RELATIONSHIP BETWEEN RAIL SHELLINGS AND TRACK SURROUNDINGS

Recently, rail shellings that are a kind of rolling contact fatigue failure are causing us considerable cost for rail renewal on Shinkansen lines. To cope with this situation a clarification of rail shelling incidence mechanism has been an urgent demand. But we have yet no effective countermeasures available for preventing rail shellings. We can mainly identify two types of shellings, i.e., running surface shellings and gauge corner shellings. On the Shinkansen lines the former is posing a problem. In the first step to establish a countermeasure against rail shellings, we have conducted a statistical analysis of rail shellings using the rail management unit of SMIS (Shinkansen Management Information System) on Tokaido and Sanyo Shinkansen lines and made clear the relationship between the incidence of running surface shellings and track surroundings. Thus we could reveal to a certain extent the incidence tendencies of running surface shellings under specific track conditions.
