SBB Infrastruktur

SBB Infrastruktur isn't a separate company, but a division of SBB with separate accounts. It maintains most of the Swiss standard-gauge network – but not all of it: BLS, RhB, MGB and SOB have their own tracks, their own rules and their own rolling stock.

Key takeaways

  • SBB Infrastruktur is a division, not a separate company. The split between track and traffic in Switzerland runs within a single company with separate accounts.
  • The SBB network isn't the Swiss network. BLS, RhB, MGB and SOB run their own lines with their own rules.
  • The clock-face is the actual planning unit. Expansion follows the timetable – that's why train sequences are so predictable.
  • At the Gotthard, the main traffic now runs through the mountain, not over it. Anyone wanting to photograph the ramps needs to know what still runs there at all.
  • Who owns the platform decides access – not the logo on the train that happens to be standing there.

History at a glance

1902The Swiss Federal Railways are created by nationalising several private railways. Numerous companies remain independent – the basis for the still mixed network landscape today.
1982The nationwide clock-face timetable starts. From then on, infrastructure is planned to fit the timetable, not the other way round.
1999The SBB becomes a public limited company owned by the federal government. Infrastructure becomes its own division with separate accounting.
2007The Lötschberg Base Tunnel enters service – but it belongs to the BLS network, not to SBB. A good example that major Swiss projects aren't automatically SBB projects.
2016The Gotthard Base Tunnel opens and shifts the main traffic from the mountain route into the mountain.
2020With the Ceneri Base Tunnel, the north-south axis is completed; the old mountain route retains mainly regional and tourist significance.

How to recognise SBB Infrastruktur

Does the train really belong to SBB Infrastruktur?

Tick off everything that applies to the vehicle in front of you.

  • Platform signage in SBB design shows you the network operator, not the train operator
  • Standard gauge at 15 kV sets the SBB network apart from the metre-gauge networks at around 11 kV
  • Yellow maintenance vehicles and road-rail equipment work on the track, not in traffic
  • Signal aspects to Swiss regulations visibly differ from German and Italian installations
  • Station clocks and wayfinding follow SBB design even where other railways' trains call
  • Section boundaries and system changeovers mark the transition to other operators' networks
  • Network transitions to metre-gauge railways are recognisable by parallel tracks of different gauges

Strengths and weaknesses

What the company stands for

  • Very high train density – something is happening even at smaller stations
  • The clock-face timetable makes trips as plannable as in hardly any other country
  • Platforms are mostly well accessible and offer legal vantage points
  • The north-south axis brings Italian, German and Swiss vehicles together
  • Mountain routes remain usable as diversion and tourist routes

Where it falls short

  • The base tunnel has drawn the main traffic away from the photogenic ramps
  • Not every Swiss track belongs to SBB – rules and contacts change from network to network
  • The division isn't a separate company, which makes responsibilities confusing for outsiders
  • House rules apply on platforms; tripods and long stays can prompt questions
  • In dense clock-face service, a clear view of a track is often only available for seconds

Updated: August 2026 – Switzerland solves the separation of track and traffic differently from its neighbours: SBB Infrastruktur isn’t its own public limited company, but a division with its own accounts within SBB. For you at trackside, that changes little – for understanding who’s responsible for what, it changes a lot. And more importantly: by no means does every Swiss track belong to this division.

Separate books instead of separate companies

European law requires that a network operator not favour its own transport companies. Switzerland meets this through its organisation: infrastructure forms a ring-fenced area with its own accounting, and path allocation is handed to an independent body. There’s no separate company for this, unlike DB InfraGO in Germany or Infrabel in Belgium.

The practical effect is the same. SBB Cargo also pays for every path, and a private provider can apply for the same timetable slot. This becomes visible in freight traffic, where companies such as Crossrail and BLS Cargo operate on the same tracks.

Four networks, four rulebooks

Anyone travelling across Switzerland switches network operators more often than expected. The differences aren’t fine details: they decide gauge, electrification system and which vehicles you can even see.

Network Gauge Electrification system What you see there
SBB 1435 mm 15 kV / 16.7 Hz Long-distance, regional and freight traffic at dense frequency
BLS network 1435 mm 15 kV / 16.7 Hz Lötschberg traffic, freight trains towards Italy
Rhaetian Railway 1000 mm around 11 kV Albula and Bernina traffic, piggyback wagon operation
Matterhorn Gotthard Bahn 1000 mm around 11 kV Rack sections, Alpine regional traffic
Südostbahn 1435 mm 15 kV / 16.7 Hz Its own long-distance lines across the pre-Alps

This variety explains why completely different vehicles run at the Landwasser Viaduct near Filisur than at Zurich Hauptbahnhof – even though both are Swiss railways.

The clock is your timetable

In Switzerland, infrastructure is built to fit the timetable, not the other way round. Once you've seen a connection, it comes back at the same interval. Note the minute at your first observation – that gives you a grid for the whole day.

From the platform to a solid note

Determine the network

Standard gauge or metre gauge? That decides which operator is responsible and which vehicles run there at all.

Remember the clock-face minute

The first observation gives you the grid for all further trains at this spot.

Read the data panel

Country code and vehicle keeper marking turn a picture into a verifiable sighting.

Separate the type of traffic

Passenger train, freight train or maintenance train belong in different lists – otherwise engineering trains skew your statistics.

