Several central London stations closed temporarily to manage passenger flow and reduce heat exposure. Oxford Circus, Bank, and King’s Cross St. Pancras were among those affected, with TfL directing commuters to alternative routes. No injuries were reported, but passengers described crowded platforms and long queues for replacement buses.

A TfL spokesperson said the closures were a precautionary measure. "We are monitoring temperatures across the network and taking steps to ensure passenger safety," the spokesperson told *This Is Local London*. "We advise customers to carry water and plan their journeys in advance."

TfL has not indicated whether it will offer compensation for the delays. The operator’s standard policy covers refunds only for delays exceeding 15 minutes on contactless or Oyster payments, but this does not apply to widespread disruptions caused by extreme weather. Passengers seeking refunds must submit claims individually through TfL’s website.

The Met Office issued an amber heat warning for London on 13 August, forecasting temperatures of up to 37°C. The warning remained in place until 19:00 that evening. TfL said it had deployed additional staff at key stations to assist passengers and provide water where possible.

What happens next

TfL has not scheduled a review of the disruptions but will continue to monitor weather forecasts. The operator advises passengers to check service updates via its website or the TfL Go app before travelling. No further closures have been announced, but TfL warned that high temperatures could cause further delays if the heatwave persists.
