Yes, the Caledonian Sleeper offers on-board Wi-Fi, most reliably in the Club Car and the en-suite rooms, along with power sockets and USB charging so you can keep devices topped up overnight. In practice, treat the connection as a bonus rather than something to depend on. The train travels through remote parts of Scotland — including large stretches of the Highlands with little or no mobile coverage — so the Wi-Fi and mobile signal can drop out for long periods, particularly on the northern routes to Fort William, Aberdeen and Inverness. It's fine for messaging, light browsing and email when in range, but not something to rely on for video calls, streaming or heavy work through the night. If staying connected is essential, download anything you'll need before you board and don't count on uploading large files en route. Seated guests and Classic Room passengers have more limited facilities than Club and Caledonian Double guests, who get the fullest access including the Club Car. The bottom line: Wi-Fi exists and there's charging at your seat or in your room, but for an overnight journey through the Highlands, plan to be offline for part of the trip.
