Railing against roads

  • 29/09/1996

Railing against roads Rail, as a medium of transport, is often much more energy-efficient and less polluting per tonne- or passenger-km than automobiles.

It can almost always expand its capacity with little further pre-emption of space. Two sets of rail tracks can carry the same number of people as 16 lanes of highway, taking only 15 metres (m) of right-of-way as compared with 122 m for the equivalent highway. Improved train control technologies can triple track capacities. Unlike highways, which need median strips, shoulders and buffers, new tracks can usually be fitted into existing rights-of-way.

Expanding rail networks can make expensive new airports unnecessary.

It has the potential to unify cities due to the central location of rail stations, rather than damaging them as suburban malls and highways do.

Transport is much safer by rail.
