Travel around London during the Olympic Games looks set to be difficult as the Tube will fail to cope with the extra load of passengers.

The Metro newspaper reported that insiders have admitted that the Tube network will buckle under the extra workload during the Games, turning the capital into a ‘laughing stock’.

One senior London Underground employee said: “It is simply not going to be ready and there is nothing we can do about it. It will not be able to cope with the extra numbers. Trains will break down and lines will be shut. The attitude at London Underground seems to be: ‘Let’s just wait to see what happens – there’s little more we can do now’ .”

The network is expected to hold an extra million passengers each day during the Games in July and August. To add to this, London bus drivers are threatening to take industrial action over the period in a dispute over pay. The drivers, who work for 21 privately-run bus companies, are asking for bonuses for driving more crowded buses for the duration of the Games. 94% of members of Unite Union voted to strike, however the ballot turnout was only 38% which could indicate that the action does not hold much support.

Transport for London is urging commuters to leave work later or find alternative ways of getting home to ease the pressure on the Underground. A spokesman said: “We’re confident but not complacent.”
