lecture to the Royal Society in 1907 when it was shown running back and forth "on a taught and slender wire" "under the perfect control of the inventor". Brennan's reduced scale railway largely vindicated the War Department's initial enthusiasm. However, the election in 1906 of a Liberal government, with policies of financial retrenchment, effectively stopped the funding from the Army. However, the India Office voted an advance of in 1907 to develop the monorail for the North West Frontier region, and a further was advanced by the Durbar of Kashmir in 1908. This money was almost spent by January 1909, when the India Office advanced a further . On 15 October 1909, the railcar ran under its own power for the first time, carrying 32 people around the factory. The vehicle was , and with a petrol engine, had a speed of . The transmission was electric, with the petrol engine driving a generator, and electric motors located on both bogies. This generator also supplied power to the gyro motors and the air compressor. The balancing system used a pneumatic servo, rather than the friction wheels used in the earlier model. The gyros were located in the cab, although Brennan planned to re-site them under the floor of the vehicle before displaying the vehicle in public, but the unveiling of Scherl's machine forced him to bring forward the first public demonstration to 10 November 1909. There was insufficient time to re-position the gyros before the monorail's public debut. The real public debut for Brennan's monorail was the Japan-British Exhibition at the White City, London in 1910. The monorail car carried 50 passengers at a time around a circular track at . Passengers included Winston Churchill, who showed considerable enthusiasm. Interest was such that children's clockwork monorail toys, single-wheeled and gyro-stabilised, were produced in England and Germany. Although a viable means of transport, the monorail failed to attract further investment. Of the two vehicles built, one was sold as scrap, and the other was used as a park shelter until 1930. Scherl's car Just as Brennan completed testing his vehicle, August Scherl, a German publisher and philanthropist, announced a public demonstration of the gyro monorail which he had developed in Germany. The demonstration was to take place on Wednesday 10 November 1909 at the Berlin Zoological Gardens. Scherl's machine, also a full size vehicle, was somewhat smaller than Brennan's, with a
