A major milestone in the Midland Main Line Electrification Programme has been achieved, with the 23-mile stretch between Kettering and Wigston now officially certified as safe and ready for electric train operation.
The Office of Rail and Road (ORR) has granted the Authorisation to Place into Service (APiS) for the newly electrified section, marking a significant step forward in the UK’s journey to deliver a greener, faster, and more efficient railway. The section includes a new substation at Braybrooke, which will provide additional power and resilience to support the expanded electric network.
The route was energised in summer 2024, followed by a comprehensive period of testing and data collection to demonstrate its readiness for passenger and freight services. The successful delivery comes on time and under budget, making it a standout achievement in the Government-backed push to decarbonise the railway network as part of its 2050 net zero target.
Cutting-edge technology avoids disruption
One of the key innovations used in the project is voltage controlled clearance (VCC) – a technology that allows overhead lines to pass safely under existing bridges and structures without requiring major reconstructions. This method was applied to seven bridges and four signal gantries, eliminating the need for road closures and extensive civil engineering works.
“This is a huge milestone for the Midland Main Line Electrification Programme,” said Jorge Roque, Network Rail’s Senior Programme Integration Manager. “The use of VCC on this Kettering to Wigston section has saved time, money and avoided lengthy road closures. Where it can be used, it’s a much better solution for residents living nearby, and for this project it reduced more complex interventions such as bridge reconstructions.”
Sustainability and biodiversity benefits
In addition to helping lower carbon emissions, electric trains will also reduce noise and air pollution for passengers and residents living near the line. Network Rail and its delivery partners also achieved a 12% increase in biodiversity along the route, enhancing natural habitats and improving the environmental legacy of the project.
The Kettering to Wigston milestone builds on the previously electrified section between London and Corby, bringing the overall vision of a fully electric Midland Main Line one step closer to reality.
Electric train services are expected to commence on the newly authorised section in the near future, with passengers set to benefit from quieter, smoother, and more sustainable travel.
