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.
