The author suggests that under ground railways are an excellent means of transport because .
British towns suffer from the same traffic congestion,
noise and polluting fumes as all towns in the western
world, but as yet only London, Newcastle, Glasgow
and to a small extent Liverpool, have useful railways
going underground through the central areas.
Elsewhere there are plans for building underground
railways but they have little hope of making any
progress with them so long as public expenditure is
restricted. In general, the north has better public
transport than the south, with cheap and frequent bus
services using better roads shared with fewer cars.
