London's Mayor Boris Johnson has boldly claimed the transport system will run perfectly during the Olympics

Boris Johnson has vowed London’s transport system will be “completely perfect” during the Olympics.

There are fears the capital’s roads, railways and Tube lines - which are already operating at maximum capacity - will be unable to cope with the huge increase in demand when the Games begin in 12 months’ time.

But Mayor of London Johnson was confident plans were in place to ensure everything would run like clockwork between July 27 and August 12 next year.

“We need to get London ready, get the transport system completely perfect and we will,” he said.

Minister for sport and the Olympics Hugh Robertson admitted anything but perfection would lead to problems.

“Everybody knows the transport system has to run pretty much perfectly for 16 to 17 days in a year’s time,” he said.

“We’re absolutely focused on this and I’m as confident as I can be that we’ll deliver it.”

Explaining what was being done to achieve that, Mr Robertson said: “First, you put half a billion pounds into upgrading the transport around Stratford, so there’ll be much bigger capacity at Games time.

“Secondly, we’ve laid on a Javelin train, that will go from St Pancras to Stratford to Ebbsfleet and turn around. The journey time for that will be seven minutes.

“There’s then the Olympic Route Network and the transport command management system which will, in layman’s terms, effectively suppress demand to try to get people off the roads.

“Yes, London is crowded, it’s congested, we have to move a lot of people around.

“But then we sort of do this every day of the week - that’s the way London works.

“So we’re not starting from a position where we know nothing about this.”

Mr Johnson added: “We’re in the process of upgrading the Jubilee Line.

“By next year, that’s going to have I think another six trains an hour.

“That would be a much better service taking you through to Stratford from central London.

“The Docklands Light Railway’s got another car on it, the Central line’s been upgraded, you’ve got the amazing new East London line, coming up from Croydon.

“This is one of the best connected railway hubs in the whole of the UK.”

There is also the thorny issue of Olympic lanes, which will see some of London’s roads closed to the public during Games time.

International Olympic Committee president Jacques Rogge insisted they were necessary.

“The Olympic Lanes, let me tell you that it is less than 10% of the London territory that is affected,” Rogge said.

“It is very much needed because, if you don’t have Olympic lanes, the athletes will not be able to perform and will not be able to compete on time.

“The Olympic Games also is for the media, 25,000 media people.

“You cannot go from one competition site to another on public transport and be there on time.”

He added: “Transport is always an issue at every Olympics.

“This is not special to London.

“But always with a good strategy and good planning, we were able to manage it to everyone’s satisfaction.”
