A further business interest of Gardner-Serpollet was in railway steam-cars, which they named 'autonomobile' carriages, and in December 1902 and January 1903 it was widely reported that three of the new powered carriages were scheduled in June 1903 to run from Paris to Dijon at 100 km/hour. However, there appears to be no records to confirm this happened.

290:, and at the same time he continued to develop the flash steam concept with his brother by post. In 1886 the two brothers arrived at their best design of flash steam boiler, and then shortly afterwards they went into business building flash steam boilers, initially small scale to power lighting systems and pumps, but soon to power tricycles and steam boats, and eventually to cars, trams, and buses.

for the steam engines of the time. In addition flash boilers needed a sophisticated control system to ensure the water injected to the boiler and the heat from the burner matched, and that the steam produced matched the demand of the engine. In addition to the control system, Léon also had to devise a better steam engine design suited to very high pressure steam, using

commercial vehicles used the double-acting two cylinder version of the
Serpollet patented engine design. Unfortunately, in the autumn of 1906 Leon Serpollet developed symptoms of a serious illness, dying in February 1907, and this had a major impact on the business, which has been at the time transitioning from the old works of M. Serpollet to a new factory.

The
Metropolitan Steam Omnibus Company ceased using its Darracq-Serpollet steam buses on 16 October 1912, but many buses were sold on and used elsewhere. AH Creeth & Sons of the Isle of Wight acquired its first Darracq-Serpollet steam bus in 1909, and went on to acquire 3 more, reputed to be the

Company. The performance of the cars they produced was very competitive against the internal combustion engines of the time. For example, at the

Auguste Serpollet. He went into the family business with his brother Henri (1848–1915) producing circular saws and wood working machines. It was when seeking to power their workshops that Henri came up with the idea of flash steam generation, with a

Darracq-Serpollet were not purely omnibus builders, and at the commercial motor show at
Olympia in 1908 they exhibited a new 12-15 hp chassis suitable for light vans, a 30-40 hp bus or lorry chassis, the same chassis fitted with a 3-ton van body (by Liversidge), a 30-40 hp lorry with

The key characteristics of flash steam boilers stem from the fact that there is very little water in the boiler at any moment, which leads to fast startup, and minimal explosion risk - they also provide high steam pressures and temperatures which can give high thermal efficiency, but were not ideal

Leon
Serpollet died aged 48 of a 'malignant disease', and with his passing the interest in steam cars seemed to wane, especially in France, there were no steam cars on show at the Paris Salon automobile show of 1908. His influence on the automotive industry had been substantial as stated in many

In the 1890s Léon
Serpollet was involved in applying his flash steam boiler to tramcars. In January 1897 he entertained a deputation from Aberdeen at his depot in Willesden, London, where he displayed a 4-seater Phaeton, and a double-decker steam tramcar for 50 people running on a test track. A

The new factory was in use by late 1907, and many buses were made, notably for the
