Climate change is already hitting over the ways we get around and the bosses of our transport networks are reacting to keep things running smoothly.

Last summer’s heatwaves caused widespread train cancellations, caused by issues including buckled rails and fallen overhead power lines.

Railway tracks are engineered to cope with a certain range of temperatures, but when it gets very hot they can bend. When overhead power lines sag in the heat, they can get snagged in train equipment and be pulled down.

Hot, dry weather followed by heavy rain can trigger landslips, or flash flooding.

Network Rail, which is responsible for maintaining thousands of miles of railway across Britain, is trying to adapt.
