- Made:

- maker:
- Louis Brennan
Model Gyroscopic Mono-Rail car, scale 1:8, built by Brennan.
The inventor Louis Brennan (1852-1932) built this working model in about 1907 to demonstrate his ideas for a single-tracked rail vehicle stabilised by two linked gyroscopes. Brennan's daughter became a guinea-pig and was enlisted to help him conduct tests and demonstrations to prove the stability of his invention.
Brennan had patented the Gyroscopic Mono-Rail design in 1903 and was commissioned by the United Kingdom's War Department to create a full size prototype. He built his full size version in 1909, and it was 40ft long, weighed 22 tons and could carry a load of up to 15 tons. Demonstrations to the Press took place as well as an exhibition at the White City in 1910, where fifty passengers were driven around a circular track - one of the passengers was Winston Churchill who showed considerable support for the invention. Despite this, investers were not convinced and the Mono-Rail was not adopted.
