Sunset onboard a Swedish SJ night train —
One of the finest ways to enjoy the vast expanses of Sweden (pictured) is while gazing out the window of a sleeper train at dusk. Though a number of operators continue to offer sleeper train service across Europe, competition from airlines and fast day trains is eroding their popularity.

'Hotel on wheels' —
The City Night Line is one of Europe's leading night train operators. It's like a "hotel on wheels," says Jeannine Kroggel, a supervisor on the Prague-Oberhausen, Germany route. "We have everyone, from Americans on a tour of Europe to German backpackers."

Long history —
Sleeper trains have been carrying passengers -- like these boarding the Prague-Oberhausen sleeper train at Berlin main station -- through European nights for almost 150 years.

Sleeping cabin services —
Each sleeping compartment is stocked with towels and toiletries, including this bijou mouthwash.

Deluxe living? —
First class sleeping cabins on the Prague-Oberhausen line come with their own shower and toilet.

Rhythm of the rails —
It's easy to fall asleep thanks to the click-clack sounds of the tracks. In the morning, passengers are served a pre-packed Czech breakfast of rolls, jam, cheese and coffee. Arrival in Oberhausen is at 8 a.m.

Declining passenger numbers —
Last year, Deutsche Bahn canceled both Berlin-Paris and Berlin-Copenhagen night routes, blaming declining passenger numbers.

No more cuts —
But DB says no further cuts are planned and the network is being improved to offer a cost-effective and comfortable service.

Final whistle for sleeper trains? Not quite —
Russian rail operator RZD has recently reintroduced two European routes. A sleeper goes from Paris to Moscow once a week and another sleeper links Moscow with Nice on the French Riviera.

Other European night trains —
There are still plenty of sleeper trains crisscrossing across Europe each night. Thello night train runs daily from Paris to northern Italy, stopping in Milan, Verona, Padua and, finally, Venice.

SJ night trains —

Disabled facilities onboard an SJ train —
The domestic SJ night trains run directly from Gothenburg to Ostersund and Lulea, from Stockholm to Ostersund and Lulea, and from Malmo to Stockholm.
