Higher temperatures spreading north led to Scotrail on Monday following England and Wales in slowing down trains for safety. Trains across Britain were limited to a 90mph maximum, while on the east coast line linking London, York and Edinburgh the top speed was halved to 60mph.

The east coast line is predicted to experience the hottest temperatures, and some of its infrastructure, including for the wires and track, are more susceptible to damage in heat than other parts of the UK railway. The line will be closed entirely south of Leeds and York on Tuesday.
