The First World War (1914-18) brought permanent change to Brooklands in many ways.

Motor Racing was discotinued for the duration of the war but the solid tyres of military lorries played havoc with the Track, and it was not until 1920 that Locke King had cleaned up sufficiently to enable the BARC to take over once again.

Brooklands started to liven up in 1921, the same year as the first of the Junior Car Club's famous 200 mile races. Pre-war driver, Malcolm Campbell, returned to the scene from Army service as a Captain and the race was a huge success.The winner was another star driver, Major Henry Segrave.

In August 1926 the RAC organised the first-ever British
Grand Prix constructing sand chicanes and a somewhat hazardous bridge across the Finishing Straight. The same features were utilised for the Junior Car Club 200 mile race later that year. Once again, the race was won by Major Henry Segrave in a Talbot.

The same year Hugh Locke King died but Ethel, now a Dame of the British Empire in honour of her work in the Red Cross during the war, continued active management of the Brooklands Estate. She also regularly attended Race meetings.

The last Land Speed Record achieved at Brooklands was when Kenelm Lee Guinness, a member of the famous brewing family, drove the 350hp single seater Sunbeam at a two-way average speed of 135.75mph. This car, powered by a V12 Sunbeam 'Manitou' aero engine was soon after acquired by Malcolm Campbell and became his first 'Blue Bird' Land Speed Record Car.

Count Louis Zborowski was one of the great personalities of Brooklands and raced a series of monstrous cars on the Outer Circuit, including the legendary Chitty Bang Bangs, in the early 1920s.

Based in their Brooklands workshops, Thomson & Taylor went on to design and build several Land Speed Record cars including three of Malcolm Campbell's Blue Birds. It was Campbell that called in Reid Railton to re-design the chassis and transmission of his 1931 Napier engined Blue Bird. The body shape resulted from testing in the Vickers aircraft factory's Wind Tunnel at Brooklands supervised by R.K. Pierson, Vickers' Chief Designer, as he had with Campbell's first scientifically streamlined Blue Bird in 1928.

In 1933 Thomson & Taylor made more major changes to accommodate a supercharged Rolls Royce 'R' type 36½ litre V12 engine giving 2,500 brake horse power.

Campbell's ultimate Land Speed Record car was the 1935 Blue Bird using the same engine but a new chassis designed and built by Thomson & Taylor at Brooklands. The body was built in the Paddock shed once used by Malcolm Campbell as his showroom. In this car Campbell took his eighth and final Land Speed Record on the 3rd September, 1935 on Bonneville Salt Flats and achieved his longed for target, averaging 301.13mph.

By the end of the 1930s Brooklands was dominating the Land Speed Record in every way with the exception of actually being the venue itself.

Another Land Speed Record Car simply called 'The Railton' was a technological masterpiece designed by Reid Railton and built at Thomson & Taylor's Brooklands workshops. It was commissioned and driven by the Brooklands ace, John Rhodes Cobb, who took the Land Speed Record in it in 1938, 1939 and again in 1947 when he became the first man to exceed 400 mph on land.

The Outer Circuit Record was the most prestigious. In 1930, The Daily Herald put up a trophy for the fastest driver round the track. Up to 1935, this trophy was won by just 4 drivers, Kaye Don, the first winner, battled with Tim Birkin to achieve 137.58mph in his Sunbeam 'Tiger'. In 1932, Tim Birkin took the record to 137.96mph in his famous red blower Bentley.

It was, however, John Cobb who finally took the record to 143.44 mph in his Napier Railton. Regarded as the ultimate Brooklands Racing Car, it was designed and built by Thomson & Taylor in their premises in the Brooklands Aero Village. It is seen here outside their workshops being test driven for the first time in 1933. Powered by a 24 litre Napier Lion engine, the car’s Outer Circuit record remained unbeaten when racing and record breaking finished at Brooklands in 1939.
