摘要： A locking mechanism for a brake cylinder that has a tube surrounding the hollow shaft of the brake cylinder with a first set of teeth formed along an outer surface thereof. A gate having a second set of teeth corresponding to the first set of teeth is moveable in between a first position, wherein the first and second set of teeth are engaged to prevent movement of the brake cylinder piston, and a second position where the first and second set of teeth are disengaged to allow movement of the brake cylinder piston. A spring biases the gate into the locked position and a supplemental piston responsive to a source of brake pipe pressure can move the gate into the unlocked position so that the main piston is free to move.

摘要： A brake controller having independently adjustable friction and detent torque to allow for easy adjustment of handle feel without changing or replacing components. The brake handle is coupled to a cam that rotates with the handle and has a series of divots in its outer circumference corresponding to established brake handle positions. A detent roller is biased by an adjustable spring into engagement with the outer circumference of the cam and thus into the divots when the handle is moved. A separately adjustable spring biases a lateral surface of the cam into engagement with a frictional surface. Independent adjustment of the two spring can adjust both detent and friction torque, thus allowing a user to easily adjust handle feel without having to change or replace handle components

摘要： A system for optimizing the control of a train that includes an interface for receiving data representing a set of operational parameters for a train that will traverse a predetermined route. A server is interconnected to the interface and programmed to generate a plurality of scenarios using the same set of operational parameters but different control parameters. A simulator is programmed to perform a simulation of the operation of the train as described by the operation parameters and control parameters. The server is programmed to review the results of the simulation and score how closely the simulations achieved one or more performance metrics, thereby identifying which control parameters should be used by the train and allowing the control parameters to be transmitted to the train.

摘要： An air dryer having a heater element associated with its valves to prevent freezing at cold temperatures. The air dryer includes a temperature sensor and an electronic controller that reads the temperature sensor during normal operations and selectively opens and closes certain of the valves when the temperature falls below a predetermined threshold to enter a safe mode that avoids freezing of the valves during operation. If an exhaust valve is open when safe mode is entered, the corresponding inlet valve is closed, both of the exhaust valves are closed, and the other inlet valve if opened. If an exhaust valve is not open, both inlet valves are opened and both exhaust valves are closed.

摘要： 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.

摘要： 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.

摘要： An electrical trainline junction box formed from a housing having first and second opposing sides, an identification module positioned in the housing, and first and second receptacles positioned in each of the first and second opposing sides. The first and second receptacles have a plurality of electrical contacts arranged in a predetermined geometry so that only one possible orientation and electrical connection to trainline flanges is possible. The flanges include contact pins in inserts coupled to the flanges by sleeves. The outer surface of the inserts and the inner surface of the sleeves are keyed to allow only a single orientation of the inserts relative to the sleeves. The outer surface of the sleeves is shaped to allow only a single orientation of the sleeves relative to the flanges, thus ensuring that the proper electrical connection is made when the junction box is installed.

摘要： An improved air supply control system for a locomotive that includes a global positioning system (GPS) and a track database having the locations of rail road tunnels. Locomotives equipped with one or more air compressors and/or an air dryer are operated by the air supply control system to, firstly, minimize unnecessary air compressor operation in a tunnel and, secondly, to operate only the compressor and air dryer of the lead locomotive in a consist if the air supply system must be operated while the locomotives are in a tunnel.

摘要： A powered hand brake for locomotive brakes that latches a brake chain into a locked position after the brake cylinder has applied the locomotive brakes. A computer controlled brake system may be interconnected to the brake cylinder and the latch and programmed to set the latch into the latched position when the brake cylinder has moved the locomotive brake into the applied position. An actuator is coupled to the brake chain to take up slack in the brake chain as the brake chain moves between the first and second positions. The actuator can comprise a motor or a tensioning cylinder that takes up slack in the brake chain after the brakes have been applied. Alternatively, the actuator may comprise a linkage connecting the brake chain to the locomotive brake so that the slack in the brake chain is taken up as the brakes are applied.

摘要： A locomotive brake controller that has a body configured to interconnect to a desktop location in the cab of a locomotive and a mount that can attach the base of the controller to a vertical stand in the cab of a locomotive. The controller also includes an operator interface adaptor that can be clocked relative to the body and an operator face plate that can be clocked relative to the mount depending on the location of installation to ensure proper tilting of the interface relative to the operator and proper orientation of the operator display. Alternatively, the adaptor may include a fixed face plate that includes a moveable display and an adhesive membrane with operator buttons to properly orient the display.
