A force to be reckoned with

Arcadis, Linxon and SSE Contracting come together to power Britain’s railways

We are entering a time of great change for the railways. COVID-19 apart, the industry is on a journey to a cleaner, greener future. Network Rail is working towards achieving net zero carbon emissions by 2050 (2045 in Scotland) and delivering continual improvements to air quality.

Late last year, the owner and infrastructure manager of most of the railway network in Great Britain has become the first in the world to set the most ambitious science-based targets to limit global warming – cutting emissions which limit warming to 1.5°C.


At the heart of those ambitions, is Network Rail’s proposals for 12,000 kilometres of electrification by 2050, including hydrogen and battery technology, all outlined in the Traction Decarbonisation Network Strategy.

Work is also well underway on the construction of HS2 which, once complete, will deliver low carbon journeys and cut carbon emissions from other forms of transport.
In the future, trains will be highly energy efficient and entirely powered by a grid that uses increasing amounts of energy from zero carbon sources.

With the plans and targets now in place, attention is turning to delivery; something that must be done safely, efficiently and collaboratively, with millions of passenger journeys to depend on the systems put in place.

In a unique move for the industry, and a bid to offer that one-stop solution, a powerful consortium involving Arcadis, Linxon and SSE Contracting has been established to power up a greener and more effective railway, delivering the HV solution as one.

Robin Tunley, SSE Contracting’s Programme Director Major Projects, said: “A safe and reliable high voltage power supply is a vital part of the UK railways plans for a cleaner, greener future and keeping the network running safely and reliably.

“Collectively we’ve seen an opportunity to come together as one to create strength in unity and a powerful consortium with complimentary skills which can only be good for the industry.

“As Arcadis, Linxon and SSE Contracting we offer different but complementary services, and we all share the same vision in playing our part to work together to power the railways in an efficient and safe manner and in doing so tackling climate change.”

The opportunities
Rail is already the cleanest and greenest mode for transporting large numbers of people and goods, but as an industry we are committed to cutting carbon footprints even further.

As well as the initiatives by Network Rail, there is also the opportunities created through HS2, that recently started the search for specialist contractors to deliver the high voltage power supply systems that will transfer electricity to the UK’s new high speed rail link and enable millions of people to enjoy low carbon journeys.

The winner of the contract will be responsible for the design as well as manufacture, supply, installation, testing, commissioning and maintenance of the HV power supply systems. 

Approximately 50 traction sub-stations will be built alongside the line between London and Crewe in order to deliver power from the National Grid to the trains. There is also HydroFLEX, the first-ever hydrogen-powered train, which recently ran on the UK mainline. Unlike diesel trains, hydrogen-powered trains do not emit harmful gases, instead using hydrogen and oxygen to produce electricity, water and heat.

Nick Lawton, Programme Director at Arcadis, said: “There are some really exciting opportunities in the market and we hope that by working together we can offer that one-stop solution, and that through our combined skills and experience we can support our clients in ensuring the rail network continues to run safely and reliably.

“We strongly believe that as a consortium we can ensure that we can deliver the best quality and value when it comes to HV power for the railways.”

Robin Tunley said: “At a time when the environment is at the top of the agenda, we will work together to create a full life VFM and carbon impact value, that can prevail on the HV distribution system.

“Together we can deploy assets to generate revenue, reduce cost price of infrastructure, contribute to net zero carbon, provide employment and upskill local communities and share additional upside where applicable.”
