Abstract: A system and method is disclosed for predicting and comparing wear scenarios in a rail system. The method can include generating and running a contact model of the interaction between a rail and a train car to produce a simulated loading on the rail for a predetermined time period; generating and running a wear model based on the material properties and/or friction modifier properties of the rail using the simulated loading to produce a simulated wear profile of the rail for the predetermined time period; obtaining a grinding profile to be performed on the rail during the predetermined time period; and generating an updated rail profile by modifying the rail profile by the simulated wear profile and the grinding profile. The method can predict and compare crack growth over time, and provide a financial model and comparison of costs and benefits for different maintenance protocols for the rail system.

Abstract: A rail-mounted rail processing machine has at least one traction motor and with at least one working unit for processing tracks, a permanent energy source, an electrical energy storage and a current collector. The components are connected to a common direct current network via power converters. In order to create a rail-mounted rail processing machine that allows low-maintenance and environmentally friendly operation of working aggregates with strongly varying peak loads without having to accept losses in the processing quality, the permanent energy source is a fuel cell which feeds at least one base load of the working unit into the direct current network via one of the power converters. To cover peak loads of at least the working unit, buffer energy of the electrical energy storage acting as a buffer store is feedable into the direct current network via an associated one of the power converters.

Abstract: A rail grinding machine for grinding rails of a track includes a machine frame with rollers for support on both rails of the track and a swivel drive for swingably mounting a carrier frame to the machine frame for rotation about a pivot axis which extends longitudinally in direction of the track. A grinder is adjustably secured to the carrier frame in an area of one rail, with a drive motor for supplying energy to the swivel drive and the grinder being secured to the machine frame at an area distant to the carrier frame. The distance of the carrier frame and its pivot axis from a support roller located opposite to the grinder is reducible by a length compensation unit which includes a pressure-exerting element for applying in opposition to the distance reduction a force by which the grinder is pressed against a rail head inner flank of the rail being ground.

Abstract: A rail maintenance vehicle includes a slide frame along which a grinder may move while the vehicle remains stationary. The grinder may be moved automatically away from the rail as the grinder moves longitudinally along the rail away from the center of a weld bead in order to smooth the grinding at the weld bead. The slide frame is connected by a linkage mechanism such that the grinder may be oriented at different grinding angles over a range of 200.degree.. The grinder is mounted upon a lateral displacer such that the grinder may be moved from one side of the vehicle to the other for grinding on rails on either the right or left side of the vehicle. A turntable system allows the turntable cylinder to pivot up and out of the way to a horizontal position so that the lateral displacer may move the grinder from one side of the vehicle to the other without interference from a vertical turntable cylinder.
