The Railton Special, later rebuilt as the Railton Mobil Special, is a one-off motor vehicle designed by Reid Railton and built for John Cobb's successful attempts at the land speed record in 1938.
The vehicle was powered by two supercharged Napier Lion VIID (WD) W-12 aircraft engines. These engines were the gift of Marion 'Joe' Carstairs, who had previously used them in her powerboat Estelle V. Multiple engines was not a new technique, having already been used by the triple-engined White Triplex and the Railton Special's contemporary rival, Captain Eyston's twin-engined Thunderbolt. With the huge powers thus available, the limitation was in finding a transmission and tyres that could cope. Reid Railton found a simple and ingenious solution to this by simply splitting the drive from each engine to a separate axle, giving four wheel drive.

The vehicle weighed over 3 tonnes and was 28 feet 8 inches long, 8 feet wide, and 4 feet 3 inches high. The front wheels were 5 feet 6 inches apart and the rear 3 feet 6 inches. The National Physical Laboratory's wind tunnel was used for testing models of the body.
