Abstract:

In Japan theoretical and experimental studies have been conducted since the early 1930s to work out effective measures to maintain lateral track stability. In 1957 the theory of track buckling based on the principle of virtual work was established, which is the basis for current practical measures to ensure lateral track stability. The theory defines the minimum buckling strength, which corresponds to the minimum longitudinal load at which a stable distortion wave can exist. Based on the theory and practical experience, laying and maintenance standards for continuous welded rail (CWR) and joint-gap control methods have so far been established, both of which have effectively contributed to lateral track stability. Recently, it has become necessary to use CWR even on sharp curves and to remove expansion joints in front of and behind a turnout to reduce maintenance. From this point of view, it is important to make clear the cause of track buckling and to understand more clearly the behavior of long welded rail connected to turnouts. The historical background and the current status of the theory and practice of lateral track stability in Japan are described in this paper.
