Where do trains sleep at night?

At night, trains do not sleep wrapped in a giant blanket. But stations and depots are transformed into giant dormitories for rail vehicles. Trains await daybreak inside the station or terminal, in the depots, where automatic alarms may start warming up the machine before departure (mainly for metros), in sidings next to the depots, or in tunnels in winter, for protection against cold and frost.
