An integrated pneumatic and electropneumatic train brake system and method of operation. An electropneumatic brake controller in at least one of the locomotives provides an emergency brake signal on a brake pipe and the network to the pneumatic and electropneumatic brakes for an emergency position of the operator interface. The brake controller also provides an emergency signal only on the network to the electropneumatic brakes in the continuous service position of the operator interface.

An electropneumatic brake control valve unit capable of operating at the interface of the emergency brake portion or the service brake portion of a standard brake control valve as a retrofit unit or operating as a stand alone electropneumatic unit. The unit includes electric valves responsive to electrical signals and sensed brake pipe pressures to operate pneumatic valves to control the brake cylinder. The pneumatic valves are also operable independent of the electric control valves so as to allow braking with the electrical controls off or disabled. The unit can operate in combination with a complete brake control valve or with either or none of its emergency and service portions.

A method of transitioning between the pneumatic and electric modes of an integrated pneumatic/electro-pneumatic train brake system which includes a brake control having a common operator brake controller. Initially, the control applies the brakes in response to the operator brake controller in the present mode. The control enables the next mode upon request from the operator and applies the brakes in the next mode to match the applied brakes in the present mode. Once the present mode brake is released, the control and system switch to the next mode. Other brake controllers monitor the network and automatically switches modes based on the status of the network.

303 222, 303 226, 303 7

A method of controlling the empty/load setting on cars having electropneumatic brakes. A first signal is set to an empty/load status. The first signal and a second signal is transmitted to the cars. The cars set their empty/load status to the status and in response to the receipt of both signals. The cars transmit their empty/load status, and the empty/load status of the cars is received and displayed.

303 7, 303 86

An interface system including locomotive and car electrical trainline terminals, locomotive and car brake pipe ports and a locomotive pressure supply port. A train brake pipe valve controls pressure on the train brake pipe port. A controller monitors pressure on the locomotive brake pipe port and controls the train brake pipe valve in response to pressure on the locomotive brake pipe port. The controller also provides ECP commands on the train electrical terminal in response to pressure on the locomotive brake pipe port and provides electrical power on the train terminal from the locomotive electrical trainline terminal. The car electrical terminal is connected to the ECP trainline for providing ECP commands and power to the ECP equipped train devices. The controller may also control an emergency valve to produce an emergency on the locomotive brake pipe port. A transition valve on the brake pipe port allows bi-directional connection of the interface system.

303 3, 303 15, 303 66, 303 81

A relay valve configuration which can be used with various cars in an electropneumatic train and under the control of one of the electropneumatic brake control valves. The improved brake control valve includes a relay valve mounted at an interface of the manifold. The valve has a source inlet connected to the reservoir interface port, an inlet connected to atmosphere, an outlet connected to the brake cylinder interface port and a control inlet connected to the exhaust interface port. The valve is responsive to the control inlet connected to the exhaust interface port to selectively connect the brake cylinder interface port either to the reservoir interface port or atmosphere. The exhaust interface port may be the retainer port. A check valve/choke is also mounted on the manifold of the interface and is in the same housing as the relay valve.
