Some of Europe's most exciting cities can be reached for less money on a sleeper train than a plane, according to new research.
Trundling across the Continent's rail network on a train while kicking back in the buffet car with a croque monsieur and a coffee can be more appealing than sitting in an economy cabin (and often, being separated from your party unless you've paid extra to sit together).
Unfortunately train tickets are often much more expensive than ultra-budget flying, with airfares to warmer climbs still regularly available for £10 or £15.
