(CNN) — Excessive within the Swiss Alps, St Moritz made its identify as a spot for pushing the boundaries of winter sport. By the point it hosted the second Winter Olympics Video games in 1928 its status as a playground for rich adventurers was already effectively established.
On Saturday, the area continued its lengthy custom of increasing the bounds of what’s attainable with an epic world document try — not on snow or ice, however on rails.
To have a good time the a hundred and seventy fifth anniversary of Switzerland’s first railway, the nation’s rail business got here collectively to run the world’s longest-ever passenger prepare — 100 vehicles, 2,990 tonnes and nearly two kilometres lengthy.
Shaped of 25 new “Capricorn” electrical trains the record-breaking 1,906-meter prepare took nearly an hour to cowl round 25 kilometers (about 15 miles) over the spectacular UNESCO World Heritage Albula Line from Preda to Alvaneu in jap Switzerland.
Just like the legendary Cresta Run toboggan observe, the Albula Line is known for its limitless swooping curves and steep descents. A world-renowned masterpiece of civil engineering, the 62-kilometer line between Thusis and St Moritz took simply 5 years to construct regardless of requiring 55 bridges and 39 tunnels.
Previous to its completion in July 1904, guests confronted a dangerous 14-hour journey over tough tracks in horse-drawn carriages or sledges.
Centerpiece of the road is the 5,866-meter-long Albula Tunnel, which runs deep beneath the watershed between the Rhine and Danube rivers.
Spirals, hovering viaducts and tunnels
The prepare spiraled down a switchback of tracks via the mountains.
Following a part of the route taken by the world-famous Glacier Categorical since 1930, the world document try took within the spectacular Landwasser Viaduct and the extraordinary spirals that secured the road’s worldwide heritage standing.
In lower than 25 kilometers, the prepare plummeted from 1,788 meters above sea stage at Preda to 999.3 meters at Alvaneu, utilizing a succession of spirals, hovering viaducts and tunnels.
The document try was organized by the Rhaetische Bahn (Rhaetian Railway, or RhB), supported by Swiss train-builder Stadler, and is maybe much more astonishing for going down on a slender gauge railway.
In contrast to most Swiss and European railways, which use the “commonplace” gauge between the rails of 1.435 meters (4 ft 8.5 inches), RhB rails are only one meter aside.
Mix this with a route with notoriously tight curves, steep gradients, 22 tunnels and 48 bridges over deep valleys and the challenges turn into apparent.
Earlier holders of the world’s longest passenger prepare document — Belgium and, earlier than that, the Netherlands — used commonplace gauge railways via flat landscapes to their benefit.
Nevertheless, preparations began months forward of the RhB occasion, together with take a look at runs to make sure the distinctive prepare might be operated safely.
“Everyone knows the Albula Line very effectively, each change of gradient, each incline,” stated lead driver Andreas Kramer, 46, forward of the massive day. “It goes with out saying that we’re going via the method repeatedly.”
He added: “We have to be 100% synchronized, each second. Everybody has to maintain their pace and different methods below management always.”
An preliminary take a look at run led to failure earlier than the prepare had even moved when it was found that the emergency brake system couldn’t be activated and the seven drivers couldn’t talk with one another by way of radio or cellphone within the many tunnels.
Kramer, assisted by six different drivers and 21 technicians as an alternative used a brief discipline phone system arrange by the Swiss Civil Safety group to keep up communications because the prepare ran at as much as 35 km/h via numerous tunnels and deep valleys.
Specifically modified software program and an intercom between the seven drivers allowed the 25 trains to work in concord. Any mismatch in acceleration or deceleration in the course of the journey would have exerted unacceptably excessive forces on tracks and energy provides, creating a serious security concern.
RhB Director Renato Fasciati stated: “Switzerland is a railway nation like no different. This 12 months, we’re celebrating 175 years of Swiss railways. With this world document try, RhB and its companions needed to play their half in attaining a pioneering feat that had by no means been seen earlier than.”
The prepare was made up of 100 vehicles.

On the lengthy descent, pace was managed by regenerative braking, just like that used on some electrical vehicles, which fed present again into the 11,000-volt overhead energy provide strains.
Nevertheless, with so many trains in the identical part of line, there was concern that they might feed an excessive amount of present again into the system, overloading each trains and native energy grids. To keep away from this, the highest pace of the prepare was restricted to 35 km/h and software program needed to be modified to limit the ability being fed again.
Extra security management cables additionally needed to be fitted all through the prepare to help the usual mechanical and pneumatic connections between trains.
On the massive day, the RhB organized a railway competition at Bergün and three,000 fortunate ticket holders had been in a position to witness the document try by way of a dwell TV feed whereas additionally having fun with native leisure and gastronomy. Regular companies via the Albula Tunnel to St Moritz and past had been suspended for 12 hours.
