Passengers using trains are being urged not to travel during the heatwave, while motorists are being asked to ensure their cars are well prepared. Train companies including Northern and Transpennine Express have said passengers should only travel if their journeys are absolutely necessary.
Speed restrictions are expected to be in force, to avoid causing damage to the tracks and to prevent rails from buckling, while some cancellations are expected. The AA has warned that roads could melt and tyres may burst with an increase risk of blowouts during the extreme heat.
Train companies including Northern, Transpennine Express and Avanti West Coast have said customers can defer their journeys, or can request a full refund. Customers are being advised to check their journeys on the National Rail website before leaving home.
