A Swiss railway company broke the record for the world’s longest passenger train on Saturday as part of celebrations for the 175th anniversary of railways in the country.

The train consisted of 4,550 seats spread across 100 coaches.

The one-off world record journey was organised by Rhaetian Railway and took around an hour. Rail enthusiasts lined the valley to watch the train wind its way about 25km through the Alps.

Where did the longest passenger train journey take place?

The 1,910m long passenger train travelled along the UNESCO World Heritage Albula/Bernina route from Preda to Alvaneu and over the Landwasser Viaduct.

It’s regarded as one of the most spectacular train routes in the world thanks to amazing Alpine views. It glides through many quaint mountain towns and takes in dozens of viaducts and bridges.

The world record attempt was organised to celebrate the 175th anniversary of Swiss rails but also to show off to the world the beauty of Swiss train journeys according to Dr Renato Fasciati, CEO of Rhaetian Railway.

“We had some troubles during the corona crisis (COVID 19 pandemic), so we lost 30 per cent of our turnover for guests on the train and so we tried to find a good event in order to increase the awareness of our beautiful UNESCO’s World Heritage route. And so this world record attempt is a wonderful reason and a wonderful instrument for us to show the world this beautiful railway.”

How was this possible?

The build up to the journey threw up numerous technical challenges.

Fasciati says controlling the carriages is key with such a long vehicle: “When you put 25 trains together, the signal must be enough so that the last train really gets the information from the first train and the train is not built for this operation and so we had to find a very pragmatic solution which is safe, but which helps us really to do this wonderful train.”

And at almost 2km long, communication on the train was crucial, but difficult. A field telephone almost 2km long was set up, and 7 train drivers and 21 technicians worked on the train to ensure things ran smoothly.

The train will now be dismantled into its separate parts and they will be used for regular traffic.
