Erstfeld

Updated: August 2026 – If you know the name Erstfeld, you probably know it because of the banking locomotives. For more than a century, this place in the Reuss valley was where heavy trains got the extra power for the climb up the Gotthard north ramp. Then a tunnel was built that doesn’t go over the mountain but under it – and Erstfeld became the portal area of the world’s longest railway tunnel.

This page describes honestly what still runs through here today, where to stand for it, and why you should pack some patience.

Why the mountain begins right here

The Reuss valley climbs gently from the north until it meets the Gotthard massif at Erstfeld. What follows is the classic ramp: tight curves, spiral tunnels, a steep gradient. For the railway, that meant for decades that trains had to be reformed and reinforced here – hence the depot, the crews and the banking locomotives.

Since the base tunnel opened, that logic has shifted. Most of the heavy traffic no longer needs reinforcement, because it no longer climbs the mountain at all. For you as a spotter, that’s the key piece of information: a large share of Gotthard traffic has become invisible at this spot.

What’s left is still worth seeing: traffic in the valley floor ahead of the portal, mountain-line traffic, regular-interval regional services – and a landscape you won’t find at any major Swiss station.

What still runs today, and when

Season	What you see	Light in the valley	Constraints
Spring (April–June)	Freight traffic, mountain-line trains, first excursion services	increasingly good	leftover snow on the hillside paths
Summer (July–August)	full range, plus excursion and special services	usable all day	little shade, hot in the valley floor
Autumn (September–October)	freight traffic at its yearly peak, clear air	very good, low sun	early sunset
Winter (November–March)	reduced traffic, but winter service vehicles	valley floor in shadow for long spells	cold, paths sometimes not cleared
Open days	heritage vehicles, special runs	depends on the date	many visitors, viewpoints in short supply

Autumn is the underrated season here: clear air, good low light, and freight traffic – including the container trains of Hupac – running at a high level ahead of the holidays. For background on the heritage vehicles that run on open days, see the heritage railway guide.

The day plan that works in Erstfeld

Photography in the valley floor: light, motorway, focal length

Erstfeld sits between two steep valley sides, and they set the tone for the day. In the summer half of the year the sun climbs high enough to light the tracks for many hours. In winter it reaches the valley floor only briefly – but in return you get snow, clear air and light that never happens in summer.

The second issue is the motorway. It runs parallel to the railway line and is present, either in shot or in sound, at almost every viewpoint. If that bothers you, you need to gain height or work with tighter framing.

The mountain line over the base tunnel: the real appeal

The shift of heavy traffic into the tunnel has, paradoxically, done the old line some good – at least from a spotter’s point of view. Today the mountain line carries traffic that’s clearly different from the standard long-distance services on the Swiss network: its own rolling stock, its own look, its own timetable logic, aimed at travellers who want to see the landscape.

That makes Erstfeld a place with two faces. In the valley floor you see the modern axis with its heavy freight traffic, much of it run by SBB Cargo International; further up the valley begins a line that has by now become almost a monument to itself. If you want to see both in one day, combine Erstfeld with the north ramp near Wassen.

Safety in Alpine terrain

Erstfeld demands more attention than a city station, and in two directions: towards the railway and towards the terrain.

Verdict

Erstfeld is a spot with a past, and that past is part of the appeal. You can tell there used to be a lot more going on here – and that’s exactly why you understand, here, what the base tunnel has meant for the Alpine axis.

As a sole destination for the day, Erstfeld is too thin. As the first stop on a Gotthard tour, as a place for calm landscape shots, and as a point where railway history and modern infrastructure sit side by side, it’s hard to replace.
