There is set to be more transport misery for millions with some rail passengers already being urged not to travel by train next week.
Britain’s biggest rail strike for more than 30 years is set to spark six days of chaos amid warnings of a "summer of discontent".
Thousands more workers at Network Rail are to be balloted for strikes in escalating disputes over pay, jobs and conditions, the TSSA union have announced.
It's the largest walk out for years and already a number of lines have been confirmed as being closed. Just one in five services are expected to run on next week’s three days of strikes - Tuesday, Thursday and Saturday -and six lines will be completely closed.
Network Rail have already said there would also be no passenger services to locations including Bournemouth, Swansea, Holyhead, Chester and Blackpool. There will also be no passenger trains running north from Glasgow or Edinburgh.
Where limited services are running, they will mostly start at around 7.30am and finish by 6.30pm on strikes days.
But many commuters are still in limbo as the strike threatens to bring the country’s rail network to a virtual standstill.
Here is exactly what the train companies are saying.
