Railway urban turnout is a special track system used to divert a train from a particular direction or a particular track onto other directions or other tracks. It is a structural grillage system that consists of steel rails, points (or called “switches”), crossings, steel plates, rubber pads, insulators, fasteners, screw spikes, beam bearers (either tim- ber, polymer, steel, or concrete), ballast and formation. There are two types of turnouts, a conventional turnout and a tangential turnout. Standard conventional turnouts are designed typically for straight main line track. The combination of switch length, heel angle, and cross rate defines the turnout …

Statistically, the actual loading conditions for railway tracks are rather dynamic and transient. The dynamic loadings due to train and track interactions redistribute from the rails to the rail pad, from the rail pad to the railway sleeper, and from the railway sleeper to the underlying ground. Commonly, railway sleeper in track systems is modeled as a beam on elastic foundation. This study makes use of a calibrated finite element model of railway sleepers in a track system, in order to investigate the resonant frequencies and associated mode shapes of railway components in interspersed track systems. The numerical model takes …

This presentation was invited by Engineers Australia to discuss the importance of railway experience in Japan. Abstract: Rail transport has become one of the most desirable and environmental-friendly means for mass transportation, especially when the up-and-coming peak oil crisis has threatened and discredited many other modes of transport (including traditional car vehicles, trucks, and air planes) from being economical, efficient and sustainable. In this presentation, the modern rail systems in Japan, which cover metro, local and high speed rails, will be discussed together with the infrastructure development, network strategy, ticketing and sources of revenues. Because Japan is the pioneer of …
