Agatha Christie once said: ‘Trains are wonderful.’ Certainly, they were helpful to her, providing the inspiration for Murder On The Orient Express.

She knew all about the mystique of travelling on an overnight train, which is the setting for the BBC’s Nightsleeper drama, specifically on a chaotic, madcap Glasgow to London trip. 

But you don’t have to experience similar mishaps. Just bed down in one place and wake up in another. 

Here’s how to enjoy some of Europe’s top routes.

European Sleeper is a Belgian-Dutch co-operative launched last year, now operating thrice-weekly trains between Brussels and Prague, calling at Antwerp, Rotterdam, Amsterdam, Berlin and Dresden.

There are also sinks, but toilets are along the hall. 

Carriages are sleek, made of fluted stainless steel; originally from the US in the 1950s. Compartments with three-tier bunks can be booked privately for 1-3 people, or there are cheaper couchettes fitting 5-6. Catch a London-Brussels Eurostar for the onwards journey. Or join at Rotterdam, having taken a ferry to the Hook of Holland.
