(Bloomberg) -- British train drivers are set to go on strike from the beginning of February with the first week alone hit by two-day nationwide action and a weekend walkout on a London Underground line.

The strike action on the network is likely to cause major travel disruption. The government is expected to unveil anti-strike legislation in the coming days in a bid to prevent the full stoppage of rail services among other essential sectors.

Here are the planned strike dates for national train and London Tube services.
