In short: Operating since 1873, the Caledonian Sleeper is one of only two remaining overnight rail services in the United Kingdom. Each night, trains depart London Euston, splitting into multiple portions across Scotland to reach destinations like Aberdeen, Fort William, and Inverness, showcasing a sophisticated logistical operation that has evolved over 150 years.

The history of sleeper travel in Britain began on 24 February 1873, when the North British Railway launched the first sleeping car between Glasgow and London King's Cross. By October of that year, the rival Caledonian Railway introduced its own service via the West Coast Main Line, charging ten shillings for a berth. While sleeper services once spanned a vast network under British Rail, including routes from Bristol and various Scottish hubs, the late 20th century saw a significant decline. By May 1988, all East Coast sleeper routes were withdrawn, leaving the West Coast Main Line as the primary corridor for these overnight journeys.

The modern Caledonian Sleeper operates as a complex, multi-part service. The Highland Sleeper departs London Euston and divides at Edinburgh into three portions for Aberdeen, Fort William, and Inverness, while the Lowland Sleeper splits at Carstairs for Glasgow and Edinburgh. This process requires precise coordination; for instance, the Highland service uses electric Class 92 locomotives for the southern leg, which are then replaced by diesel Class 73/9 locomotives for the final stretches into the Scottish Highlands. In 2019, the service introduced a new fleet of Mark 5 carriages, replacing the aging British Rail-era stock.

The service has undergone numerous ownership changes, transitioning from British Rail to private operators like National Express, FirstGroup, and Serco. Following a period of private management, the Scottish Government took the service into state ownership in June 2023 through Scottish Rail Holdings. Despite its historical significance, the operation has faced challenges, including industrial action, technical delays during the 2019 rollout of new carriages, and a 2019 safety investigation by the Rail Accident Investigation Branch regarding brake control after train splitting. Today, the service continues to adapt, with plans to include stops at Birmingham International by January 2026.
