In order to improve adhesion force between wheel and rail under water lubrication, a special composite type of conditioning block was developed for rubbing wheel treads during braking under the pressure of adhesion force with the block was investigated by the experiments using a large scale rolling contact testing machine. Then, some braking tests were carried out with railway cars at the speeds of beyond 120 km/h. by applying the block to wheel treads during braking, gross slips were reduced and preferable adhesion characteristics were obtained under wet condition. The adhesion coefficients with the blocks were about 1.4 times higher than the values without the blocks under water lubrication.
