply and release train brakes during the adaptive penalty, and may also adjust the level of braking according to calculated braking capacity of the train.

The controller is also programmed to determine when an automatic bail off should be inhibited and/or cancelled depending on ongoing train conditions.

A gladhand coupling that prevents inadvertent separation of the coupling halves without the need for additional structure or manipulation to connect and disconnect the halves. Each half is equipped with a lug having two spaced apart ramped pads and a flange defining a channel having a corresponding ramped pad. When two halves are positioned together then rotated into the locked position, the ramped pad of the flange is positioned proximately to the either of the ramped pads of the flange to prevent inadvertent lateral compression of the two halves that would otherwise cause unintentional uncoupling. The coupling may be disconnected by simple rotation of one coupling half relative to the other so that the ramped pad of the lug is positioned between the spaced apart ramped pads of the lug and by pulling the coupling apart as done by current rail car decoupling procedures.

Train brake safety monitoring and fault action system with PTC brake performance assurance
An intelligent, on-board, train brake safety monitoring and fault action system is disclosed. The system compares measured dynamic train brake performance using on-board train control system, such as a LEADER® system. Using the measured dynamic train brake performance, the brake monitoring system can determine whether the train is capable of stopping within a particular required distance, such as a stop distance set by a positive train control system in which the train is participating. The ongoing ability to meet external braking criteria, such as compliance with positive train control stop distances, may be used to extend the interval between any mandated train brake inspections and tests.
