# British Rail Mark 5 (CAF)

The British Rail Mark 5 is the designation given to locomotive-hauled rail carriages built by Spanish manufacturer CAF for operation with Caledonian Sleeper.

## Description

In 2015, the Caledonian Sleeper service, which had formed part of the ScotRail franchise, was split into a separate operation, with Serco as the new franchise operator. As part of the franchise agreement, Serco was committed to procuring new rolling stock to replace the operation's existing fleet of Mark 2 and Mark 3 passenger coaches. In February 2015, Serco signed a €200m deal with CAF to purchase 75 coaches of five different types. These are formed into a total of four 16-coach trains (London Euston to Fort William, Inverness and Aberdeen, London Euston to Edinburgh and Glasgow, plus the two respective return services), plus two coaches for Fort William-Edinburgh-Fort William, with nine coaches as spares, and are hauled by Class 92 locomotives between London and Glasgow/Edinburgh, and Class 73s on unelectrified routes.
The new vehicles are the first new locomotive-hauled passenger coaches introduced onto the British network since the Mark 4 vehicles on the East Coast Main Line as part of the InterCity 225 sets in 1989–1992. The first five coaches began testing on the Velim railway test circuit in the Czech Republic in August 2017, before being delivered to Polmadie TRSMD in January 2018. Mark 5s commenced operating the London to Edinburgh and Glasgow services in April 2019, with the remainder converted in October 2019.

## Specifications

In accordance with the Scottish Government Caledonian Sleeper franchise agreement, Serco's order for purpose-built sleeper rolling stock from CAF originally specified six different types of vehicles to accommodate onboard services and accommodation types. These included a separate lounge car, seated car, hybrid pod / sleeper car, pod car, PRM sleeper car, and regular sleeper car. However, due to safety concerns later arising over aircraft style "pod" seating being incompatible with railway crash worthiness regulations, Serco opted to modify the Mk5 order by requesting that both dedicated and hybrid pod coaches instead be constructed as regular sleeping vehicles.
