RailDecarb21 is RIA's campaign to highlight the work rail is ready to deliver to decarbonise and support the UK Government in achieving its targets of removing all diesel-only trains off the network by 2040, and reaching Net Zero by 2050.

The campaign is calling for a specific commitment to decarbonise the rail network from Government, through further electrification work and fleet orders of low carbon, self-powered rolling stock, ahead of the UN Climate Change Conference (COP26) taking place in Glasgow in November 2021.

About RailDecarb21

Rail is a low carbon mode of transport, contributing just 1.4% of transport emissions despite carrying 10% of all journeys. Rail accounts for only 0.5% of all UK emissions.

Following the Coronavirus pandemic, getting passengers and freight back onto the rail network will ensure our railways continue to support low carbon travel, whilst also creating jobs, investment and economic growth. However, to achieve the UK Government's legal commitment to Net Zero by 2050 and its aim to take all diesel-only trains off the rail network by 2040, further action will be needed.

The interim Traction Decarbonisation Network Strategy (TDNS) published by Network Rail shows that to achieve Net Zero, the 15,400 kilometres of currently unelectrified railway lines in the UK will require decarbonising by:
  • 11,700 kilometres to be electrified;
  • 900 kilometres for hydrogen trains;
  • 400 kilometres using battery trains; and
  • 2,300 kilometres where multiple options are available.

Electrification has a patchy record of delivery. It’s time to invest in a rolling programme which will speed up delivery, drive down costs and hold to account those who do not deliver to time or budget.

We know that the Government is keen to encourage the development of hydrogen power and ask that the decarbonisation plan is flexible enough to include alternative and new technologies. To help, our research and development capabilities must be properly supported and funded.

Decarbonisation of the rail network will therefore involve both further electrification and the introduction of low carbon, self-powered rolling stock, such as battery and hydrogen. Crucially, the UK needs to start decarbonising now, as both infrastructure and rolling stock projects take time to deliver. Trains have an average 30-year life, meaning rolling stock we commission today may still be on the network in 2050. 

In the run up to the UN Climate Change Conference in Glasgow – COP26 – the UK Government has the opportunity to show its leadership on a global stage by taking steps to decarbonise the rail network, creating green jobs and investment in the process.

RIA's Key Asks

38% of the UK rail network is electrified - much less than comparable European countries which are typically 60% or more electrified. Electrified railways have been shown to benefit passengers and the wider travelling public as it is:

  • Better for the environment, with carbon emissions 60% lower than those from diesel trains today and 80% less with the estimated 2040 grid mix; they also produce no air pollutants at the point of use;
  • Quieter, reducing noise pollution for those living and working near the tracks and reduces noise and vibration for passengers;
  • Costs less in the long term when compared to the whole-life costs of diesel services;
  • Improves journey times due to superior braking and acceleration;
  • Is lighter, meaning less wear to the track and therefore less maintenance;
  • Reduces passenger delays, as electric trains are more reliable than diesel trains; and
  • The only decarbonisation technology suitable for freight trains and faster passenger trains (above 100mph).

As shown by RIA’s Electrification Cost Challenge report, electrification in the past has been delivered in peaks and troughs of work, providing the industry with a significant amount of work over a few years, followed by a cliff-edge in activity. This has led to higher costs as the sector is unable to retain the skills and expertise as shown by the cost increases on the Great Western Electrification Programme.

A rolling programme of electrification could reduce costs by up to 50% compared to some past problem projects, as shown by RIA's Electrification Cost Challenge report

 


 

There are parts of the network where electrification will not be a cost-effective solution and where technologies like hydrogen and battery will have a role. The industry has demonstrated its ability to offer these new technologies, with a number of rail suppliers working on low carbon rolling stock solutions.

A fleet order of new rolling stock would stimulate a new industrial sector, creating and retaining jobs and intellectual property in the UK whilst accelerating the decarbonisation of the network and supporting future exports. There is an opportunity for UK rail to become a global leader in battery and hydrogen technologies, with rail demand helping to create the UK market necessary to stimulate growth and kick start the zero carbon economy.
