Railway used in mountainous regions, which
uses a toothed pinion running in a toothed
rack to provide traction. The rack usually
runs between the rails. Ordinary wheels lose
their grip even on quite shallow gradients,
but rack railways, like that on Mount Pilatus
in Switzerland, can climb slopes as steep as
1 in 2.1.
