Patent number: 10336307Abstract: An electronically controlled pneumatic (ECP) overlay control valve can selective switch between a conventional pneumatic mode and an ECP mode. In ECP mode, the overlay control valve shunts the brake cylinder pressure of the pneumatic control valve which allows a relay valve to build or exhaust pressure in the brake cylinder in response to an electronically controlled apply/release circuit. In conventional pneumatic mode, the overlay control valve disconnects the relay valve and allows a conventional pneumatic control valve to control the pressurization and exhausting of the brake cylinder.Type: GrantFiled: September 22, 2016Date of Patent: July 2, 2019Assignee: NEW YORK AIR BRAKE, LLCInventors: Keith Parnapy, Derick Call

Patent number: 10328922Abstract: 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.Type: GrantFiled: January 13, 2017Date of Patent: June 25, 2019Assignee: NEW YORK AIR BRAKE, LLCInventors: Deepak Kumar, Folkert Horst

Patent number: 10286937Abstract: A system that can automatically control the emissions of each locomotive in a consist to reduce overall train emissions. An emissions module determines the amount of emissions emitted by a train. An emissions control module commands the locomotive, via the train control system, to operate in a predetermined state to achieve a particular amount of emissions. A location module can track the location of the locomotive of the train relative geographic locations having emission regulations so that the emissions control module can command appropriate changes in the locomotive to reduce emissions.Type: GrantFiled: January 17, 2017Date of Patent: May 14, 2019Assignee: NEW YORK AIR BRAKE, LLCInventor: Keith Wesley Wait

Patent number: 10173651Abstract: A computer controlled locomotive brake (CCB) configured for setting and releasing the retainer valves of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the retainer valve release pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all retainer valves are released and the train has sufficient braking system recharge to safely control movement of the train.Type: GrantFiled: February 21, 2017Date of Patent: January 8, 2019Assignee: NEW YORK AIR BRAKE, LLCInventor: Eric C.

Patent number: 10144403Abstract: An equalizing reservoir backup system that offers air brake control to the operator when the air brake network has failed or when the computer control equipment of the air brake system has failed. The system includes an equalizing reservoir backup module that is programmed to receive the electrical signals from human machine interface and configuration messages from the computer controlled braking system via the network and to control the train brake pipe via equalizing reservoir control. The equalizing reservoir backup module follows network pressure commands when commanded to do so or transforms handle commands into equalizing pressure when commanded to do so or when communications with the network have been lost. As a result, the backup system can be used when the network has failed or when the computer equipment has failed.Type: GrantFiled: April 5, 2016Date of Patent: December 4, 2018Assignee: New York Air Brake, LLCInventors: Konstantinos Vilaetis, Erich Leonard

Publication number: 20180273061Abstract: A train control system configured to automatically execute and ensure compliance with all requirements for radio blocking. A radio blocking module of the physical train control system of a lead train retrieves and displays the appropriate clearance points for acceptance by the train driver of the lead train. Once accepted, the clearance points are transmitted to a trailing train for display and acceptance by the train driver of the trailing train. An accepted clearance point is passed to the train control system for use as the next destination point for navigation purposes. The train control system can also electronically log all acts to comply with applicable radio blocking requirements.Type: ApplicationFiled: March 23, 2018Publication date: September 27, 2018Applicant: NEW YORK AIR BRAKE, LLCInventor: Folkert Horst

Publication number: 20180251142Abstract: A predictive maintenance system for determining when an item of equipment on a rail car is due for servicing. A server is configured to receive run data relating to a train and a database is associated with the server to maintain identifying information about the rail car, status information about an item of equipment, the date when the item of equipment will likely be due for servicing, and the current location of the rail car. The service date is calculated from the run data by estimating the amount of wear that likely has occurred based on the run data. The estimated amount of wear may then be used to determine the amount of wear remaining and the date when the equipment will likely reach its lifespan based on estimated use to date and the rate of usage.Type: ApplicationFiled: March 3, 2017Publication date: September 6, 2018Applicant: New York Air Brake, LLCInventors: Keith Wesley Wait, Bradley Howard
