The iconic 4-car articulated Cartic-4 car carriers were built between 1966 and 1972 and lasted until the mid-2000s.  The Cartic-4 car carriers were developed jointly by BR and Ford and adopted a radical design at the time for freight stock – comprising a permanently coupled four-part vehicle in which the inner cars were linked via shared bogies on articulated joints.  The majority were built for private vehicle transporters MAT, Silcock & Collings and Tolemans, however some were also built by BR and used to launch its Motorail brand in 1966. This offered motorists the opportunity to take their car on holiday with them, with an extensive network of services between cities including London, Birmingham and Sheffield and Scotland, the South West and North Wales. Once Motorail stopped the Cartic-4s were used to transport cars around the country both in block flows from factories to delivery points and in Speedlink flows to dealers.
