![]() ![]() The hot weather forecast this week means Network Rail has activated its ‘extreme weather action teams’ (EWATs) to ensure passenger safety and that we keep our railway running as reliably as possible. The problem is that if we stressed Britain’s rails to the same degree as those in very hot countries, there would be the risk of increased tension on the rails in the winter. Temperatures have been rising in the UK, particularly in East Anglia, so this may seem like the obvious solution. Why don’t we replace all our rails with ones stressed for higher temperatures? You can see the adjustment weights at the lineside as part of the overhead line system.īeyond the limit of adjustment, the wires sag, causing a risk that a passing train could pull them down. Within a certain limit of expansion, the tension in the wires is automatically adjusted. The overhead line system (pictured) expands in the same way as the track. The need to prevent problems also means there will be fewer trains, but this is better than causing a bigger problem and being unable to run any services. When heat expansion forces are high, trains deliberately slow down to reduce the additional forces they apply to the railway. The higher the speed, the greater the force of a train. The movement of trains also generates forces in the track. Slab tracks costs approximately four times as much to install as standard ballasted track. In some countries the forces generated by temperature variation cannot be contained by sleepers and ballast, and a solid concrete slab is used to contain the higher forces. The mass of the sleepers and ballast are designed to contain these forces and prevent the track from buckling. This generates forces that try to push and pull the railway out of shape. The steel rail on a railway track is a very long piece of metal that can expand or contract significantly in the summer and winter. We do all we can, however, to ensure services continue to run safely and smoothly at times of extreme weather. In Britain, the variations in short-term weather and long-term climate mean that it is neither practical nor cost effective to implement these measures permanently on the British rail network. They may adjust their rails between summer and winter, or have other measures in place to manage the effects over the long term.
