There is a specific happiness that begins when the platform lights start to slide past the window and your bed is already made. Night trains are back on the timetable, and I have been collecting them.
What the sleeper gives you
A day not lost to an airport. A city that begins at sunrise, before the crowds. And the small ceremony of a paper cup of coffee handed to you as the border goes by.
Book the bottom bunk, pack earplugs, and keep the blind up an hour longer than is sensible. Some of the best scenery works a night shift.
