Jane Jurgens finds four of the world's most beautiful rail trips with the best photo opportunities.
GLACIER EXPRESS - ZERMATT TO ST MORITZ, Switzerland
The Swiss do railways and scenery exceptionally well - and the two combined result in an experience you're unlikely to forget. The Glacier Express is considered one of the top scenic lines in the world, tracing a route between two of the country's most beautiful winter resorts, Zermatt and St Moritz. You'll see numerous picture-perfect Swiss towns backed by perfect fairytale mountains along the way-the photo opportunities are endless.
THE JACOBITE, Scotland
This steam-train journey travels through the Scottish highlands from Fort William to Mallaig, through some impressive extremes. The journey starts near Britain's highest mountain, Ben Nevis, and passes close by Loch Morar, the deepest freshwater loch, arriving next to the deepest seawater loch in Europe, Loch Nevis. Harry Potter fans will want to have their cameras out for the Glenfinnan Viaduct, famously featured in the films. Travelling on the Jacobite will leave you feeling like you've been on the Hogwart's Express.
