• Germany, France, Switzerland and Austria bring back routes for night trains.
  • Traveling by rail emits much less carbon per kilometre than going by air or road.
  • 2021 is set to be designated European Year of Rail.

There’s something about long-distance train travel that stirs the soul. It conjures up the romance of a bygone era, full of opportunities for adventure, mystery, and even love. But in Europe, waking up as your train pulls into a foreign capital isn’t a relic of the past, but a sign of the future.

National rail operators in four countries – Germany, France, Austria and Switzerland – have announced plans to revive the continent’s network of night trains. Routes from Vienna to Munich and on to Paris, and Zurich to Amsterdam via Cologne will be re-established in 2021. Further routes – linking Berlin, Brussels, Rome and even Barcelona – are planned within the next few years, reviving services that were declining in recent decades.

The revival in transcontinental sleeper trains has been prompted by a change of heart by Germany’s rail operator Deutsche Bahn, which had decided overnight services weren’t popular enough, and cost too much money. Now cross-border cooperation is seen as the key to making routes economically viable.

“Europe’s leading railways are pooling their forces for the night train,” said Deutsche Bahn’s CEO Richard Lutz. “The night train is a business between partners. If every railway were to do ‘a little night train’, nobody would be of any help. The solution is a clear division of labour, embedded in real team play.”

Boosting rail travel is increasingly being seen as essential to bring down carbon emissions from the transport sector, as the chart below demonstrates.

Long distance trains have lower carbon footprints than most other forms of transport, and emit tiny amounts of carbon per kilometre compared to air travel.


What is the World Economic Forum doing to reduce aviation's carbon footprint?

As other sectors proceed to decarbonize, the aviation sector could account for a much higher share of global greenhouse gas emissions by mid-century than its 2%-3% share today.

Sustainable aviation fuels (SAF) can reduce the life-cycle carbon footprint of aviation fuel by up to 80%, but they currently make up less than 0.1% of total aviation fuel consumption. Enabling a shift from fossil fuels to SAFs will require a significant increase in production, which is a costly investment.

The Forum’s Clean Skies for Tomorrow (CST) Coalition is a global initiative driving the transition to sustainable aviation fuels as part of the aviation industry’s ambitious efforts to achieve carbon-neutral flying.

The coalition brings together government leaders, climate experts and CEOs from aviation, energy, finance and other sectors who agree on the urgent need to help the aviation industry reach net-zero carbon emissions by 2050.

The coalition aims to advance the commercial scale of viable production of sustainable low-carbon aviation fuels (bio and synthetic) for broad adoption in the industry by 2030. Initiatives include a mechanism for aggregating demand for carbon-neutral flying, a co-investment vehicle and geographically specific value-chain industry blueprints.

The boom in fast, cheap and convenient short-haul air routes was the main reason behind the precipitous drop in long-distance rail. But growing environmental awareness has changed the equation. This has resulted in the phenomenon of “flight-shaming”, which gained global attention when climate change campaigner Greta Thunberg chose to take the train to the World Economic Forum Annual Meeting in Davos in 2019, rather than fly.

Many European railways have seen something of a renaissance, with passenger numbers going up and rail-friendly policies being adopted by the EU. This year is being designated the “European Year of Rail” as part of a push to promote rail travel as an environmentally friendly alternative not just for would-be airline passengers, but to hauliers who transport most of their freight by road.

“Rail is the answer to many critical issues in the area of mobility, such as climate neutrality, energy efficiency, crisis resilience and safety,” says Germany’s transport minister Andreas Scheuer. “The Year of Rail aims to give a boost to the sector and to encourage more tourists, business people and manufacturers to choose the train.”

As international travel recovers from the devastating restrictions of the COVID-19 pandemic, passengers will demand ever greater choice. For many, the hard-hit airline industry, which is working towards its own ambitious goals to reduce its carbon footprint, will still offer the fastest and most convenient option. But to the delight of those who feel a thrill hearing the whistle coming down the tracks, more night trains will be pulling into the platform.
