Night trains, and the day you get back

The argument for the sleeper train is not romance. It's arithmetic.

A daytime transfer between two cities eats a chunk of a day you could have spent somewhere. A night train eats a night you'd have spent asleep anyway. On a trip of four or five days, converting one travel day into a travel night is a measurable increase in the amount of holiday you actually get.

That's the whole case. Everything else is a bonus.

What you're actually trading

Sleep quality, mostly. A moving train is not a still bed. There's motion, there's noise, and there are stops. Some people sleep well on trains almost immediately; some never quite do.

The accommodation types matter more than anything else here:

• Seats are the cheapest and the worst for sleeping. Fine for a short overnight leg, hard work for a long one.
• Couchettes are shared compartments with simple bunks, usually four or six berths. Sociable, basic, and much better than a seat.
• Sleepers are proper beds in compartments with fewer berths, sometimes with a washbasin or private facilities. Meaningfully more comfortable and priced accordingly.

For a first attempt, a couchette on a shorter route is a reasonable way to find out how you cope without committing much.

Where the arithmetic works best

Night trains earn their keep on routes where:

• The distance is right. Long enough to fill a night, not so long that you arrive exhausted. Roughly a working night's sleep plus a bit.
• The endpoints are city centres. This is the underrated advantage over flying. No airport transfer at either end, no arriving at a terminal an hour outside the city you wanted.
• The alternative is a whole day. If the daytime option is a couple of hours, take the couple of hours.

The practical details that make or break it

Arrival is early. Sleepers often reach their destination in the early morning, before check-in anywhere. Plan the first few hours: left luggage, a long breakfast, an early-opening site. Arriving with no plan at seven in the morning carrying a bag is how a good idea becomes a bad morning.

Bring less. You'll be handling your own bag in narrow corridors and lifting it into a rack. This is not the trip for the big case.

Pack a small night kit separately. Earplugs, eye mask, water, a layer, toothbrush — reachable without opening the main bag in a dark compartment with strangers.

Book earlier than you think. Sleeper capacity per train is small compared to a plane, and the good berth types go first.

The part that is romance

Having made the practical case: there is genuinely something to it. Falling asleep in one country and pulling up the blind on another is a sensation flying does not produce, because flying removes the in-between entirely.

Waking early and watching unfamiliar landscape go past in the first light, with the compartment still quiet, is one of the better small experiences in travel. It is not a reason on its own to take the train. It is a very good reason to take the train once you've established that the schedule works.

Where this fits in a short trip

On a four-day trip, an outbound night train can effectively give you a third full day. That's a 50% increase in usable time for the cost of one imperfect night's sleep.

Whether that's a good trade depends on how well you sleep — but it's worth calculating properly before dismissing it, because the instinct is to think of overnight travel as a cost rather than as a day recovered.
