20090193950 | Automatic Rail Saw - An automatic rail saw includes a frame adapted to be lowered onto a railroad rail by a crane. A lower end of the frame includes a channel for receiving the rail. A releasable clamp mechanism on the frame is operable to clamp the rail in the channel. A saw blade is mounted on the frame for rotation about a rotational axis and for linear movement along a cutting path extending through the channel for cutting of the rail with said blade. The blade is driven by a blade motor and moved along the cutting path by a drive motor. A control system adjusts the rate at which the saw blade moves along the cutting path based on measured parameters such as blade speed, current draw of the drive motor and hydraulic pressure at the drive motor. | 08-06-2009 |

20120199038 | SYSTEM FOR GUIDING RAILS ON A RAIL TRAIN - A system for guiding rails onto a rail train having rail cars with a plurality of vertically spaced rail support shelves includes upwardly opening guide channels extending from funnel members position at the end of the rail car to each shelf in alignment with the outermost rail receiving pockets of each shelf. A guide shoe with a horizontal roller recessed therein and projecting below the bottom of the shoe is mounted on the end of a rail threaded across the shelves and guide channels of the rail support car. An alternative guide shoe further includes vertically extending rollers projecting from the sides of the guide shoe. | 08-09-2012 |
20130096739 | AUTOMATED TRACK SURVEYING AND BALLAST REPLACEMENT - A method of surveying a section of a railway to determine amounts of ballast to be replaced keyed to position coordinates of track locations includes moving a survey vehicle along the railway, optically scanning the track at selected intervals to obtain optical data points with associated position coordinates, recording images at the intervals with position coordinates, recording position coordinates of no-spread zones, processing the optical data points to derive ballast unit weights associated with locations along the track, detecting anomalous unit weights, accessing images associated with the locations of the anomalous unit weights, accessing the anomalous unit weights to adjust as necessary, and loading the adjusted data into a computer of a ballast train to control the application of replacement ballast along the track according to the detected position of the ballast train. | 04-18-2013 |
20130230212 | AUTOMATED TRACK SURVEYING AND DITCHING - A method of surveying a section of a railway to determine amounts of soil to be excavated or added at selected position coordinates of track locations includes moving a survey vehicle along the railway, optically scanning the track structure at selected intervals to obtain optical data points with position coordinates, recording images at the intervals with position coordinates, recording position coordinates of drainage points, processing the optical data points to derive ditch overlays formed by ditch profiles associated with locations along the track and ditch templates, detecting anomalous soil unit weights associated with track locations, reviewing images associated with the locations of the anomalous units, adjusting the ditch overlays as necessary, and loading the adjusted data into a computer of an excavator device for display to guide an excavator operator in reshaping the ditches along the track according to the detected position of the excavator device. | 09-05-2013 |
