Prolonged high temperatures are continuing to cause disruption for travel services across the country, with thunderstorms threatening further problems.

Eurotunnel passengers are still facing delays of up to two hours after Thursday’s soaring temperatures left air conditioning units on carriages unable to cope. The firm made the decision to cancel day trip tickets today to ease queuing and urged customers to arrive no longer than two hours before their scheduled crossing and to bring plenty of water in case of long wait times.

Meanwhile, services on the East Coast mainline have been disrupted after lightning strikes damaged signalling systems. London North Eastern Railway says trains between Leeds and York are facing severe delays until at least the end of service today and services in the Doncaster area may also be affected.

Speed restrictions put in place by Network Rail over fears that tracks may buckle or expand in the heat are still in place across Chiltern Railways, Northern and Greater Anglia services, causing knock-on cancellations due to late-running trains.

Motorists have been warned of potentially dangerous conditions owing to forecasted heavy rainfall, with the Met Office issuing a storm warning until 2345 Friday night. In addition to rain, storms could bring localised flooding, strong winds and hailstones.

Travellers are advised to check current conditions and status updates before departing.
