A cutting tool assembly for milling a rail top, includes a first section and a second section mounted to the first section. Each section includes a plurality of insert-receiving pockets for receiving a plurality of different types of cutting inserts. The plurality of different types of cutting inserts are arranged in a plurality of helical teeth that may be separated by a helical chip flute. In one embodiment, a first type of cutting insert is formed with a radius, R, a second type of cutting insert is formed with a radius, R1, and a third type of cutting insert is formed with a radius, R2, to perform a milling operation on three different areas of the rail top.

The present invention relates in particular to a mold (M) for aluminothermic welding of a metal rail (1), which comprises at least two substantially identical pieces or shells (4), configured to be temporarily assembled opposite one another and on either side of said rail (1) to enclose the head (10), web (11) and foot (12) of this rail (1), each piece or shell (4) having an upper opening (43), which opens onto an internal cavity (44) bounded by walls (45, 46, 48) configured to enclose the head (10), the web (11) and the foot (12) of said rail (1), characterized by the fact that said internal cavity (44) comprises a compressible sealing coating (5) only against the walls (451, 46, 48) configured to enclose said web (11), foot (12) and underside of the head (10), with the exception of the rest of the head (10) and the underside of the foot (12).

The system described herein relates to machining the running surface of a rail by means of at least one rotating, chip-removing shaping tool which can be moved along the rail and can be pressed at least against its running surface. In order to create advantageous design conditions, it is proposed that after the machining with the chip-removing shaping tool at least one rolling body which is adapted to the shape-machined rail surface is rolled over the rail, with cold deformation of the running surface of the rail, in order to level out unevenness of the running surface of the rail.

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 energy storage acting as a buffer store is feedable into the direct current network via an associated one of the power converters.

A portable rail weld milling machine apparatus comprises a metal frame that incorporates a motor with a rotary carbide tool that is able to lock to a rail or rails for stability. The apparatus houses the required guides and motors to maneuver the tool on a plurality of axes with computer numerical control (CNC). The CNC programming is able to control the carbide tool such that the welded rail can be milled to proper profile on the entire running surface, including the top, the field side, and the gauge side of the ball of the rail.
