London Underground workers set for strike action in dispute over pay on new all-night service

London commuters face a particularly disruptive a strike on London's Underground in a dispute about how much workers will be paid when the service goes to 24 hours on some lines later this year.

Transport for London says so many drivers are expected to participate that it will be impossible to run any part of the service during the action which starts on Wednesday and will last all day Thursday. In past strikes, management managed to keep a few lines running.

TFL warned customers to avoid travel in the hours before the strike begins, as the system will be exceptionally busy.

Troubles are set to be further exacerbated by a separate strike by employees of First Great Western, disrupting rail services in and out of West London's Paddington Station.
