There currently is one option to travel by night train from Edinburgh (United Kingdom) to London (United Kingdom), taking between approximately 8 and 10 hours: Namely the Lowlander SB (E) operated by Caledonian Sleeper.
The Caledonian Sleeper connects London with various destinations in Scotland and offers a comfortable overnight travel option. The train provides comfortable sleeper cars, but also seats for budget-conscious travelers. There are basically two lines: the Lowlander and the Highlander. The Highlander travels further into northern Scotland while the Lowlander serves destinations including the Scottish metropolis of Glasgow.
The train offers three types of sleeper compartments: Classic Room (entry-level with bunk beds and washbasin), Club Room (like Classic, but with private toilet and shower) and Caledonian Double (luxury class with double bed and private bathroom). For those who want to travel at lower cost, seating cars are also available.
With the Club Car, the Caledonian Sleeper has a restaurant car offering an extensive selection for dinner and breakfast. Particularly popular is the Traditional Scottish Breakfast with eggs, bacon, baked beans, haggis, and black pudding. Passengers in higher categories have priority during busy times and their breakfast is included.
Yes, in the Classic Room, adjacent compartments can be connected by a connecting door to form a sort of suite. This is particularly convenient for families with children. Additionally, each part of the train typically includes an accessible sleeper car with wheelchair-friendly compartments.
The Caledonian Sleeper also offers seating cars as the most economical option. Prices start at less than 100 euros, while a sleeper car is significantly more expensive. The seating cars are particularly interesting for budget-conscious travelers and those with bicycles, as bicycle spaces are available here.
Regarding sanitary facilities, all sleeper compartments have at least a washbasin. Club Rooms and Caledonian Doubles go beyond this and feature a private bathroom with toilet and shower. Travelers in Classic Rooms use the shared toilets at the end of the car. The train also includes accessible compartments with adapted sanitary facilities.
