Abstract:

In the US, increasing passenger speeds to improve trip time

usually involves increasing speeds through curves. Increasing

speeds through curves will increase the lateral force exerted on

track during curving, thus requiring more intensive track

maintenance to maintain safety. These issues and other

performance requirements including ride quality and vehicle

stability, can be addressed through careful track design.

Existing high-speed rail equipment, and in particular their

bogies, are better suited to track conditions in Europe or Japan,

in which premium tracks with little curvature are dedicated for

high-speed service.

The Federal Railroad Administration has been conducting

parametric simulation studies that examine the performance of

rail vehicles at high speeds (greater than 90 mph) and at high

cant deficiency (greater than 5 inches). The purpose of these

analyses is to evaluate the performance of representative

vehicle designs subject to different combinations of track

geometry variations, such as short warp and alinement.
