Translink Rail Decarbonisation

Northern Ireland’s (NI) transport is at a critical juncture, facing the pressing challenge of reducing its carbon footprint. Transport is the second-largest contributor to domestic greenhouse gas emissions, accounting for 17% of total emissions in 2021, the need for transformative change is evident. Although NI has reduced its carbon emissions by 23% since 1990 there has been an increase in transport emissions during this period.

In response to this environmental imperative, the Climate Change Act (NI) 2022 has set ambitious targets, including a net-zero greenhouse gas emissions goal by 2050, with interim targets such as a minimum 48% reduction in net emissions by 2030.

Translink, with its visionary 'Better.Connected' and 'Climate Positive' strategies, is a pivotal player in this crucial transition. The proposals to decarbonise the rail network align seamlessly with recent Northern Ireland government department strategies. These strategies, including the Draft Programme for Government, Green Growth Strategy, planning for the Future of Transport report, and Active Travel and Modal Shift report, collectively pave the way for a sustainable and eco-friendly future.

As NI charts its course towards a greener tomorrow, Translink is committed to championing the change. The alignment of strategies demonstrates a collective determination to create a more sustainable, resilient, and environmentally conscious transportation system. Together, we move towards a future where efficient, low-emission rail networks play a central role in achieving Northern Ireland's ambitious climate goals.

Rail Electrification

The Facts*

More Affordable – Over a 30-year vehicle life, the total purchase, maintenance, and traction energy costs of electric trains are £2-3 million per vehicle less than diesel or hybrid equivalents. Electric railways (including electrification costs) are cheaper over their working lives than any other form of traction.

Reduced Journey Times and Increased Network Capacity – Electric trains can accelerate faster than diesel trains and achieve higher line speeds than hydrogen and battery only trains. This enhanced performance will make rail travel more attractive and encourage modal shift.

More Reliable – Electric long distance and suburban trains are respectively 40% and 300% more reliable than diesel trains. This makes an electric railway more reliable than a diesel one despite the occasional overhead line fault.

More Energy Efficient – Electric trains draw energy directly from the grid to power their electric motors and therefore no not suffer from conversion losses and benefit from regenerative braking. Electric trains are almost three times more efficient than diesel or hydrogen.

A Proven Technology – Electric railway technology is well established. Electric trains are lighter, quieter, simpler and cheaper to build, with no inbuilt power plant, far fewer moving parts, and a mature competitive market.