Three satellite tv for pc uplinks, 19 cameras in drones and helicopters, on the prepare and alongside the observe filmed the prepare, offering a singular document of this once-in-a-lifetime occasion. This alone was a serious problem in a distant, mountainous area with restricted cell telecoms protection.
A railway nation

For a small nation with a mountainous panorama which, at first look, appears unsuited to railways, Switzerland punches effectively above its weight within the business.
Necessity has lengthy made it a pioneer in electrical, mechanical and civil engineering and its expertise and experience are exported all around the world.
With good motive, the Swiss are the world’s most enthusiastic rail customers, touring a median of two,450 kilometers yearly by prepare — 1 / 4 of their total annual whole. In widespread with different European international locations, mobility has exploded in current many years — the common annual distance travelled by automobile and public transport has doubled within the final 50 years.
They traveled 19.7 billion passenger kilometers by rail in 2019, the final “regular” 12 months earlier than the Covid-19 pandemic. In 2021 this fell to 12.5 billion passenger kilometers however as Switzerland celebrates 175 years since its first railway opened between Zürich and Baden, ridership is effectively on the way in which again to pre-pandemic ranges.
So excessive are the expectations of public transport customers in Switzerland that even a small delay is a supply of quiet dissatisfaction. And never with out good motive; many journeys in and round Switzerland’s greatest cities are multi-modal, reliant on slick connections between trains, trams, buses and even boats at well-organized interchanges.
In 2021, Swiss Federal Railways (SBB) operated 11,260 trains carrying 880,000 passengers and 185,000 tonnes of freight per day on a 3,265 kilometer-long community with 804 stations.
Including the 70-plus “personal” commonplace and slender gauge railways, lots of that are additionally partly or absolutely in public possession, takes that community to round 5,300 kilometers, the densest rail community on the planet.
Many years of long-term funding have created a core community of intensively used fundamental strains linking all of the nation’s main cities. Feeding into this are high-frequency S-Bahn (metropolis rail) methods across the greatest cities plus regional and native railway strains, tramways and mountain railways, lots of which give a vital hyperlink to the skin world for rural and upland communities.
Regardless of large funding over the past 4 many years, via long-term growth applications comparable to “Bahn 2000.” Switzerland’s railways have gotten a sufferer of their very own success. Whereas SBB’s total punctuality nonetheless appears to be like spectacular to outsiders, there may be concern about deteriorating efficiency, rising prices and its capacity to fund important upkeep and main tasks after the devastating monetary losses of 2020-21.
Disruption continues to be comparatively uncommon on the SBB community, however reliability has decreased in recent times because of congestion, employees shortages and poor punctuality of trains arriving from neighboring international locations.
The prepare dropped almost 800 meters in its descent from the mountains.
Sitting on the coronary heart of western Europe, between the commercial powerhouses of Germany, France and northern Italy, Switzerland additionally performs a key strategic function within the wider European financial system — because it has because the Center Ages.
For hundreds of years, the Alps introduced a formidable barrier to vacationers and commerce throughout this a part of Europe however over the past 20 years, billions of Swiss Francs have been invested to construct the prolonged Gotthard and Loetschberg Base Tunnels deep below the Alps.
Whereas different international locations argue and dither over public transport spending, in June 2022 the Swiss Federal Council opened consultations on its subsequent program of long-term rail funding. Perspektive Bahn 2050 is an in depth set of proposals with a transparent deal with creating quick and medium-distance passenger companies to advertise a shift away from vehicles.
Enhancement of the prevailing community to create further capability is to be prioritized over extra main infrastructure tasks. Transport Minister Simonetta Sommaruga says: “It isn’t a query of saving a couple of minutes on a trunk route comparable to Zürich-Bern. Rail is already unbeatable on routes like that. It’s slightly about growth the place rail has been left behind.”
Anticipated to be handed into legislation by 2026, the plan’s targets embody growing annual public transport utilization from 26 billion passenger-kilometers to 38 billionn passenger-kilometers by 2050, growing rail’s share of the passenger and freight markets “considerably” and making certain that rail companies are much more intently built-in with different transport modes to supply larger mobility for all.
Critics usually cite Switzerland’s smaller inhabitants and comparatively quick distances when evaluating it to international locations such because the UK and Germany, claiming that it will be unimaginable to create related built-in public transport networks in bigger international locations.
It is true that the Swiss have constructed one thing ideally suited to their geography, tradition and inhabitants density, however regardless of the arguments elsewhere, the RhB’s unbelievable achievement on October 29 is a vastly spectacular demonstration of Switzerland’s world-class capabilities within the discipline of railway expertise.
