Short notes from overnight rail journeys across Europe.
A six-berth couchette is fine for one night if you take the top bunk: more air, fewer people climbing past you. For two nights in a row the sleeper is worth the money. Bring earplugs either way.
The included breakfast is usually a roll, butter, jam and coffee. Buy fruit before boarding; station kiosks close early.
Most crossings now happen without waking anyone. Keep your ID within reach anyway, and do not pack it at the bottom of the bag.
Morning arrivals are often half an hour late. Plan the onward train with at least an hour of slack, and check whether the ticket allows the next departure.
Updated occasionally.
