The Met Office and Network Rail have signed a deal to help drive forward research into weather and how it affects the railway.

The Memorandum of Understanding will cut the time needed to commission research from months to days, speeding up the vital work Network Rail and the Met Office do to keep passengers moving through extreme weather.

This includes work on probabilistic weather forecasting and understanding the complex links between earthwork failures and rainfall, antecedent soil wetness and geology.

Network Rail’s industry weather response director, Lisa Angus, said: “Extreme weather is one of the biggest challenges facing the railway and one of the major causes of delays to passengers and freight. Science plays a significant role in our response, in particular using the vast amount of data and data processing capacity the Met Office has.

“For example, we are one of the world leaders in understanding the links between rainfall and earthworks, from soil types to rain intensity, and that is thanks to our partnership with the researchers at the Met Office. This MOU will only help us increase our working together and provide a better deal for passengers – and taxpayers.”

Met Office’s director of government and industry relationships, Steven Calder, added: “It’s great to deepen our relationship with Network Rail for the benefit of passengers. It’s only by working together that we can address some of the biggest challenges, and, powered by our weather and climate intelligence, we’ll help give Network Rail the tools, knowledge and expertise it needs to plan effectively for the future.”

Up until now the partners have had an ongoing commercial relationship, despite both being government bodies. Now, thanks to this new agreement, the process of working together, whether to share data, or develop innovative science and research, can be accelerated between the Met Office and Network Rail, streamlining procurement processes under the new agreement.

Along with research into rainfall and earthworks, the partnership has also seen work on helping controllers make decisions on when it is safe to run trains and how fast.

This MOU does not include day-to-day weather forecasting which is supplied to Network Rail by weather firm MetDesk. Those forecasts drive day-to-day operational decisions including the company’s fire risk for each day, and the Convective Alerting Tool, which helps route controls manage the risks caused by heavy rain.
