To mark world sleep day, Caledonian Sleeper has released a 10-hour ASMR inspired sound track bringing the calming rhythm of its iconic overnight train journeys into homes across the UK.

The recording charters the Caledonian Sleeper’s route through Scotland, over a tranquil twilight descent, to the bustling sounds of a vibrant city.

There is no better time of year to take a sleeper train. Author and seasoned sleeper train passenger Freya Bromley offers her guide to what to book and why to love this gentler way to travel.

After a disappointing experience on the Caledonian Sleeper, I was apprehensive about the SJ night train from Stockholm to Kiruna.
