Railton Mobil Special

The Railton Mobil Special, previously known as the Railton Special, was the chief rival to the Thunderbolt in the 1930s. Pilot John Cobb has engaged with a fierce rivalry with Captain Eyston of the Thunderbolt, and both men where able to secure landspeed records during their speed battles. Powered by two supercharged Napier Lion VIID W12 aircraft engines, the Railton Mobil Special was the first vehicle to break the 350 miles per hour barrier. After World War II, Mobil Oil took up sponsorship and helped with a redesign, ultimately leading to the vehicle reaching a top speed of 394.196 miles per hour in 1947.
