How the weather affects the railway
Find out how weather conditions can cause delays, and see the steps we take to minimise disruptions together with Network Rail
The hot weather can also affect the rails, which can expand, bend and even break in the heat.
We sometimes have to slow down trains to reduce pressure on parts of the line, which can disrupt services.
What we’re doing: Network Rail is on the case, and regularly repairs rails before the start of summer.
Can’t stand the rain? Getting soggy or soaked to the skin is bad enough, but heavy rain can also lead to flooding and delays.
Flood water can damage equipment and cut power to the train, or wash away ballast (crushed stone) and weaken the track.
What we’re doing: Network Rail has flood defence teams and pumping stations ready to respond to any flood warnings. It has a programme of works aimed at flood prevention, for example by clearing drainage ditches and lifting up low-lying sections of track at risk from flooding.
What we’re doing: We’re moving towards a new signalling system for inside the train cab, so our drivers won’t have to rely so much on outside signals.
Strong winds can blow branches, trees and debris onto the train track and pull down overhead power lines.
What we’re doing: Network Rail teams regularly inspect and clear the side of the track. And they’re reducing the gaps between the supports for overhead power lines in windy areas.
While it’s very hot it’s worth carrying a bottle of water around with you when you travel.
If the heat gets to you, ask us for help at the station.
What we’re doing: Luckily, most our trains have air conditioning. We’re also bringing in brand new air-conditioned trains on more of our routes over the next two years.
We work very closely with Network Rail to minimise the impact seasonal weather has on your train service. Network Rail, who own and maintain the track, signalling equipment and power supplies have special rail cleaning trains which run every night in autumn and winter cleaning the tracks. They also remotely monitor the temperatures of their equipment and have several Snow and Ice Treatment trains.
