The Royal Scotsman

Where: Around the Scottish Highlands or all the way around Great Britain.

Cost: $$$$$
Duration: Trips into the Highlands can be as short as two days or as long as five. Seven days will get you all the way around Great Britain in the most stylish mode possible.
Highlights: Possibly the most expensive train journey in the world, you’ll be treated like a member of the monarchy. Indulgent cuisine, fine wines and cabins that look like guest rooms at Balmoral await those willing to part with a minimum of $3600 (approximately) for a two-night trip.

The Chepe

Where: Mexico, starting in the mountains of Chihuahua and finishing on the Sinaloa coast.
When: In the rainy season, from June to October, you’ll get lush vegetation and blooming cacti, although mid-summer temperatures can reach 44°c.
Cost: $
Duration: Doing the route straight through takes fourteen hours, but you’ll want to stop off overnight and explore the very traditional towns along the way.
Highlights: The train winds its way down through 656km of the spectacularly beautiful Copper Canyon (which is deeper than the Grand Canyon), over 37 precarious-looking bridges and through 86 tunnels. The local indigenous peoples, the Tarahumara, sell their crafts and foods along the railway route.
