Key takeaways
- The Bergün–Preda section is the heart of the Albula line: over 400 metres of climb with three spiral tunnels packed into a short distance.
- The railway trail makes the line walkable – you hike alongside the line instead of viewing it from afar.
- Plan downhill, not uphill: take the train to Preda, then walk to Bergün.
- The timetable is the big advantage over the standard-gauge mountain lines – you rarely wait long.
- In winter the closed pass road becomes a sledging run, with its own viewpoints and its own rules of consideration.

The best viewpoints
Every viewpoint listed here is on publicly accessible ground. Tracks, shunting areas and operational railway land are off limits – even if the angle would be better from there.
Railway trail in the spiral-tunnel section
Between Preda and Bergün the path leads right through the zone where the line loses height in loops. You see the same train several times at different levels and can easily walk on between sightings. Information boards explain along the way what you're looking at.
View of the Albula viaducts above Bergün
The masonry viaducts over the Albula sit stacked so that you get several levels of the line in one shot. The classic view of the alignment that the line is famous for – without needing to climb anywhere for it.
Bergün with station and railway museum
The village itself is a starting point, fallback option and destination in its own right. At the station you sort out the timetable, and at the Albula Railway Museum you can bridge a rainy spell or round out the day with the line's technical history.
Preda and the upper ramp
At the upper end of the section the landscape opens up and grows starker. From here you start the descent, this is where the sledgers arrive in winter – and here you get trains against a backdrop that feels more like a high valley than an Alpine one.
Winter viewpoints along the sledging run
When the pass road is closed and groomed as a sledging run, a wide, cleared path runs close to the line. That gives winter viewpoints found nowhere else – though you need to watch out for sledge traffic.
What you will see here
Your haul at Albula line near Bergün
- Three spiral tunnels within a few kilometres – the same line in view several times
- Albula viaducts stacked one above another on the valley flank
- Railway trail with information boards right beside the line
- Reliable basic timetable – waiting times stay manageable
- Metre-gauge freight traffic, barely seen anywhere else these days
- Sledging in winter on the closed pass road
- Albula Railway Museum as a bad-weather alternative in the village
Is it worth the trip?
In favour
- Alignment and structures are fully visible from the footpath
- Predictable timetable – you know when the next train is coming
- Doable without a car: train up to Preda, walk down, train back from Bergün
- Usable year-round, with a completely different winter programme
- Suitable for families, because trail, museum and sledging complement each other
Against
- Little variety of rolling stock – the same trains all day
- The valley basin falls into shadow early, so the light window is short
- The trail and sledging run are busy in high season
- The winter path is a sledging run, not a photo spot – you must give way
- Getting to Graubünden takes time and isn't cheap
Updated: August 2026 – Most mountain lines are something you look at from a distance. The Albula line near Bergün is one you can walk. Between Preda and the village, the metre-gauge line loses over 400 metres of height, and because it does so with spiral tunnels and staggered viaducts, a trail runs right through the middle of the structure. You don’t walk to a viewpoint – you move through the logic of the line itself.
This page shows you how to divide up the section, what advantage the timetable gives over the big standard-gauge ramps, and what winter fundamentally changes.
Log the same train several times – without losing track
Between spiral tunnels it's easy to lose track of which level you've already covered. Note it down straight away, right on the path.
How 400 metres of climb fit into so short a distance
The Albula line is an adhesion railway – it runs without a rack system, on friction between wheel and rail alone. That limits how steep it can be. Yet between Bergün and Preda there’s a height difference of around 416 metres, over a straight-line distance you could walk in a good hour.
The builders’ solution was to lengthen the line artificially. They laid three spiral tunnels in which the line turns back inside the mountain, and carried it over masonry viaducts across the valley several times. As a result, the alignment sits stacked in several levels on the same valley flank.
For you, that means something almost no other spot offers: a single train stays within reach for a longer stretch of time. You photograph it at one level, walk a little further and, with the right choice of path, get it again. That takes a lot of the sting out of the seemingly thin timetable.
