More strikes will affect London's transport network this July.
On Wednesday 27 July, the RMT union will strike across the national rail network; followed by industrial action from members of the ASLEF union on Saturday 30 July.
Although no TfL staff are striking, the District and Bakerloo lines, London Overground, and the Elizabeth line are expected to experience "varying degrees of disruption" on 27 July, says TfL, owing to the fact these lines share sections of track with Network Rail.
Some disruption is expected to continue through to 28 July.
Things get more severe on 30 July, when the London Overground network shuts down entirely (due to strikes from Arriva Rail London, which operates the Overground). There'll be no night Overground on Saturday 30 July or the early hours of Sunday 31 July, either.
Reduced timetables will be also in place across the Elizabeth line on 30 July, with TfL suggesting passengers seek alternative routes. There'll also be no Elizabeth line services between Paddington and Abbey Wood on Saturday 30 July and Sunday 31 July — although that's due to engineering works.
The strikes are over a dispute about pay and working conditions, which the RMT general secretary Mick Lynch has said "will not simply vanish."
