Scotland’s Railway Gets Ready For Summer Heat

Published on : Thursday, June 27, 2019

Network RailEngineers across Scotland’s Railway are preparing to deal with the hot weather and keep passengers moving if temperatures soar in the days ahead.

 

 

Network Rail engineers will carry out additional track inspections to check for heat-related problems while at some locations special remote monitoring equipment has been deployed to help spot rails which are becoming too hot.

 

 

Our engineers have also been preparing in advance – stressing sections of track (artificially stretching the rails) in known hot-spot areas to help them cope with sudden rises in temperature and painting rails white at key locations to help reflect the sun and keep them up to 10°C cooler.

 

 

During sustained hot spells, rails in direct sunshine can be as much as 20°C hotter than air temperature and expand as they get warmer – sometimes causing them to curve or buckle.

 

 

If rail temperatures in an area do rise significantly, localised speed restrictions may be put in place in some locations to slow trains down and reduce the amount of force being placed on the rails.

 

 

High temperatures can also affect overhead power lines, causing the metal wires to expand and sag meaning trains have to slow down when travelling beneath them.

 

 

Liam Sumpter, Chief Operating Officer for Network Rail Scotland, said: “Hot weather can create real challenges for the railway causing rails to expand and buckle, overhead lines to sag and surrounding land to dry out making our tracks more susceptible to flooding.

 

 

“Every year we invest millions across the country to prepare Scotland’s Railway for summer and to keep our passengers on the move.

 

 

“Our engineers will be out on the network in the coming days, monitoring rail temperatures and working hard to make sure we manage any potential issues.”
