Rail passengers face a third consecutive day of disruption on Thursday because of a strike by train drivers which will again cripple services.
Passengers have been hit by a series of 24-hour walk-outs since Tuesday, May 7, with drivers at 16 rail companies launching a wave of industrial action to disrupt journeys this week.
Drivers belonging to the Aslef union are walking out between Tuesday and Thursday, May 9, in a row running for almost two years.
Major strikes hit commuters on Tuesday and Wednesday, when train operators across the country ground to a halt.
And the action continued on Thursday with LNER, Northern Trains and TransPennine Express drivers striking.
Here is everything you need to know about the National Rail strikes.
When and where will the strikes take place?
Members of Aslef are walking out from Tuesday, May 7 to Thursday, May 9 at different operators and ban overtime for six days from the bank holiday Monday, May 6.
May 7: Drivers will strike at c2c, Greater Anglia, GTR Great Northern Thameslink, Southeastern, Southern, Gatwick Express and South Western Railway.
May 8: There will be rail strikes at Avanti West Coast, Chiltern Railways, CrossCountry, East Midlands Railway, Great Western Railway and West Midlands Trains.

Which train lines will be affected?
On Thursday, May 9:
Members of Aslef at LNER, TransPennine Express and Northern Trains will walk out for the day following similar action over the past two days at other operators.
TransPennine urged people not to attempt to travel as it will not be running any services on its routes.
Disruption is also likely on the day after strike action and services may start later and finish earlier than usual.
Northern said it will also not run any services on Thursday.
LNER will run more than 40 services between London, Edinburgh and West Yorkshire, equivalent to around a quarter of its usual timetable.
