Abstract: The invention relates to a method and a device (1) for grinding a profile of a rail track intended for rail-bound vehicles using a grinding body. The support is arranged on the device (1) for translatory movement in a plane transverse to the profile by means of a guide (12) and can be applied against the profile by a contact element (13, 14) such that the support carrying the grinding body automatically aligns itself in the transverse plane in respect of the profile and in respect of the device (1). Furthermore, the support for the grinding body can be moved in a translatory oscillating manner parallel to a longitudinal axis of the profile during rotational movement, such that a profile section is worked by the grinding body multiple times and the grinding outcome is substantially improved by the translatory movement.

Abstract: A machine for track maintenance is manually displaceable on a track. The machine has a work module with a handle, a working tool powered by a drive and a machine frame configured to be guided on a rail of the track. The work module is detachably connected to an energy module and the energy module has an electrical energy store and output contacts. The output contacts are detachably connected to input contacts of the work module. The work module has as the drive an electric motor supplied with electrical energy from the energy store. This solution results in a high degree of overall efficiency because the energy available in the energy store serves for the largest part for covering performance peaks.

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 grinding machine for grinding rails of a track has a machine frame, on which guide rollers for manual movement of the rail grinding machine in a longitudinal direction are mounted. By use of a cross slide, which is mounted on the machine frame, a grinding unit can be moved in a transverse direction. The cross slide contains a closed cross slide frame, which extends in the longitudinal direction and the transverse direction. The closed cross slide frame enables a simple and stable construction of the rail grinding machine and flexible adjustability of the grinding unit.

Abstract: Methods and apparatus for orienting and operating grinding motors and their associated mechanical parameters for rail applications are described. A method for determining a parameter for operation of grinding motors on a grinding vehicle, may include: receiving a rail profile, comparing the rail profile with a target rail template to provide a comparison result, and determining, by a processor, based on the comparison result, one or more of a grinding motor's orientation, power, and speed.
