London commuters are facing the biggest Tube and rail strike in 30 years this Tuesday morning.
Thousands of members of the Rail, Maritime and Transport union at Network Rail and 13 train operators are to go on a strike action today, Thursday and Saturday.
This will be the biggest outbreak of industrial action on the railways for a generation.
Just one in five trains are expected to be running, primarily on main lines and only for around 11 hours.
It coincides with the fourth network-wide strike this year on the London Underground.
Bakerloo, Central, Circle, District, Hammersmith & City, Jubilee, Metropolitan and London tram lines had good services this morning while the Northern line, DLR and London Overground were part suspended. The Victoria and Waterloo & City line were suspended.
