There are three periods of industrial action confirmed to be taking place, with different impacts on different days:

1. A nationwide ban on overtime called by ASLEF between Monday 17 and Saturday 22 July
2. A nationwide RMT strike for Thursday 20, Saturday 22 and Saturday 29 July
3. Separate RMT and ASLEF strike action between Sunday 23 July to Friday 28 July by London Underground (LU) staff, which may affect some of our services.

Given the overlapping sets of industrial action, the impacts on train services will vary on different days. We know that this will be inconvenient and difficult for customers, which is why we are strongly urging all customers to check every journey, every day, throughout this period.

The table below shows dates affected by industrial action, a high-level overview of the impacts on services and the expected update for journey planners:
