Greater Anglia and Network Rail are taking action to minimise disruption to rail passengers during hot weather.

East Anglia is seeing hotter summers and when the air temperature is 30C, the temperature on the rail can be up to 20C higher.

This can cause a type of signalling problem called a track circuit failure and in extreme cases can cause a buckled rail.

To tackle this issue, Network Rail has painted rails white at critical points around the network. This paint prevents the rail absorbing as much heat and can keep it up to 10C cooler than an unpainted rail.

Greater Anglia's managing director, Jamie Burles, said: 'We are acutely aware of the frustration and inconvenience felt by our passengers when things go wrong, so we are pleased to be taking action in partnership with Network Rail, making additional preparations to make travelling more comfortable in hot weather.'
