Reports are coming in tonight of several problems on the Tube network caused by this afternoons storms.
Most seriously, 600 people have been safely evacuated from a Piccadilly Line train, after a landslide caused 'four tonnes of debris' to land on the tracks. The train hit the pile, but no injuries were reported. Needless to say, service is partly suspended on this line - between Northfields and Heathrow.
Meanwhile, the District Line is suspended betwix Turnham Green and Richmond because of a lightening strike at the latter. This is causing severe delays on the rest of the line.
More tomorrow, if these stories develop further.
