London Underground Faces Week-Long Strike Action: Complete Guide to September 2025 Transport Disruption
Major Transport Disruption Hits London
London’s nine-month period of strike-free tube travel is coming to an end as the capital faces its first major Underground disruption of the year.
The RMT union has called for a ‘rolling’ strike action as part of their campaign to secure a reduced working week, in addition to the offered 3.4% pay rise. The union claims that Transport for London (TfL) has ‘refused to engage seriously’ on matters including fatigue management, extreme shift patterns and working conditions.
Strike Timeline and Impact
The industrial action will begin at 6pm on Friday September 5, with different workers walking out on each day until September 11. However, the effect – halted tube trains – will be consistent throughout the period.
Services on every single line on the London Underground will be affected. Although different workers will be walking out on different days, the impact will be similar throughout the week, with no service on Underground lines from Sunday September 7 through Thursday September 11.
Alternative Transport Options
The London Overground lines, National Rail, and London bus services will all continue running as usual during the strikes. However, these services are expected to be significantly busier than normal, and passengers are advised to allow extra time for their journeys.
The Elizabeth line will operate as normal, as it’s technically separate from other tube lines. However, Elizabeth line trains may not stop at certain stations if they are closed as part of the industrial action.
Additional Transport Challenges
The DLR will face separate strike action with no service on Tuesday 9th and Thursday 11th September. While the DLR will run a full service on other days, stations shared with London Underground services may experience disruption. Additionally, First Bus services in west, northwest and southwest London will be affected by separate strike action between Thursday 11th to Sunday 14th September.
An RMT spokesman has stated they remain open to talks and are awaiting a revised offer. The strikes are expected to have a serious impact on London’s businesses and commuters, with the Mayor urging both the RMT and TfL to continue negotiations to resolve the dispute and avoid industrial action.
