Patent number: 7664459Abstract: A distributed power train (10) communications system for sending and receiving signals between a lead locomotive (14) and remote locomotives (12A/12B/12C) in the train (10). A lead (14) initiated message is received by at least the remote locomotive (12A/12B) nearest to the lead unit (14). The receiving remote unit (12A/12B) retransmits the message for receiving by the next remote unit (12C) in the train. Thus the message leapfrogs down the train from the lead unit (14) to the remote units (12A/12B/12C). When the last remote unit (the nth remote unit) (12C) receives the message, the last remote (12C) transmits a status or other response message to the lead unit's message. The status message is received at the (n-1)th remote unit (12A/12B), which appends its status message and transmits the combined status messages toward the lead unit (14).Type: GrantFiled: March 23, 2005Date of Patent: February 16, 2010Assignee: General Electric Co.Inventors: Eugene A. Smith, Jr., David Michael Peltz, Robert C. Palanti

Patent number: 6824226Abstract: In a distributed power railroad train, an apparatus for equalizing the equalizing reservoir pressure in the remote power unit and the brake pipe pressure in response to airflow into the brake pipe from the remote locomotive. With these pressures equal, the remote unit cannot charge the brake pipe while the lead unit vents the brake pipe to command a brake application at the train railcars.Type: GrantFiled: February 10, 2003Date of Patent: November 30, 2004Assignee: General Electric CompanyInventors: Eugene A.

Patent number: 6443538Abstract: A method to facilitate reducing delays in braking applications in a train using a system. The system includes at least one computer for executing brake control functions of the train and a brake pipe that extends along a length of the train for supplying air for brake operations. The train includes a lead locomotive, at least one remote locomotive, and at least one railcar. The method includes sensing a change in airflow in the brake pipe, determining whether the change in air flow is desired, sensing brake pipe pressure, and filtering undesired fluctuations in brake pipe pressure during brake applications based on the determination of whether a change in airflow is desired.Type: GrantFiled: December 27, 2001Date of Patent: September 3, 2002Assignee: GE Harris Railway Electronics, LLCInventors: Eugene A. Smith, Jr., Milt Deno, Don K. Johnson

Patent number: 6375275Abstract: A brake pipe overcharge detection scheme determines when an overcharge situation occurs followed by an interruption of the brake pipe slow pressure reduction process of the brake system assimilation. When the slow pressure reduction process is interrupted, the rail cars may be left in an overcharged state (i.e., the car braking system is charged to a pressure greater than the normal brake pipe pressure). When the brake pipe pressure is set to its normal brake-release value, the pressure of the car braking systems will be greater than the brake pipe pressure. The car braking system will interpret this positive pressure differential as a request to set the car brakes, and will therefore partially apply the car brakes. As a result, additional drag forces will be encountered by the locomotive as it moves the train, which may result in train separations, and overheating of the car brake shoes and wheels may result in cracked wheels and derailments.Type: GrantFiled: December 30, 1999Date of Patent: April 23, 2002Assignee: GE-Harris Railway Electronics, L.L.C.Inventors: Eugene A. Smith, Jr., Milton C. Deno, Don K. Johnson, Dale H. Delaruelle, Carl Hines

Patent number: 6095618Abstract: A train control system is for a train comprising at least first and second train segments including a brake pipe being separated between adjacent train segments. The train control system preferably comprises a first control subsystem for installation in a locomotive of the first train segment and a second control subsystem for installation in a locomotive of the second train segment. The first and second control subsystems communicate with one another for controlling train braking. The system also preferably includes a third control subsystem for installation in a railcar adjacent an end of the first train segment. This third control subsystem preferably includes at least one pressure transducer for sensing brake pipe pressure adjacent the end of the first train segment, and at least one control valve for controlling brake pipe pressure adjacent the end of the first train segment.Type: GrantFiled: March 19, 1999Date of Patent: August 1, 2000Assignee: GE-Harris Railway Electronics, L.L.C.Inventors: Steven P.

Patent number: 4946229Abstract: An adaptive brake control system monitors a plurality of brake pipe/air line parameters, such as fluid path volume and air flow rate, and controllably modifies action taken by the engineman or performs emergency control of the brakes, in order to continuously enable the brake system to adapt itself to dynamic operating conditions and anomalies in the integrity of the fluid path. In accordance with a pressure reduction modification mechanism, the application of a pressure reduction to the equalizing reservoir is precisely controlled by taking into account the actual state of the brake pipe, so as to ensure that the requested brake application is effected as intended. The control mechanism also monitors the integrity of the fluid flow path of the brake pipe/train air line, so that the engineman may be alerted and a prescribed train safety measure may be effected in the event of a potentially hazardous anomaly in the link.Type: GrantFiled: June 2, 1989Date of Patent: August 7, 1990Assignee: Harris CorporationInventors: Milton C.
