Battery-powered trains are looking to shape the future of Europe’s rail after the first successful trial of an intercity battery train in the northeast of England. This ‘tribid’ train easily switches between battery, diesel, and electric power.

Right now, the UK’s railways run diesel trains, which draw their power from overhead electrified wires or onboard diesel generators. However, the last generation of diesel trains is due to be replaced, and so a phase-out to cleaner alternatives is underway.

The trial happened in the region that first brought coal-powered engines to the world and as Britain celebrates 200 years of the modern railway next year.

High-speed and cheaper? Battery-electric trains show promise

Using just one powerful 700kw battery, this innovative technology can run trains at speeds over 75mph (120kph), making them high-speed.

During the trial, the train operated solely on battery power for 70km before switching back to its diesel engine, but the engineers say this range is enough to cover a typical intercity route that includes bridges, tunnels, and stations.

When launched, it’s expected that the train will have a range of between 100 and 150kms.

Single-battery trains not only boast superior performance, but they’re also more cost-effective than diesel trains.

They can reduce fuel costs by around 35 to 50 per cent, according to this trial which was run by Angel Trains, Hitachi Rail, and TransPennine Express.

Passengers will no doubt hope that any cost savings will be passed on to them, particularly given rising ticket costs, which go up every year in many parts of Europe.

Battery-powered trains are more environmentally considerate

Electric trains are currently considered the best solution to delivering clean trains as part of the global railway industry’s transition to net zero. Other options, such as trains that use grey hydrogen, are carbon-intensive, as Euronews Green has previously reported.

Using battery-powered trains reduces the need for rail operators to install or upgrade overhead wires on any unelectrified tracks. In turn, this could save Europe billions of euros in electrification projects.

It’s good news for those who live near train stations, too. Battery-run trains can enter and leave stations in zero-emission mode, drastically reducing noise and air pollution.

“The success of this trial will pave the way for even greener, more reliable journeys for millions of passengers,” said the UK’s rail minister, Lord Hendy.

When will everyone get to travel by battery-powered trains?

The evolution of battery-electric technology is moving quickly.

Hitachi Rail is already considering this next-generation technology for railway networks and other large vehicles globally. This latest success comes after delivering the world’s first passenger battery train in Japan and Europe’s first battery ‘tribrid’ train in Italy, the Masaccio, a couple of years ago.

A EuroMasaccio platform is already on track to be rolled out across European countries, and if Italy’s project is any indication, this could immediately cut CO2 emissions in half when replacing existing diesel train fleets.

Meanwhile, Siemens Mobility has also developed bi-mode battery trains that are already being used by passengers in the Ortenau region of Germany, saving 1.8 million litres of diesel every year. Plans are underway to roll them out across more countries, including the UK and more regions in Germany, within the next decade.

Siemens’ new trains only require small sections of track to be electrified, as the company supplies its own fast-charging points along the route, known as Rail Charging Converters (RCCs).
