A locomotive brake system includes a plurality of electronic air brake controllers for controlling at least a train brake pipe and a locomotive brake pipe interconnected by a communication network. A communication port and a system controller are connected to the network. The system controller controls the configuration of the electronic air brake controllers for standard mode and remote mode of the brake system and assembling EAB network signals for communication between a remote locomotive controller to be connected to the communication port and the electronic air brake controllers.

Remote control brake system and manifold

An electronic brake controller for an electropneumatic brake system includes a housing; at least one brake operator mounted to said housing and whose position defines desired brake action; a display on said housing; a signal output on the housing; and a multiple position switch on the housing. A controller in said housing determines the position of the operator and the multiple position switch, provides one of operator position signal and desired brake action to the output and drives the display to display desired braking action as a function of the determined position of the operator for acceptable operator positions, and drives the display with a brake system variable and adjusts the variable as a function of the position of the multiple position switch for don't care operator positions.

Electronic brake controller with selectable display

A control system which allows electro-pneumatic control of an equalizing reservoir with the capacity to create penalty applications in a purely pneumatic manner. A controller for the equalizing reservoir includes an electro-pneumatic source of pressure or atmosphere responsive to an electrical equalizing pressure control signal and a pilot valve selectively connecting the electro-pneumatic source or atmosphere to the equalizing reservoir in response to pressure in a pilot port of the first pilot valve. A magnetic valve is provided having a first input connected to a second source of pressure, a second input connected to atmosphere and an output connected to the pilot port of the first pilot valve. At least one penalty valve is connected to the pilot input of the first pilot valve and is responsive to a penalty signal to connect the pilot input to atmosphere. A fourth valve has a first input connected to the second input of the first pilot valve and an output connected to a third source of pressure lower than pressure in the equalizing reservoir prior to a penalty signal. The fourth valve connects its first input to its output in response to a penalty signal. A method of initializing the electro-pneumatic source of pressure or atmosphere responsive to an electrical equalizing pressure control signal.

Electronic equalizing reservoir controller with pneumatic penalty override and reduction limiting

A brake controller for a locomotive includes a train brake pipe, a locomotive brake pipe, a brake cylinder, a control valve and a relay valve. The first control input of the relay valve is selectively connected to one of the output of the control valve and the locomotive brake pipe; and the second control input of the relay valve is selectively connected to the locomotive brake pipe when the control valve output is a release signal. A first electro-pneumatic valve, when activated, causes the control valve to be a release signal. An electronic controller is connected to a first pressure transducer for the locomotive brake pipe, a lead/trail mode switch and the first electro-pneumatic valve; and activates the electro-pneumatic valve for brake release pressures in the locomotive brake pipe when the mode switch is in the trail mode.
