Kiev Express — one of The best European sleeper trains
The Kiev Express carries passengers from Warsaw, Poland to Kiev in the Ukraine, with options to sleep in a three-person compartment, double sleeper or single.
It takes over 17 hours and there’s no food available, so another service where it’s worth stocking up before you jump on board.
Still you get morning tea or coffee and a snack.
You can also travel within Poland on a few night services — from Swinoujscie, for example, to Warsaw.
