  • Patent number: 4658730
    Abstract: Apparatus for continuously surveying and aligning railroad track has a measuring system with a leading point and a trailing point, both points being on the track center line. Two tensioned wires extend between these points, respectively, and a common intermediate point also on the track center line. At the trailing point a shadow board is located and this is arranged to interrupt an infrared beam extending between a projector at the leading point and a receiver behind the trailing point. A device measures continuously the angle between the two wires and this value is averaged and then subjected to mathematical manipulation in a computing device to derive an ordinate value for the shadow board which is automatically extended accordingly. The receiver then commands a track correction ram located adjacent the shadow board to move the track radially inwardly or outwardly until alignment between projector, receiver and shadow board causes the receiver to stop the lining action.

  • Patent number: 4367681
    Abstract: An improved technique for correcting errors in track, for example errors in alignment and cross-level. A record of the actual geometric condition of a section of track is obtained by running a recording car operating at a predetermined speed and axle loading over the track. A record which may be on magnetic tape is thus obtained for one or more parameters such as alignment. In some cases this record may be used directly to derive electrical error signals which control a track moving device which moves the track in a direction to remove the error. Where the parameter of interest is alignment and the section of track is curved, a desired geometric condition has to be obtained for comparison with the actual geometric condition to derive the electrical error signals. One way of obtaining the desired geometric condition is to process the record to achieve a running average taken over ten or so consecutive sample points.

  • Patent number: 4203367
    Abstract: A device for lifting and/or lining railroad track, which device extends longitudinally of the track and is mounted at one end on a truck carrying track engaging wheels, and the other end is adapted to be connected to a propelling vehicle. Reaction blocks are provided on the beam in the region of the other end, and a track position correcting frame is carried between the reaction blocks and the end mounted on the truck and close to the other beam end. The device provides a lifting and/or aligning attachment for, say a tamping machine, which attachment substantially absorbs all its own lifting and/or lining forces and transmits them to the track rather than to the tamping machine. The device also provides a track position reference means to provide information on the displacement of the lifted and/or aligned track.

  • Patent number: 4176456
    Abstract: A track aligning device for monitoring the curvature of a track and adjusting the track successively to correct the curvature incorporates two taut wires mounted on a car or cars running on the track, the wires each defining two chords each extending between a pair of spaced points located on the track center line. Preferably the cords overlap. Each chord operates as a reference line which cooperates with a respective measuring device. A first measuring device located nearer the rearward point of the first chord derives a voltage which is sampled at equal intervals, say 2 meters, as the aligning device passes along the track. The voltages are summed and averaged electrically and a voltage equivalent to the mean displacement of the track from the first chord is obtained. The second measuring device is located nearer the rearward point of the second chord and derives a voltage equivalent to the actual displacement at that position of the track with respect to the second chord.

  • Patent number: 4083775
    Abstract: A screening device suitable for cleaning railroad ballast which has become fouled with use, and of the type in which ballast to be cleaned is fed into a screen member to separate the coarse or ballast stone from the fines, the stone being reused to ballast the track. A screen member of generally frusto-conical shape, open at each end, is rotatably mounted on a track running frame, with the axis of the screen extending substantially parallel to the track and either horizontal or slightly inclined to the horizontal. The screen member is rotated so that centrifugal action results in the fouled ballast, loaded into the narrower open end of the screen member, moving up the walls thereof to its larger open end. The fines pass through the screen member and the stone is collected at a stone receiving member located adjacent the wide end of the screen member.

  • Patent number: 4048353
    Abstract: Holes in railway ties are drilled and impregnated with creosote or other preservative using a hollow drill with consecutive drilling and creosote injection cycles, either at the time of rail mounting or in a prior processing stage so as to produce a tie with improved resistance to deterioration, for example due to ingress of water in the tie hole. The invention enables the preservation of pretreated ties, which are subsequently drilled to receive spikes for rail tie plates, by continuing the skin of creosote or other preservative from the outer surface of the tie to the walls of the drilled hole. A sealing collar assembly is mounted on the drill to prevent egress of preservative from the hole during the injection process.

  • Patent number: 3952665
    Abstract: A method and a system for correcting the misalignment of a railroad track is provided which corrects the track by the steps of applying a force laterally of the track to move it in the direction of its correct position, sensing the track position relative to a datum, automatically reducing the force in response to the sensing step, permitting the track to react to the reduction of the force and automatically rapidly repeating the force application, sensing, and reduction steps to set up a vibratory cycle of force application until the desired track condition has been achieved. The system provides a valve which has a rail position feeler in the hydraulic connection between pump and jack, which feeler upon sensing the rail operates to close the valve to terminate a jacking action. Pressure sensitive switch is provided in the hydraulic connections between the valve and the pump that operates to exhaust the jack when a pre-determined pressure has been built up in the connections between the pump and the valve.
