Railton was first Anglo-American hybrid
1930s car was a mating of fine English coachwork with a strong U.S.-made engine and running gear
The term hybrid now generally means a vehicle with both an electric motor and an internal combustion engine, with the engine as the primary power. But in earlier times hybrid referred to another type, a car from one manufacturer with an engine from another.
It often meant an English car with American power such as the Cadillac Allard, Nash Healey, Ford-engined Sunbeam Tiger or Hudson-engined Brough Superior. The car that started it, the first production Anglo-American hybrid, was the 1933 Railton powered by a Hudson Terraplane engine.
The Railton evolved from the Invicta manufactured by Invicta Cars of Cobham, Surrey, a specialist maker since 1925. It was known for fast, expensive, low-slung, sporty cars. When the depths of the Depression brought Invicta to its knees in 1933 it closed its Cobham facility and moved to Chelsea, London, where it carried on in a much smaller scale operation.
A new venture then replaced Invicta at Cobham. The initiators were Noel Macklin, a former principal of Invicta, and Reid Railton, the famous speed record engineer who designed Land Speed Record holding cars for both Sir Malcolm Campbell and John Cobb. He also created Campbell’s Bluebird II speedboat that held the world Water Speed Record for 10 years.
Macklin and Railton decided that mating fine English coachwork like the Invicta’s with a strong American engine and running gear would produce a spirited car. They would call it the Railton.
For power they turned to the low-cost American Essex Terraplane that had been introduced by Hudson in 1932 to cope with the Depression. It came initially with a 3.2 litre (193 cu in.) side-valve, 70 horsepower six, which was five more than Henry Ford’s new V-8. And since it was mounted in a lighter car it could outperform Ford’s more famous V-8.
In 1933, Hudson made a 4.0 litre (244 cu in.) 94 horsepower, inline eight available in the Terraplane. And while the Terraplane six was fast, the eight was even faster. It immediately began setting speed records, soon amassing over 50 American Automobile Association stock car records, including climbing Mount Washington and Pikes Peak. It also achieved 132 km/h (82 mph) on Daytona Beach.
The Terraplane-engined Railton emerged in 1933 looking very much like the Invicta. It came as a convertible coupe and touring, later expanded to coupes and sedans. A weight of just 1,134 kg (2,500 lb) and a 94 horsepower eight under the hood gave it excellent performance.
Contemporary tests indicated zero to 97 km/h (60 mph) in 10 seconds and top speed of 148 km/h (92 mph). This was quicker acceleration than any other English car and would have stood up well for many years after the Second World War.
Its top speed was challenged only by some more expensive marques like Lagonda, Rolls-Royce and Bentley. It was much faster than the SS, forerunner of the Jaguar, and became an instant favourite of the motoring press.
The fastest Railton was the rare cycle-fendered Railton “Light Sports,” of which only three or four were made. It weighed just 1,031 kg (2,100 lb) and was said to be capable of 172 km/h (107 mph).
The Railton custom-built body was mounted on a sturdy X-braced Terraplane frame with beam axles and leaf springs front and rear. Power went to the rear wheels through Terraplane’s manual, floor-shifted, three-speed transmission and Hudson’s oil-immersed “wet” cork clutch.
Railton made a small batch of 1933 cars with the 4.0 litre Terraplane eight, then for 1934 switched to the Hudson 4.2 litre eight which gave
113 horsepower and even more spirited performance. It became a favourite of Scotland Yard and other police forces.
Some 1934s got Hudson’s “Axle Flex” semi-independent, parallelogram type front suspension, but it could be troublesome and Hudson and Railton soon were back to solid axles.
Railton went into 1935 unchanged and produced 377 cars, its best year ever. For 1936 Railton got Hudson’s hydraulic brakes and a remote control shift lever that replaced the Hudson’a long wand.
From then on Railton seemed
to lose its way as a purveyor of fast, special interest cars. They got heavier and more expensive, with less to distinguish them from competitors like MG. By 1937 Railton was back to a Hudson six cylinder engine, and then toward the end, just before the Second World War, they were using 1.3 litre Standard fours.
Approximately a dozen Railtons were assembled after the war in Hudson’s Chiswick facility near London using pre-war components, but its time had passed.
Although several AngloAmerican hybrids like the Cadillac-Allard, Nash-Healey and Sunbeam Tiger would come along, the colourful originator of the genre had become history.
A revival attempt of the Railton name was made in 1989 with a car based on Jaguar components but it was not successful.
