Abstrakt:
The article deals with the possibilities of improvement of the vehicle guiding behaviour in curves of small radius (300 m and less) through the modification of the wheelset/track coupling. Due to the unsuitable contact conditions between the wheel and rail there is a place of the slipwave creation at the head of the inner rail and intensive side wear of the outer rail. Special railhead profiles could be one of the possible solutions to sinking the force effect between vehicle and track.
Except design of the railhead profiles, first results from the operation are presented.
