A dazzling POV video shows the route Europe's highest and one of its most spectacular railways takes through the mountains.
The clip was filmed via a camera attached to the front of a Jungfrau Railway train which wends its way through the Swiss Alps.
The iconic journey takes brave travellers from the Kleine Scheidegg train station to Jungfraujoch, which is Europe's highest train station at 3,454m (11,332ft) above sea level.
A long stretch of the 5.8 mile line tunnels through the North Face of the Eiger mountain, while Jungfraujoch station is buried beneath the peaks of Jungfrau and Monch.
The clip begins with the train stationary at Kleine Sheidegg station, which is a mere 2,061m above sea level.
The train takes off and begins to weave its way through the thick snow of the mountain in what can only be described as obscenely picturesque footage.
It takes a quick stop in the Eigergletscher station where trains are worked upon by engineers, before it ploughs into the Jungfrau tunnel.
It is in this dark cavern that the train passes the abandoned Eigerwand station, empty since it was closed to the public in 2016.
From here the train moved to Eismeer station, where passengers get off to take in views of the glacier Ischmeer from observation windows carved into the side of the mountain.
The train's final stop is Jungfraujoch, where most passengers hop off into a rapid lift that connects directly to the Sphinx observatory summit above.
With both an indoor and outdoor platform, the view of the peaks beyond from this alpine vantage point is stunning.
In true Swiss style, passengers are able to walk along a foot tunnel to the 'Top of Europe' building complex, which overlooks the Aletsch Glacier and has a Lindt chocolate gift shop.
Visitors can also head to 'Restaurant Crystal' for some 'authentic Swiss' cuisine, best enjoyed on top of a mountain.
Before heading back to the station and down the slope, passengers can check out the complex's 'Ice Palace' walkways, which feature ice sculptures of creatures such as eagles, penguins and bears.
The remarkable carvings were dug out of the hill by mountain climbers using pickaxes and saws in the 1930s.
The journey takes around 30 minutes, with the route running 365 days a year and attracting thousands of visitors annually.
The train company's website reads: "Standing on the Jungfraujoch 3,454 metres above sea level, you can feel it with your first step: this is a different world. It's one you have to experience."
One of the slight drawbacks of the experience is the price.
Those brave enough to take on the mountain and its staggering heights need to shell out around £92 for a ticket.
