A Network of trains with sleeping cars operates daily between London and Scotland (Caledonian Sleeper), and between London and the West Country as far as Cornwall (Night Riviera). Using rolling stock designed and formerly operated by British Rail, these services offer single or double– occupancy bedrooms. These services operate all week, except Saturdays and usually depart London (Euston and Paddington) in the evening, arriving at their destinations at approximately 08:00. Both Services use British Rail Mk3 sleeper coaches although the Caledonian sleeper is having their coaches replaced with Mk5 coaches.
