Eurostar Upgrades Future Train Fleet to Withstand Temperatures of Up to 55C
Eurostar is strengthening its long-term climate resilience by equipping its next generation of high-speed trains with air conditioning systems capable of operating in temperatures as high as 55C, following a series of intense European heatwaves that disrupted rail services this summer.
The decision reflects growing concerns over the impact of extreme weather on transport infrastructure as climate change brings more frequent and prolonged periods of high temperatures across the continent.
The upgraded trains, known as Celestia, are scheduled to enter service in 2031 and are expected to remain in operation into the 2060s. Eurostar said preparing the fleet for future climate conditions is essential given the expected lifespan of the trains.
“A decision has been taken to equip our new fleet of up to 50 Celestia trains with air conditioning capable of operating in temperatures up to 55 degrees,” a Eurostar spokesperson told the Daily Mail.
“These trains will enter service in 2031 and run into the 2060s so it’s essential to be prepared for the future,” the spokesperson added.
When the order was first announced late last year, the Celestia trains were designed to function in temperatures of up to 45C. Following this year’s severe heatwaves across several European countries, Eurostar opted to increase that threshold by 10 degrees.
France has been among the countries hardest hit by extreme temperatures. The southwestern town of Pissos recorded 44.3C in June, marking the highest temperature ever measured in the country for that month and highlighting the growing challenge facing transport operators.
The new fleet will be built by Alstom Group and will introduce several changes beyond enhanced climate protection. The double-decker trains will be the first of their kind to operate through the Channel Tunnel and on Britain’s domestic high-speed rail network.
Each train will measure approximately 200 metres in length and accommodate up to 540 passengers, representing a 20 percent increase in seating capacity compared with existing trains. They will serve Eurostar’s current international routes connecting five countries while also supporting planned expansion to Geneva and Frankfurt.
Eurostar has placed an initial order for 30 Celestia trains and retains the option to purchase 20 more as it works toward increasing annual passenger numbers to 30 million.
The company has experienced firsthand the operational impact of extreme heat. On June 25, four services between London St Pancras and Paris Gare du Nord were cancelled after high temperatures affected rail operations across parts of the network.
The investment comes as Eurostar’s contribution to the UK economy continues to grow. The operator is estimated to generate around £2 billion (€2.34 billion) annually for the British economy, with that figure expected to rise over the coming decade as demand for international rail travel increases and the network expands.

AlUla Manara to Bring World-Class Astrotourism Hub to Saudi Desert
A major new astrotourism destination is set to open near Saudi Arabia’s AlUla region, adding to growing global interest in space tourism and stargazing experiences. The upcoming AlUla Manara project will combine scientific research facilities with public viewing spaces in one of the region’s designated Dark Sky Parks.
Interest in space-based tourism has surged in recent years, driven by rare astronomical events, stronger-than-usual northern lights activity, and renewed global focus on lunar exploration programmes such as Artemis II. With upcoming celestial events including a solar eclipse expected over parts of Greenland, Iceland and Spain this August, and another widely anticipated “eclipse of the century” projected for 2027, demand for dedicated stargazing destinations continues to grow.
AlUla Manara will be located around 70 kilometres north of AlUla city, an area already known for its archaeological significance, including the UNESCO World Heritage site Hegra. The new development is positioned as both a visitor attraction and a scientific observatory, reinforcing the region’s expanding cultural and scientific profile.
The facility will feature advanced astronomical equipment, including a primary telescope with a four-metre diameter and two additional telescopes measuring two metres each. Once completed, it is expected to rank among the largest observatories in the world. The wider site plan also includes accommodation facilities and a dedicated stargazing lodge, allowing visitors to stay overnight in the desert environment.
The name “Manara,” derived from Arabic, translates to “lighthouse,” reflecting the project’s ambition to serve as a guiding point for scientific discovery and public engagement with space.
Designed by Heatherwick Studio, the architecture draws inspiration from spiralling cosmic formations such as galaxies and planetary rings. The design also reflects mathematical patterns found in nature on Earth, including those seen in plants, shells and fossils. The building will house exhibition spaces, a planetarium, dining facilities, and a rooftop observation deck intended for direct sky viewing.
Studio representatives said the project aims to reshape the traditional concept of observatories, which are often seen as remote and inaccessible. Instead, AlUla Manara is designed to create an immersive environment that brings scientific exploration closer to the public.
While AlUla International Airport currently has no direct flights from Europe, the region is accessible via domestic connections from Riyadh and Jeddah, as well as regional hubs including Doha and Dubai.
