Some trains could continue to face disruption as the hot weather can hit the infrastructure, like overhead lines and even cause rails to buckle.

At London Euston, trains are disrupted until the end of the day after a points failure is blocking some lines.

Avanti West Coast, London Northwestern Railway and Southern services are impacted until the end of the day, National Rail warned.

Fewer Overground trains will run between Stratford and Richmond and Clapham Junction for the rest of the day because of a shortage of train crew.

How to stay cool in hot weather

If you have to travel on the Tube, train or by road this week, have plenty of water at hand and dress in cool, loose-fitting clothing if possible.

Reaching for a sip of water in any weather is not a bad idea, but doctors have recommended one surprising everyday drink in a heatwave.

On the Tube, your best hope is an Underground line with air conditioning.
