Patent number: 8738202Abstract: To avoid a locomotive from travelling with a disabled sanding system, a method and system are provided for ensuring that the sanding system is not disabled if a primary speed reference used to detect the locomotive's speed is faulty. The method comprises determining a first speed measurement from a primary speed source; if the first speed measurement is below a setpoint, determining a second speed measurement from a secondary speed source; and if the second speed measurement is below the setpoint, disabling the automated and/or emergency initiated sanding control system on the locomotive.Type: GrantFiled: November 18, 2011Date of Patent: May 27, 2014Assignee: ZTR Control SystemsInventors: Aldo Liberatore, Amarjit Soora, Lucas Pul

Patent number: 8538610Abstract: By taking a pressure reading at a particular port on a multiple-unit braking valve, e.g. the MU-2-A valve, and comparing such a reading to a main reservoir pressure, one can identify whether the locomotive in which the valve is situated is in trailing mode or leading mode. In particular, it was found that the pressure on port 63 of the MU-2-A valve is indicative of which mode the locomotive is in since port 63 is exhausted to atmosphere in lead mode whereas it is at or near the pressure in the main reservoir which is readily distinguishable from atmosphere.Type: GrantFiled: December 4, 2012Date of Patent: September 17, 2013Assignee: ZTR Control SystemsInventor: Aldo Liberatore

Patent number: 7680566Abstract: A consist controller is provided that enables an operator to take advantage of all horsepower combinations for locomotives in a consist. The consist controller provides a fractional increase option and a fractional decrease option that enables the operator to increase or decrease horsepower output with finer adjustments. In a preferred implementation, the fractional increases and decreases are used in conjunction with a fuel optimization routine such that the target setpoint, from which a range of horsepower values is computed, can be increased or decreased in steps that are less than a full notch increase or decrease.Type: GrantFiled: August 31, 2007Date of Patent: March 16, 2010Assignee: ZTR Control SystemsInventor: Aldo Liberatore

Patent number: 7339283Abstract: An electronic load regulation system for a locomotive may comprise a solid state replacement for existing electro-mechanical load regulators that are used to adjust the excitation current in the field windings of the locomotive's generator. A pressure sensor may include a first chamber and a second chamber, each chamber having a pressure switch. The pressure sensor may be installed in place of a prior art vane motor and may connect to the existing governor hydraulic output. The pressure switches send status data to an electronic load regulator circuit that may replace a prior art rheostat. The electronic load regulator may increase or decrease the excitation current depending upon the status data received from the pressure sensor.Type: GrantFiled: April 27, 2006Date of Patent: March 4, 2008Assignee: ZTR Control SystemsInventor: Viktor Gvelesiani
