London 2012 Olympics: travel disruption at key stations Good morning and welcome to today's Olympics live blog. Transport for London and Network Rail are clearly worried about the potential for overcrowding on the transport system during the Olympics and for months have been warning Londoners the Games are coming and encouraging them to make alternative transport plans, such as walking to work. This morning seemed to give a little taste of possible problems to come. Network Rail has been rehearsing its crowd management and queuing system for the Olympics at key stations around the capital: London Bridge, Cannon Street, Victoria, Charing Cross and Waterloo East. Twitter users seem unimpressed - especially those using or trying to use London Bridge. In a separate incident a faulty train on the Northern line at around 8.40am meant platforms became congested and that King's Cross St Pancras was temporarily closed - for 10 minutes, according to Transport for London - causing scenes large crowds to gather in the streets outside the station (see picture above). This seems to have had a knock-on effect at nearby Euston too. Were you at any of these stations this morning? Send me your stories and pictures to paul.owen@guardian.co.uk or @paultowen. Here is what else is coming up today: The Queen is due to view the Olympic flame at Windsor Castle as it makes its way from Oxford to Reading. Royals and commoners, send your photos to paul.owen@guardian.co.uk or @paultowen. The royal party, joined by Locog boss Sebastian Coe, will meet a number of torch-bearers from the 1948 London Games and meet the designers of the current Olympic torch. Sir Roger Bannister, the first man to break the four-minute mile, carried the flame in Oxford today, the scene of his record-breaking run. Jockey Frankie Dettori and Olympic gold medallist Denise Lewis will carry the torch when it reaches Ascot. Five-time Olympic gold-winning rower Sir Steve Redgrave will carry it in a boat in Henley later. A judge is due to rule on whether the Ministry of Defence can place missiles on the roof a London tower block during the Olympics. Bus staff in London have been made an offer for working during the Olympics in a bid to avert the threat of further strikes. London 2012 chairman Sebastian Coe has said David Beckham will be "more than an ambassador" at the Olympics and will perform two distinct roles. Usain Bolt is fit and firing ahead of the Olympics, according to his agent.
