Route of high speed train from Geneva to Milan

There is some scenery in the upper Rhone Valley, then the Simplon Base Tunnel, completely under them in what was once the world's longest tunnel. Not really a high speed route, unless you are comparing it to the US.

Yes, the direct EuroCity trains that depart around 7:30 and 13:30 take a scenic route via Sion, Brig, and Domodossola and include less distance within a tunnel than those departures that have a connection in Zurich.

Thanks for your help

Here is a Swiss railway map:

Tunnels are indicated by dotted lines. You can see the Simpson Tunnel going between Brig and Domodossola.

Tony, yes. From Geneva to Milan you go:

• Around the north of Lake Geneva (views right)
• Up the Rhone valley to Brig (Humongous U-shaped valley)
• Through the Simplon Tunnel (dark - no views)
• Descend from the Alps (including spiral tunnels to loose height)
• Past Lake Maggiore (views left)
• Through the suburbs of Milan (read a book).

This is not a "High Speed Line", it is just normal speed.

@Sam, you are confusing the Simplon Tunnel with the Lötschberg Tunnel. the Lötschberg is the one that has been replaced by a longer base tunnel. Coming from Geneva you only go through the Simplon Tunnel.

Using the DB search function, I tested a random option for 26 April. It came up with these results for your trip. Your results may vary depending on your chosen date.

Click on "Show Details" for any of the options that have only 1 change. Continue to click on "Show Intermediate Stops" for other details about stops along the way. Finally click on "Map View." It will show your route.

In the same way, you can also take a look at options for trips with more than 1 train change to see if that would be more fun. They are different.

You can't buy tickets for this trip from DB, but you can certainly find out some important details. Personally, I love the maps.

Chris, maybe my terminology is unofficial, but the Simplon Tunnel really is a "base tunnel" as it dives into the side of the mountain exiting Brig station at the same level as the Rhone. It does pop out on the Italian side in a narrow valley with some descending yet to do. Not much to see on the Italian side as you are in the bottom of a very steep "V" slot valley until you get to Domodossola.

Sam, sorry, I was thinking you were saying there was another tunnel above it, as is the case with the Lötschberg.
The entrance is a "ground level" at Brig, just outside the station. But there is at least one spiral tunnel on the Italian side, to loose height.
