More than a dozen train companies are urging Britons not to travel early next week as the UK’s first red extreme heat warning goes into effect.
A total of 21 operators – ranging from Transport in front of Wales and Gatwick Express to the Transpennine Express and Southern – said they will have a slower service on Mondays and Tuesdays National Railways speed limits introduced on its network.
Speed limits are used by train companies during periods of hot weather to prevent damage to the track and to prevent the rails from bending.
There are also cancellations as temperatures in some areas of England.
Amber and red extreme heat warnings have been implemented for the duration across the country.
Those who must travel are encouraged to check their journeys on the National Rail website before departing and bring water with you to stay hydrated.
Refunds are offered to those who are not traveling but have already purchased tickets.
Transport for London chief operating officer Andy Lord said London’s rail network will also have limited service on Monday and Tuesday.
He told LBC: “We advise all our customers to travel alone if their travel is essential, to ensure they stay hydrated and have water with them when they need to travel.
“Check them before they travel, because travel times are extended.
“We will have fewer services on the TFL network because of the security restrictions we have to put in place because of the heat.”
The AA, meanwhile, warned of road melting and tire bursting early next week during the heat wave.
Some local authorities have sent the gritting trucks to spread sand on roads to try to prevent the road surface from melting, the association said.
The AA and North West Ambulance Service have advised that there is a greater risk of tire blowouts in extreme temperatures and have suggested drivers check their tire pressure – when the tire is cold – before traveling.
They have also urged people to drive earlier in the day to avoid overheating the engines.
Edmund King, AA president, said: “The extreme temperatures can be dangerous if you are unlucky or get stuck in traffic jams. Make sure you have enough fuel or electrical charge to run your air conditioner. The heat wave can cause significant problems for many older vehicles without air conditioning or recent maintenance, overheating both the car and its occupants. Driving outside the hottest part of the day is recommended.
“Bring plenty of water – at least one liter per person traveling. Keeping yourself and other occupants hydrated can help lower body temperature in hot weather. Should the worst happen, you can provide yourself and those around you with cool water while you wait for help to arrive.”
