Thousands of London commuters have been plunged into travel chaos this morning after a major fire broke out at Vauxhall station. Passengers have been urged to only travel if "absolutely necessary" by South West Trains, whose service is severely disrupted. Commuters were left stranded at stations across the network, with those who did manage to get on a train saying services were "dangerously full". Firefighters were called to the busy travel hub at 2.39am and have been battling the blaze, which has not yet been extinguished, ever since. Trains in and out of Vauxhall and Waterloo have been disrupted as the blaze affected electrical cabling. Power to the tracks has been switched off and passengers have been warned to check the latest travel. South West Trains said it had limited services and asked travellers to use alternative routes to the city. Tickets will be accepted on Southern, Great Western Railway and Transport for London services. The disruption is expected to continue until 10am, with trains to Vauxhall being cancelled, delayed by up to 60 minutes or revised.
