A system for increasing adhesive coefficient in a contact area of a wheel with a rail comprises a hopper with abrasive material, a nozzle connected to a pipeline, and an accelerator with a jet. In addition, the system comprises a controlled reducer for supply of compressed air connected by a piping to a feed line, as well as pneumatic cylinders of return and gradual action connected by piping to a system control unit, which receives a signal from a manual switch of the angle of attack and controls the angle of accelerator to the rail surface. |
