Line 2:
Line 2: − The operation of trains can be much more efficient than road vehicles, as [[steel]] wheels on steel rails produces much less [[friction]] than rubber tyres on roads.+ −
rewrote second paragraph.
Trains run on [[railway track|tracks]] which limits their range, but as the tracks are usually on their own right of way, they avoid the traffic conditions that are common on roadways.

Trains generally don't have the same weight limitations as road vehicles, because they use steel wheels on steel rails. As a result, they can be made to operate more economically, including, in the case of electric trains, not having to carry around a power generation source and fuel. However, because steel wheels on steel rails generate much less friction than rubber tires on concrete, stopping distances for a train are longer than those for other vehicles and can exceed one mile.
