Commuters travelling through London Waterloo have been warned to expect chaos this evening following a fire at the busy transport hub.
British Transport Police have warned that "services will be severely disrupted this evening", adding that travellers should check wth National Rail and South-West Trains before they set out.
National Rail has also tweeted about the issue, telling travellers their rail tickets will be accepted on "many other train operators and bus operators." Specific information can be found here.
The line-side fire, which began earlier today, has damaged the signalling system and led to track circuit failures on three of the main lines into and out of London Waterloo.
At present (5pm) National Rail is warning of "a large build-up of trains" outside Waterloo, and Network Rail engineering staff will be taking control of platforms 1-9, which could exacerbate the chaos.
The disruption is likely to be extremely severe given the large number of Christmas parties taking place in Waterloo and central London this evening, and the icy weather conditions which have caused scores of Londoners to use public transport rather than walk or cycle.
