Network Rail is painting tracks white to cool them down because they're 48°C

In a bid to prevent tracks from becoming too hot, Network Rail uses a number of techniques including painting certain parts of the rail white so they absorb less heat.Other methods used by the rail operator include leaving small gaps between rails allowing them to expand safely and closing monitoring temperatures.

Network Rail said the number of passengers using major stations across Britain on Monday was around 20% lower than a week ago. Many operators are running a heavily reduced timetable today and tomorrow, including Avanti West Coast, CrossCountry, Great Northern and Thameslink.LNER is not running any trains from south of York and south of Leeds to London King’s Cross tomorrow.

Kevin Groves, chief spokesperson for Network Rail, said journeys that typically take two hours could take ‘more than four hours’ as emergency measures have been brought in to prevent trains derailing. He told Sky News: ‘Certainly later on today that is a strong possibility, which is why, from about midday today through till 8pm tonight, there will be large swathes of England and Wales that will have emergency heat-related speed restrictions placed on the rail network.’He told BBC Radio 4’s Today programme the return of normal services on Wednesday ‘will depend on the damage that the weather does to the infrastructure’.

This is extremely dangerous, trains will lose traction on a painted surface in the same way gantry cranes do
