System and method for monitoring condition of rail car wheels, brakes and bearings

Patent Number: 8439315
Publication Date: 2013-05-14
Inventors: ;

A system and method for detecting failing rail car wheels, brakes, bearings, and/or other components of a rail car may include at least one thermal sensor and at least one image capture device. The thermal sensor(s) and image capture devices(s) are usable to help determine whether there is a failure or potential failure of a component of a wheel set by detecting, measuring and/or comparing a temperature of various portions of the wheel set. If the temperature is higher than expected, it may ...

Roller assembly for a railway switch

Patent Number: 8430364
Publication Date: 2013-04-30
Inventors: ; ; ; ;

A roller assembly for facilitating movement of a switch rail between two positions. In one embodiment, the roller assembly includes a frame adapted for attachment to the switch rail and having a pocket formed therein, and an elastomer assembly, at least a portion of which is slidably disposed within the pocket. The elastomer assembly includes a roller wheel and an elastomeric block. The roller wheel travels along the surface of a tie plate when the switch rail is moved between positions. ...

Train wheel bearing temperature detection

Patent Number: 8430363
Publication Date: 2013-04-30
Inventors: ; ; ; ; ;

A system (10) for sensing a condition of a rail vehicle undercarriage component (e.g., 18) includes a sensor (e.g., 12) comprising an array of infrared sensing elements (29). Each of the elements may be aimed at a different region of a target area (e.g., 32) of a rail vehicle undercarriage component to generate respective scanning waveform signature data corresponding to each different region. The sensor may be oriented so that at least one of the elements ...