The timetable is the real luxury here
Anyone coming from the standard-gauge mountain lines notices the difference immediately. On the Gotthard north ramp or the Lötschberg south ramp you wait for individual trains and hope for diversionary traffic. On the Albula line of the Rhaetian Railway a basic timetable runs throughout, because it’s the main connection to the Engadine – with no base-tunnel alternative siphoning off its traffic.
That makes planning completely different: you hang your hike on the timetable instead of ignoring it and trusting to luck. And on the same day you get regular service from the Rhaetian Railway, panorama trains and, with a bit of patience, metre-gauge freight trains too – a combination barely found anywhere else in Europe. The guide on tracking Swiss trains live covers how to check the current situation in advance.
The most efficient way to do the trip
Take the train up to Preda and walk down. The descent takes two to three hours with stops, you have the structures ahead of you rather than behind you, and at any point you can decide whether to wait for one more train. Anyone who climbs the other way arrives at the top exhausted and gets the same shots against the light.
How many trains do you get on the trail?
A guide value for the Preda – Bergün section. Weather and choice of path shift the result considerably.
Every season is a different line
| Season | Access to the section | What makes the shot | What speaks against it |
|---|---|---|---|
| Spring | trail higher up sometimes wet or closed | leftover snow on the viaducts, clear air | uncertain path conditions |
| Summer | trail fully walkable | full alignment on view, long hours of light | most visitors |
| Autumn | trail walkable, quieter | colours in the valley, low sun | light window becomes short |
| Winter | pass road closed, groomed as sledging run | snow, snow-clearing vehicles, unusual viewpoints | must give way to sledging traffic |
| Off-season | limited, check conditions | empty paths, undisturbed work | operation and paths unreliable |
Winter is the biggest break with the rest of the year. When the road between Preda and Bergün is closed to cars and groomed as a sledging run, a wide, cleared path forms close to the line – but strictly as a sports venue. There you’re a guest, not a photographer with priority.

How to structure the day
Start in Bergün
Get your bearings in the village first: check the timetable, assess the weather, and plan the railway museum as a rain option if needed.
Take the train up to Preda
The ride up is part of the programme – you travel through exactly the spiral tunnels you're about to photograph from the outside.
Take in the open ground up top
Around Preda the landscape is open and stark. Catch one or two trains there before you descend into the forest.
Work through the levels one by one
On the descent, stop deliberately at the viaduct views instead of pausing briefly everywhere. Three good spots beat ten mediocre ones.
Review at the bottom
Back in Bergün, sort your sightings while you can still place them. The article analysing your spotting statistics shows why this pays off in the long run.
Are you logging your sightings properly?
- Every sighting noted with time and direction of travel
- Repeat sightings of the same train marked as such
- Vehicle number noted, not just the class
- Viewpoint or level recorded
- Photos linked directly to a sighting
- Special workings such as freight or works trains logged separately
- Entries finished on site, not left until the evening
The article keeping a sightings logbook describes how to build one that still holds up years later.
Safety on the trail
The railway trail is deliberately laid out so that every worthwhile view is possible from public ground. That’s exactly why there’s no reason to leave it.
Two things that regularly go wrong here
First: the trackbed, tunnel portals, viaducts and galleries are railway property and must not be entered. Inside the spiral tunnels, trains can't be heard until shortly before they emerge, and they come from a direction you don't expect. Second: in winter the cleared path is a sledging run. Sledges are fast, hard to brake and don't swerve out of the way. Never stand in the track to take a photo, and step to the side when photographing.
Bergün is right if …
- you want to photograph the alignment and its structures
- you need predictable times rather than waiting around
- you're travelling with family or want to combine the trail with the museum
Combine it if …
- you want the big single landmark shot – then the Landwasser Viaduct in the morning
- you're after more narrow-gauge lines – then continue over the Bernina line to Tirano
- you need a hub as a base – then travel in via Basel SBB
Go somewhere else if …
- you want to collect a variety of rolling stock – the trains here repeat
- you're after heavy standard-gauge freight trains
- you don't want to walk for two to three hours
Verdict
Bergün is the place where a mountain line stops being just a photograph and starts being a structure you can understand. The trail takes you through three spiral-tunnel levels, the viaducts sit visibly stacked one above another, and the timetable means you’re not waiting hours for one single train. Anyone wanting to work through the engineering behind it once more at their leisure will find the perfect complement in the village at the Albula Railway Museum.
