SPEED restrictions will be in place in parts across the Greater Anglia network due to the high temperatures this day.

The train operator has warned passengers that trains will be running at a slower speed to "protect the railway infrstructure and keep services running."

A spokesman for Greater Anglia said: "With very high temperatures forecast for the region on Monday June 19, speed restrictions will be introduced on some lines to protect the railway infrastructure and keep services running, but at a slower speed.

"Therefore, Greater Anglia is advising customers to check before they travel.

"During hot weather, Network Rail will sometimes impose speed restrictions to prevent rails from buckling when they get very hot (the lower speeds exert less pressure on the rail) and to protect overhead lines, which may sag during very high temperatures.

"The introduction of speed restrictions has caused changes to our scheduled service. Please check before you travel at www.greateranglia.co.uk or @greateranglia to find out how services are running on these days."

The company has directed customers to Network Rail's explanation of what happens to the rail network gets hot which you can see here.
