Ballast often consists of loose stones that help transfer the load to the underlying foundation. The ties "float" on the ballast and the weight of the track keeps them stabilized. When rail workers are laying train tracks, they often use a flat-bottom steel rail that resembles the steel I-...
By using steel wheels on a steel track, the amount of deformation is minimized, which reduces the rolling resistance. In fact, a train is about the most efficient way to move heavy goods. The downside of using steel wheels is that they don't have much traction. In the next section, we...
the Shinkansen is forced to speed past one urban area after another, thus requiring exceptional noise-abatement measures, from sound barriers to ballast mats.23 As Okada characteristically comments, "When you ride a Shinkansen for the first time, you are surprised by the rows of houses continuing...
