What an irony. Thousands travelling to the COP26 climate conference in Glasgow were stranded in London after the two rail lines to Scotland were closed by severe weather. Many took flights instead.

Trains have a vital role to play if we are to tackle the climate crisis. As Clare Foges explained in an excellent column in The Times (Trains are key to getting net zero on track) rail travel creates 14 grams of CO2 emissions per passenger mile compared with 158 grams by car and 285 by plane. Yet Britain’s railways and governments seem to do everything in their power to encourage us to take more polluting forms of transport.

Cost

Travelling by train in Britain is eye-wateringly expensive. A Which? survey, quoted by Foges, found that domestic flights are typically half the price of the competing rail ticket, yet six times worse for carbon emissions. I’d love to travel by train more often, but even for one person the cost is punitive. If you’re travelling as a family, you may need to take out a second mortgage. Saving the planet? All the odds are stacked against us. Esoecially as the UK government has just announced a cut in the tax payable on domestic flights, just days before COP26 began. Madness.
