The Caledonian Sleeper: This service connects the bustling city center of London with the Scottish hubs of Edinburgh, Glasgow and beyond. Waking up surrounded by Highland hills is an unforgettable experience.

Luxurious experience: In the mid-20th century, Scottish sleeper trains were designed to be as luxurious as possible. This image depicts the Nightcap Bar on the London to Glasgow overnight sleeper train in 1964.

New train experience: Come spring, the Caledonian Sleeper intends to hark back to its opulent origins with a revamp of the carriages and services on offer. This image depicts the club car on the new Scottish sleeper train service.

True romance? Train expert Mark Smith, AKA The Man in Seat 61, admits that the romance of sleeper train travel is overhyped, but sleeper trains remain one of his favorite forms of transport: "Romance is not something you buy, it's something that happens, it's in the eyes of the beholder, as it were," he says.

Incredible scenery: The journey takes you through mountains and across high railway bridges, through tunnels and past Alpine lakes.

Throwback: The sleeper cabins are pretty old, but that adds to the retro vibe.

Taking your chances: It's hard to book this train, there's no online service -- so you've got to turn up and chance it.

Belgrade to Bar: Perhaps the best idea to get the most out of the scenery is to sleep one way and then enjoy the daytime views on the way back.
