  • Patent number: 12188185
    Abstract: A jacking tie and method of using a jacking tie to level and/or lift a railroad track. The jacking tie is configured with an elongate body that is configured to span beneath two parallel rails of a railroad track. Preferably the jacking tie is of the configuration to replace a standard railroad tie. The jacking tie has two jacks, preferably hydraulic cylinder jacks that are positioned so as to lift each of the parallel rails of the railroads. The jacking tie body has two sections. A track support shell is supported by the hydraulic cylinder jacks. The track support shell is configured for nesting or mating engagement with the lower body shell in a compressed or resting position. The hydraulic jack cylinders are configured to lift the track support shell away from the lower body shell, thus lifting the rail positioned above the hydraulic jack cylinder. The track support shell and lower body shell are pivotally connected such that the ends of the track support shell can be independently raised.

  • Patent number: 9890503
    Abstract: A monoblock concrete crosstie for railway tracks that achieves a high performance in operation includes a steel structure that is formed from ultra-resistant high strength steel plates embedded in a concrete element and having pre-stressed cold rolled wires with ends that form button head knots which are anchored to the steel plates. A faceted geometry allows optimal material usage and in turn increases the crosstie-ballast interlocking and stability with respect to the support surface.
