London Underground

The London Underground, also casually known as the Tube, was an underground network of rail transportation in England's capital city, London.

Day 9
Jack Bauer pursued Simone Al-Harazi on the tube, who travelled on the Northern Line from Kennington Station to Charing Cross Station (via Waterloo). Simone cut herself and told passers by that Jack was attacking her as a means to escape. Jack managed to follow her out of the station, but lost her as she snuck out a service entrance that an Underground employee was working near.

Northern line

 * Neasden Station
 * Kennington Station
 * Waterloo Station
 * Charing Cross Station

Background information and notes

 * The voice announcing that the train was arriving to Waterloo station, and that it was a train to Neasden, is not the actual voice that is used on the London Underground.
 * The Northern Line does not go to Neasden; in fact Neasden is on the Jubilee line.
