An apparatus for discharging multi-component adhesives of at least two fluidic components onto a granular ballast bed of a railway rail train includes of at least two separate carriages, which can be transferred into a vehicle or a trailer by having the vehicle or the trailer equipped on the inside with rails onto which the carriages can be rolled. The wagons can thus be transported by road to the usage site and can be put into operation by placing them from the trailer onto the tracks of the railway track using extendable rails. The apparatus allows the fully automatic spreading of adhesives over long distances to a ballast bed, so that the ballast bed is bonded in so that trains can continue to run normally. The entire apparatus can be loaded, transported and unloaded on site and put into operation by just two persons.

Provided is a road-rail dual purpose quick disassembly and assembly type rail grinding maintenance robot, including a left robot grinding unit, a right robot grinding unit and quick unit connecting devices. The two robot grinding units are fixedly connected to the left and right sides of the quick unit connecting devices by the quick unit connecting devices so as to achieve quick assembly and disassembly of the robot. Each of the robot grinding units includes a robot grinding device, a rail walking device, road walking devices, a frame, a shell component and an electric control component. The robot grinding device is fixedly installed on the inner side of the upper part of the frame. The rail walking device and the road walking devices are fixedly installed at the bottom of the frame. The degree of intelligent and flexible of rail grinding operation can be significantly improved.

A vehicle for machining a rail by grinding and/or planing, including a metal abrasive module, an eccentric drive performing an eccentric movement, at least two abrasive blocks connected with the eccentric drive, and a force exerting drive pressing at least one abrasive block onto the rail, wherein the metal abrasive module and/or at least one of the abrasive blocks is individually tiltable around an axis parallel to the rail, and wherein at least one of the abrasive blocks is individually pressable onto the rail. This allows a more effective and improved metal removal and rail shaping capabilities.
