20130096740 | System and Method for Determining Whether a Locomotive in a Consist is in Leading Mode or Trailing Mode - 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 | 04-18-2013 |
20130066490 | SYSTEM AND METHOD FOR INTERFACING WITH A PORTABLE REMOTE SPEED CONTROL SYSTEM ON A LOCOMOTIVE TO ENHANCE SPEED CONTROL AND A SPEED MEASUREMENT DEVICE THEREFOR - A portable mounting assembly is provided comprising a mounting disc comprising at least one magnetic component for attaching the mounting disc to an axle bearing on a vehicle such as a locomotive, for determining speed; and a stabilizer bar attached at a first end to the mounting disc and at a second end to an outrigger comprising at least one magnetic component for attaching to a stationary component of the vehicle. A method of providing speed control to a portable remote control system for a locomotive is also provided. A method of overriding a speed control mode operated by a portable remote control system for a locomotive is also provided. | 03-14-2013 |
20120160125 | Method and Apparatus for Controlling and Enhancing Tractive Effort in DC Traction Motors on Locomotives - A system is provided for powering a locomotive. The system comprises a plurality of traction motor assemblies, each assembly comprising an armature and a field; a first power source connected in series to each armature; and in specific circumstances, a second power source connected across the fields. A method of controlling traction power in a locomotive is also provided, the method comprising: identifying which of a plurality of traction motor armatures in the locomotive has a highest current reading; and ramping a traction motor field current to equal the highest current reading for the traction motor armatures. | 06-28-2012 |