The limit is on the vehicle side: anyone wanting to collect numbers sees the same trains all day. But anyone who understands and photographs lines will find one of the most instructive sections in the European rail network between Preda and Bergün – and a completely different line again in winter.
In short
A metre-gauge mountain line you can walk, with three spiral tunnels, a predictable timetable and a trail that explains the line's logic. Little variety of rolling stock, but line shots you'd otherwise only see from the train window.

Summer hike, winter day, panorama and freight trains: with a logbook you can see when each season is really worth it.
Summary
- Bergün is the mountain line you can touch: spiral tunnels, viaducts and the line's logic become visible on a single hike.
- Vehicle collectors won't get much out of it, but line photographers very much will.
- The predictable timetable makes the trip calculable – a rare luxury in the mountains.
- Visitors in winter get a completely different line, but must defer to the sledging operation.
Frequently asked questions
Why does the Albula line run in loops?
Because there's a height difference of around 416 metres between Bergün and Preda, while the straight-line distance between them is very short. As an adhesion railway without a rack system, the line can only be so steep, so it had to be made longer instead. The builders solved this with spiral tunnels, in which the line turns back inside the mountain, and with staggered viaducts crossing the valley several times. The result: you see the same train several times within a few minutes at different levels.
What is the Albula railway trail?
A marked footpath between Preda and Bergün that follows the line and uses information boards to explain how the alignment works. It's the real reason this section is so rewarding for railway fans: instead of holding one fixed spot, you move between the levels and pass practically every structure on the section along the way. Allow two to three hours for the descent with photo stops.
Which direction should I walk?
From top to bottom, so take the train up to Preda and walk back down to Bergün. The descent is considerably more pleasant, you have the structures ahead of you rather than behind you, and you can call it a day at any point without still having to climb. It's possible the other way round too, but it takes more effort and brings no photographic advantage.
Which trains run here?
The regular service of the Rhaetian Railway between Chur and the Engadine, plus panorama trains and freight trains on metre gauge. Variety of rolling stock is limited – over the day you essentially see the same trains. Anyone wanting to collect vehicle types is better served at a hub station; the article identifying classes explains how to systematically work out what you're seeing.
How often does a train come?
About hourly in the basic timetable, supplemented by panorama, freight and works trains. That's a real advantage compared with the standard-gauge mountain lines at the Gotthard: you can time your hike around the timetable instead of ignoring it and hoping for luck. In high season the service becomes even more frequent.
What happens here in winter?
The pass road between Preda and Bergün is closed to cars and groomed as a sledging run – around six kilometres downhill. The railway then handles transport back up. For you that means cleared, wide paths close to the line, snow on the viaducts, and a scene that doesn't exist in summer. But it also means you're moving through a sports venue and must not get in anyone's way.
Is the spot suitable for families?
Yes, unusually well. The trail is manageable downhill, the boards explain the line in an accessible way, the village has the railway museum, and in winter there's sledging on top. That makes Bergün one of the few railway spots where companions with no interest in trains can still have a good day. The article trainspotting for children and families has more ideas.
How do I combine Bergün with the Landwasser Viaduct?
Very easily, because both lie on the same line. A tried-and-tested split is: the Landwasser Viaduct near Filisur in the morning for the big landmark shot, the train up to Preda around midday, and the descent along the trail in the afternoon. That way you get the best-known single landmark and the logic behind the line in a single day.
Do I need special equipment?
In summer, sturdy footwear, water and weather protection are enough. In winter, add waterproof footwear, warm gloves and spare batteries – cold halves battery life faster than most people expect. Condensation when moving between the cold and a heated train is the second issue; how to deal with it is covered in the article on winter railway photography.
How do I get to Bergün?
By Rhaetian Railway via Chur, or from the Engadine through the Albula tunnel. Graubünden is well connected from Zürich main station, and you stay on metre gauge for the final stage. You don't need a car and won't want one – the sensible way to do the trip is up by train, down on foot.
