Scotland’s Railway is on track to be Net Zero by the Scottish Government’s 2035 target for rail, thanks to its increasing efforts to help fight climate change.
ScotRail has reduced its carbon footprint by 38 per cent since 2014, including a 30,002-tonne saving in 2020. That’s the equivalent of over two million car journeys between Edinburgh and Glasgow or equivalent to the annual carbon footprint produced from 2,308 Scots over a 12-month period.
Scotland’s Railway is a rapidly evolving success story, with more than 76 per cent of passenger and 45 per cent of freight journeys already electrified.
And it is estimated that travellers can reduce the CO2 output from their journey by roughly 70 per cent by switching from road to rail. This increases to around 90 per cent on an electric train journey.
Speaking at a New York Times Climate Hub event at SWG3 in Glasgow yesterday (Wednesday 10 November), Alex Hynes, Scotland’s Railway Managing Director, outlined his vision and plans for a net zero carbon future on Scotland’s Railway.
All diesel trains will be taken out of service over the next 15 years through the decarbonisation of the rail infrastructure. There are projects currently underway to do this on lines around Glasgow such as East Kilbride and Barrhead, creating more sustainable journeys and stations.
Between 2014 and 2019 Scotland’s Railway electrified 325km of the country’s central railway network. This investment supported the introduction of a new £370m fleet of 70 faster, greener, modern electric trains, with more capacity for customers.
However, the difficulties posed in the route clearance of structures to ensure there is sufficient headroom to run the electric wires under bridges and through tunnels is a major challenge in decarbonising the railway through electrification.
Around 90 structures needed to be rebuilt or significantly altered to support electrification works across central Scotland, including bespoke systems introduced through Winchburgh and Queen Street tunnels.
On the rural Scottish routes where electrification may not be possible, Scotland’s Railway is developing hydrogen and battery train solutions.
ScotRail has also introduced innovations such as the use of a fuel additive that is estimated to deliver a three per cent reduction in fleet diesel usage with further associated savings in carbon and nitrous oxides.
The train operator continues to invest in energy efficient technologies and plans to deliver Scotland’s first net zero carbon station at Falkirk High.
ScotRail’s Decarbonisation Action Plan aims to eliminate carbon emissions completely by 2035.
Alex Hynes, Scotland’s Railway Managing Director, said:
“In recent years a huge amount of progress has been made in a short timeframe, making the transition from road to rail easier as every milestone is reached.
“We have identified electrification and the transition from diesel to alternative traction such as hydrogen and battery trains as the key to achieving zero CO2 emissions on Scotland’s Railway by 2035, and we are pushing ahead with big investment to make that a reality.
“Rail is already the most sustainable mode of public transport, contributing only one per cent of Scotland’s overall transport carbon emissions but, there’s no doubt a cleaner and greener network is something we should all be working towards.
“And it’s not all about trains. We have to develop a transport system for everyone. One that integrates walking, cycling, wheeling, buses, and electric cars with our stations.
“We’ll be looking to further develop our partnerships with organisations that link modes of transport together like local authorities, Regional Transport Partnerships, bus companies and bike hire firms to make it much easier for people to choose an integrated sustainable journey."
