Double decker trains coming to Eurostar as order placed​

Eurostar new trains Note: Final design and livery not confirmed


Alstom and Eurostar have announced a €2 billion deal that will see up to 50 new double-decker trains built for use on the Channel Tunnel.

The initial order of 30 new trains comes with an option for a further 20.

The fleet will be named Eurostar Celestia and will be based on the Avelia Horizon platform.

The trains will have around 540 trains but if they operated in 400m formation (as they do currently), each service would have around 1,080 seats.

The trains will be interoperable across all five countries served today as well as Geneva and Frankfurt.

These new trains are expected to be in service by May 2031.

The new trains will operate alongside Eurostar’s fleet of 17 e320s.

Eurostar says it will maintain the entire fleet at Temple Mills depot in London, which will create 350 jobs at the depot.

The operator also says that they are the most sustainable fleet of trains that they have operated, with 97% recyclable components (25% made from recycled materials) and 20-50% energy savings compared to the current fleet.


“Placing this milestone order marks the concrete realisation of Eurostar’s ambitious growth strategy – to reach 30 million passengers by investing in a brand-new fleet. We’re particularly proud to bring double-decker trains to the UK for the very first time.

“Customers can expect a very special new train with Eurostar Celestia, which will offer exceptional comfort, a unique Eurostar experience and new surprises to be revealed. This is a golden age for international sustainable travel – and Eurostar is leading the race.”

Gwendoline Cazenave, CEO, Eurostar
“By choosing Avelia Horizon to renew its fleet, Eurostar is confirming its desire to combine technological performance, energy efficiency and passenger comfort. This new-generation train, designed to meet the demands of international very high-speed traffic, embodies our vision of sustainable and competitive European mobility,”

Henri Poupart-Lafarge, Chief Executive Officer of Alstom

‘Whistling Dragon’ to run on Welsh railway during half-term break​

Whistling Dragon


The award-winning Ffestiniog and Welsh Highland Railways have announced that their popular ‘The Whistling Dragon’ steam service will return during this half-term holiday, in what it describes as a “mythical steam train adventure – where legends come to life.”

‘The Whistling Dragon’ will depart from Caernarfon Station, which will be decked out in spooky Halloween decorations, on Monday 27, Tuesday 28, Thursday 30 and Friday 31 October.

Caernarfon station was rebuilt in 2019 at a cost of £3.5 million.

The new Caernarfon station provides much-improved passenger facilities.

The building is designed to fit in with the spectacular surroundings, and is promoted by the railway as “a fitting gateway into the heart of the Snowdonia National Park”.

The Railway, which celebrated its platinum jubilee earlier this year, has created the steam train ride as a magical, dragon-themed adventure, which is inspired by the legendary Welsh Red Dragon.

Whistling Dragon passengers


After leaving Caernarfon station, which is adjacent to the historic Caernarfon Castle, the train will travel through the breathtaking landscapes and dramatic mountain views of Snowdonia.

Before the journey begins, young passengers will be given a special activity pack and will have the chance to take photos with the locomotive.

On board the train, passengers will be able to relax in dragon-themed carriages.

There will be fun activities which families can complete while the train winds its way to Rhyd Ddu, which is the railway’s highest station.

Hot, cold and alcoholic drinks and snacks will be available from the Buffet Carriage, and there is a toilet available on board for passenger use.

Whistling Dragon


The train will stop at Rhyd Ddu for half an hour, giving passengers the opportunity to explore, stretch their legs, and search for hidden dragons!

The train will return to Caernarfon after a trip lasting around three hours.

When the train gets back to Caernarfon, children will be able to exchange their completed sheets for a dragon sticker.

The railway also hopes that passengers will browse its gift shop’s themed souvenirs.


More information and tickets are available from the event’s web page.

From steam to sustainability: how Taff’s Well continues to connect Wales’ transport past and future​

Region & Route: Wales & Western: Wales & Borders


Walnut Tree 1960s


Fifty years after the Walnut Tree Viaduct was dismantled, its legacy lives on in the Taff Trail just outside Cardiff - where history, sustainability and community now travel side by side.

