This paper describes a fundamental study of the preventive measures against electrical pitting on rolling bearings by using electrically conductive lubricating grease. In order to evaluate the ability to prevent the electrical pitting on rolling bear

On the sloping section of a train service line located in mountainous areas, idling and skidding of the wheels caused by leaves that fall on the railhead in autumn often occurs, and this hinders the scheduled operation of the train. Although counterm

A long-life gear oil for electric railway trains was developed to reduce the workload and cost of gear unit maintenance. A semi-synthetic base oil, a mixture of polyalphaolefin (PAO) and highly purified mineral oil, was used in the developed gear oil

Mineral oil and other lubricants are commonly applied to the gauge corner of high rails to avoid wheel/rail interface wear on railways. Although not directly applied to the top of the rail, these lubricants sometimes end up on this surface, and the r

In this paper, the authors describe experimental investigations of in situ X-ray analysis of interfacial substances between the wheel and the rail. These substances, including iron rust and lubricants, can impact the adhesion coefficient between whee

Flange climb derailments can occur in sharp curves or curves with turnouts within relatively short accumulated running distances subsequent to wheel turning, which indicates that a change in the condition of the turned wheel surface might be inducing

A periodical unevenness of the running surface of rails is formed on ascending slope of submarine railway tunnel. One of the causes has been concluded due to the combination of a low friction and wheel load variation induced by some kinds of iron oxi
