Tube Drivers’ Strike Shuts Key London Underground Lines, Disrupting Heathrow Access
Commuters and international travellers faced major disruption this morning (21 April) as drivers belonging to the RMT union began a 24-hour walk-out across the London Underground network. Transport for London (TfL) warned that **no trains will operate on the Piccadilly or Circle lines**, while the Central and Metropolitan lines are partially suspended between key interchange stations. A second 24-hour stoppage is scheduled to start at midday on Thursday, 23 April. For global mobility managers the timing could hardly be worse.

VisaHQ can ease at least one headache: its platform allows travellers and mobility coordinators to secure visas or travel authorisations online in minutes, preventing last-minute paperwork issues from piling onto transport delays.

The Piccadilly line is the only Tube service to Heathrow Terminals 2–5; closure forces passengers onto slower and costlier alternatives such as the Heathrow Express or road transfers, adding up to 90 minutes to journey times in rush hour. Business travellers connecting to early-morning flights were advised to leave “much earlier than normal or book overnight airport hotels,” TfL said. Unions are protesting roster changes and what they describe as “erosion of work-life balance”. TfL counters that modernisation is necessary to close a £740 million post-pandemic funding gap. Estimates from the London Chamber of Commerce suggest each strike day costs the capital’s economy £105 million in lost productivity and visitor spend. Multinational companies with London headquarters activated contingency plans: several relocated client meetings online, while a Canary Wharf bank charter-hired coaches to ferry staff from major rail hubs. Mobility teams should update travel policies to allow expense claims for alternative rail or taxi services during the strike window. Travellers transiting via Heathrow should also monitor separate industrial action on the London Underground Windrush (Overground) line on 24 April and planned air-traffic-control stoppages in Spain, which could compound delays. TfL says normal Tube service should resume by Friday morning if no further action is called.