Welcome to the latest in our series of heritage articles looking at buildings and structures across the Wales and Borders railway in celebration of 200 years of the modern railway.

Heritage can mean more than preservation and restoration.

At times, it’s more about remembering what came before, and making use of some of the remnants of the past today.

A fine example of this exists close to Wales’ only natural hot spring.

The village of Taff’s Well sits just north of Cardiff, nestled in the narrow Taff Valley between the steep slopes of the Garth Mountain and Craig yr Allt.

As well as being home to the spring, whose warm mineral waters have attracted visitors for centuries for their supposed therapeutic properties, the village also hosts a striking, slender brick monolith of a chimney.

It stands proud, and somewhat out of place, beside the busy A470 dual carriageway.

The faint lettering still visible on its side might mislead passers-by into thinking it is a modern folly, perhaps erected in 1977 to commemorate the Silver Jubilee of Queen Elizabeth II.

In truth, it is neither chimney nor folly, and its story stretches back far beyond the 20th century’s royal celebrations.

What remains today of the Walnut Tree Viaduct, next to the A470

Taff's Well remains of old Viaduct

Taff's Well Walnut Tree Viaduct in 1960s


Turn of the century

For over 80 years, the imposing Walnut Tree Viaduct dominated the skyline over Taff’s Well, carrying heavy freight and passenger trains across the river.

Built by the Barry Railway Company in the 1890s, it was originally designed to carry coal and iron from the busy South Wales Valleys to the newly established Barry Docks - a port created to ease pressure on Cardiff’s overcrowded Bute Docks.

Its rural name contracts sharply with the industrial might the viaduct represented, and comes from a nearby farm and inn, which were well known coaching stops long before the railways arrived.

Completed in 1901, the viaduct was an imposing sight.

The design featured steel lattice girders resting on tall masonry piers, the longest span stretching 300 feet.

At over 1,200 feet in total length and rising 120 feet above the river, it was visible for miles around, the rhythmic clatter of steam locomotives part of daily life for the villagers living in its shadow.

It took three years and around seven million bricks to complete, and alongside the impressive seven girders, it earned the reputation as one of the finest railway spans in Britain.

Walnut Tree viaduct retained its strategic importance to the national rail system for decades.

The line it carried remained a vital artery until the 1960s, but then the shifting tides of industry and the Beeching-era cuts reshaped the rail map of South Wales.

The need for the viaduct dwindled, and between 1969 to 1974, piece by piece, entirely by hand (owing to the congested valley bottom below), it was dismantled.

Today, only two of its towering stone piers remain – monuments to the viaduct’s former glories.

One is mainly hidden by trees, while the other remains prominent and is adorned with well-wishes for the previous monarch.

Back to today

You may think the loss of the line and the remnants of the viaduct are the end of this story.

However, the line’s former path through the landscape continues to be used, not by rail enthusiasts, but by walkers, joggers, cyclists, and more.

This is because much of the former railway alignment is now part of the stunning Taff Trail, a 55-mile traffic-free corridor from Cardiff Bay to Brecon that follows the track laid down at the height of the steam era.

In this way, the Walnut Tree Viaduct’s role as a transport link continues, albeit in a greener, quieter form.

Its transformation mirrors a broader shift across the UK, where disused railways are being reimagined as sustainable travel and tourism routes, preserving history while serving present-day needs.

And what about tomorrow?

Taff’s Well remains an important point on Wales’ active rail network.

The main Cardiff-to-Merthyr line still runs through the village, and Taff’s Well station is a busy commuter stop.

Network Rail and Transport for Wales are investing heavily as part of the South Wales Metro project, with a new depot, modernised station facilities, and improved services planned.

While the Walnut Tree Viaduct is gone, its legacy endures in the towering stone piers that frame the valley, and in the trail that follows its course.

Steel, stone and sustainability bind the past, present, and future of this village together, and long may that continue.
