    摘要: A brake pipe control apparatus of the type that defines primary and control passage networks has been improved. The primary passage network interconnects the brake pipe to at least one pneumatic valve in the apparatus. The control passage network interconnects a source of control pressure to at least one magnet valve used to cause operation of the pneumatic valve(s). The improvement includes first and second check valves and a passageway added between the two passage networks. The first check valve is incorporated into the control passage network between an inlet channel thereof that connects to the source and a branched channel thereof that connects to the magnet valve(s). The first check valve is situated to prevent air from flowing to the source from the branched channel when pressure in the source is low relative to pressure in the branched channel. The passageway interconnects the branched channel and the primary passage network. Placed into the passageway, the second check valve is situated to allow air to flow from the primary passage network to the branched channel when pressure in the source is low relative to pressure in the brake pipe. Pressure is thus maintained in the branched channel thereby allowing the magnet valve(s) during operation thereof to cause proper operation of the pneumatic valve(s) of the apparatus even if the source fails to provide air at the control pressure ordinarily expected.

    摘要: A handle assembly, of the type used in railway locomotives, which includes a base plate, a cam mount attached to the base plate, a cam disk and a shaft assembly interconnecting the mount and disk to allow rotation of the disk. The improvement includes a yoke, a bail bar, first and second bearing members anchored to the plate and first and second switches attached to the plate. Pivotally connected to the disk and accommodating a handle, the yoke rotates along with the disk as the handle is moved along its range of motion and tilts as the handle is moved perpendicularly thereto. The bail bar is rotatable between the first and second bearing members. A first mechanism imparts a rotational force to the bail bar so that its middle section presses against an upper portion of the yoke. A stop limits rotation of the bail bar to a point at which the yoke and handle attain an untilted state. Operating against a lower portion of the yoke, a second mechanism provides a counterbalancing force to normally bias the yoke in the untilted state. No matter where the handle is positioned along its range of motion, when it is tilted by a preset amount, the yoke overcomes the rotational and counterbalancing forces so that a third mechanism causes both the first and second switches to change state.

    摘要: An improved method is used to control the pressure in the brake pipe of a train. The train is equipped with an automatic brake handle, an equalizing reservoir, a brake pipe control device and a computer for controlling the control device according to position of the handle. The method involves the steps of: moving the handle to a point along its range of motion; and storing in the computer as a setpoint the value desired for the pressure in the brake pipe. At whichever point the handle occupies along its range of motion, there is a particular pressure setpoint corresponding thereto. The method next includes the steps of: directing the computer to command the control device to modify the actual pressure in the equalizing reservoir to the setpoint thereby also causing the actual brake pipe pressure to approach the setpoint. As the actual brake pipe pressure approaches the setpoint, the computer is directed to command the control device to adjust the actual equalizing reservoir pressure to a value slightly above (if desiring to increase brake pipe pressure) or below (if desiring to decrease brake pipe pressure) the setpoint until the actual brake pipe pressure reaches the setpoint. While monitoring the actual brake pipe pressure, the computer then commands the control device to adjust the actual equalizing reservoir pressure to maintain the actual brake pipe pressure at the setpoint corresponding to position of the brake handle.

    摘要: Method and apparatus for controlling braking on a train having ECP railcars using a conventional automatic brake valve. The locomotive and railcars are connected to brake pipe and a wireline, or use RF communications. A brake handle or other brake control valve interface is operated to cause a pressure change in an equalizing reservoir. The relay valve is isolated from the pressure change and connected to a reference pressure whereby brake pipe pressure is maintained. The pressure change is sensed and a signal generated representative thereof which is used to determine the level of braking commanded on the railcars. The apparatus includes an interface unit interposed between pertinent ports connecting the automatic brake valve, equalizing reservoir and brake pipe, and an equalizing reservoir pressure sensor to provide an output signal to an ECP controller for controlling braking on the railcars.

    摘要: The function of a two-way end-of-train (EOT) system is coordinated with the operation of the brake equipment on a locomotive of a train according to the steps of a novel method. This method enables the brakes to be applied during an emergency in a way which minimizes the buff and draft forces produced within the train. The method includes the steps of: (1) monitoring the train for signs of an emergency by using the brake equipment of the locomotive; (2) determining, if an emergency has occurred, whether the emergency is due to disjoining of the train; (3) waiting a preset time period, if the emergency was caused by disjoining of the train, before causing the brake equipment of the locomotive, to command the two-way EOT system to initiate an emergency application of the brakes from a rear part of the train; and (4) waiting an alternative time period, if the emergency was caused other than by disjoining of the train, before causing the brake equipment of the locomotive to command the two-way EOT system to initiate the emergency application of the brakes from the rear part of the train.