Note the location too

On ramp sections, even a single kilometre can decide whether a shot can later be attributed.

Estimate train density at the clock-face timetable

Add up which types of traffic run hourly or more often at your spot.

An estimate, not a timetable – but it shows whether a spot is worth hours or only minutes.

What the base tunnel did to your spot

The Gotthard is the best example of how an infrastructure decision can change an entire spotting area. Since the main traffic started running through the mountain, things have become noticeably quieter at the north ramp at Wassen. In Erstfeld, on the other hand, you can still see how trains are made up for the axis.

Anyone looking for heavy freight trains is now better served in Bellinzona or in Basel SBB. And anyone wanting to photograph the mountain route should check beforehand what still runs there at all.

Make network changes visible in your logbook

Record which network you're standing on – then metre gauge and standard gauge stay cleanly separated later.

Are you still standing in the right place?

Unproblematic if …

  • you stay behind the safety line on the platform
  • you photograph from a public path or a bridge
  • you're not obstructing staff or passengers

Take care if …

  • you want to set up a tripod on a heavily used platform
  • the spot on a ramp section is unpaved
  • a construction site has temporarily fenced off areas

Don't proceed if …

  • track or ballast would have to be entered
  • a depot or works area begins
  • railway staff ask you to leave the area

This line isn’t negotiable, and there’s a reason: in dense clock-face service, the next train arrives faster than any reaction would be possible. The distance rules are set out under safe distance from the track, and the legal side under trespassing on the track.

Tunnel portals aren't viewpoints

Around base tunnels and their approaches lie operational and emergency facilities that look unspectacular from a distance. They're closed off, usually monitored, and operationally essential in the event of an incident. Photograph from designated paths – the shots are usually better there anyway.

Verdict

SBB Infrastruktur is the reason Swiss rail operations feel so reliable: the track is built and maintained to fit the clock-face timetable. For you that means predictable train sequences and clearly regulated spots – but no information whatsoever about who’s running the train you’re looking at.

And the second lesson is just as important: Switzerland doesn’t equal SBB. Anyone who keeps that in mind gets vehicles, gauges and responsibilities right from the start.

In short

A division with its own accounts, not a separate company – and just one of several network operators in the country. For the sighting, the data panel remains decisive; for the location, the network operator.

Let the clock work for you

Log one sighting per train instead of one note per hour – Traintrack keeps number, place and time together.

Summary

  • The infrastructure division maintains the track and provides paths to all licensed railways, including its sister divisions.
  • Anyone spotting in Switzerland often switches unnoticed between different operators' networks – most noticeably at the transition from standard to metre gauge.
  • The Gotthard shows, as an example, how infrastructure decisions can shift entire spotting areas.
  • For identifying a vehicle, the data panel remains the key source; the network only tells you where you're standing.

Frequently asked questions

Is SBB Infrastruktur a separate company?

No. Unlike in Germany or Belgium, infrastructure in Switzerland is a division within SBB. It's the accounts that are separated, not the legal entities. The European requirement is thus met organisationally, not through a separate company like DB InfraGO.

Do all Swiss railway lines belong to SBB?

No, and that's the most common misconception. BLS, the Rhaetian Railway, the Matterhorn Gotthard Bahn and the Südostbahn operate their own networks. On the Albula line, for example, you're not standing on SBB land, but on that of a metre-gauge railway with its own operating regulations.

Who runs trains on the SBB network?

SBB's own traffic divisions, plus numerous other railways. In freight, operators such as BLS Cargo, Crossrail and Hupac run trains, and in regional traffic companies such as Thurbo. Network access is open to all licensed companies.

Why is there less activity at the Gotthard than before?

Because the base tunnel has absorbed the main traffic. Since then, the mountain route has carried mainly regional and excursion traffic, plus diversions during closures. Anyone looking for the classic shots at the north ramp at Wassen or the south ramp at Giornico should check the timetable carefully beforehand.

What does the clock-face timetable mean for my trip?

It makes train sequences predictable. Once you've observed a connection, it will as a rule come back at the same interval. That makes planning much easier – live data on this is provided in the article Tracking SBB trains live.

Am I allowed to photograph on Swiss platforms?

Photography from the platform is generally possible, as long as you don't obstruct or endanger anyone. However, the railway's house rules apply, and staff can give instructions. What follows from that is explained in the article on house rules at stations.

Why do metre-gauge railways have a different electrification system?

Because they were historically built independently. The standard-gauge network runs on 15 kV at 16.7 Hz, while several metre-gauge networks run on around 11 kV. That's why a vehicle from the Albula line can't simply switch onto SBB tracks, even though both networks are in Switzerland.

Where do I see the most international traffic?

On the north-south axis and in Basel SBB. There, the German and Swiss systems meet, and in freight traffic the trains from the Rhine valley heading towards Gotthard converge. In Bellinzona you see the southern end of the same axis.

Are engineering and inspection vehicles part of the infrastructure?

They work for it, but don't necessarily belong to it. Maintenance trains are often supplied by specialist companies and crewed by their staff. The yellow warning livery indicates function, not ownership – and clearly separates these vehicles from passenger and freight traffic.

Does the network operator help me identify a locomotive?

No. It only tells you where you're standing. Identifying a vehicle runs via the country code, vehicle keeper marking and number on the data panel. How to do that systematically is described in the guide Who's actually running this?
