3. Le Train Jaune, France
For more than a century, this metre-gauge yellow train has been winding its way through the French Pyrenees from Villefranche-de-Conflent to Latour-de-Carol. What it lacks in distance – it’s only 63km and about three hours long – it more than makes up in the dramatic mountains of the Parc Naturel Régional des Pyrénées Catalanes.
It also stops at France’s highest railway station, Bolquère-Eyne, which sits at 1592m above sea level, and crosses the Pont Gisclard, a railway suspension bridge.
4. Rhine Valley, Germany
Follow the curves of the River Rhine as it makes its way from Koblenz to Mainz – one of the shortest yet sweetest railway journeys in Germany. It’s only a fifty-minute ride, but along the route you’ll see fairy-tale castles and vineyards clinging to the river’s slopes.
If you want to make more of the ride, take the slow train that stops in laid-back riverside spa towns.
