Abstract: The invention relates to a machine for use in track sledding operations. Machine (1) comprises a wagon (2) having adjustably carried therebeneath a multibladed plough (3). A rail clamp assembly (4) is included for suspending the track above the plough during the sledding operations.

Abstract: A vehicle dynamics prediction system for providing prediction of vehicle velocity for a predetermined future time period. The predictions utilize future vehicle control setting anticipated for the time period. An artificial intelligence database coupled to a processor that utilizes weighted values for neural network models representing dynamic performance of the vehicle forms part of the vehicle dynamics prediction system.

Abstract: The invention provides roller rail clamp apparatus for use in lifting a rail for operations such as replacement of ballast or resurfacing of a railway. The apparatus comprises parallel pairs of spaced-apart lift roller assemblies mounted to a support for positioning a pair of clamping to a rail of the track, each the lift roller assembly comprising at least one pair of rollers, wherein each the roller of a roller pair rotates on an axis in an essentially vertical plane adjacent a rail and the rollers are on opposite sides of a rail when a lift roller assembly is clamped thereto with the head of the rail releasably retained upwardly of flanges at the lower ends of the rollers; means for adjustably connecting the apparatus to a carrier thereof; a lift mechanism for adjusting the vertical position of the support relative to the carrier of the apparatus; and a tilt mechanism for applying torque about a horizontal axis to linkage between members of a pair of lift roller assemblies.

Abstract: An open stator axial flux asynchronous induction electric motor has an open stator having two spaced insulating supports with a slot extending from a periphery of each of the supports to an inner location. A plurality of poles extend between and are secured to the supports. The stator has either distributed winding or salient phase pole windings associated with at least some of the poles with an opening between adjacent poles in the regions of the slots in the supports. The motor has a rotor with a shaft extending through the slots and at right angles to the supports. Two spaced rotor discs are present on the shaft and are located at either side of the stator. Each disc is made of a magnetically permeable material and has either an inner face of electrically conductive material or an inner face with conductive paths which function as rotor windings.
