In 1871, Charles Brown founded the Schweizerischen Lokomotiv and Maschinenfabrik (S.L.M.) in the Swiss town Winterthur. Brown already had a great deal of experience with steam engines when he built his first steam-powered, three-wheeler in 1886. The steam engine had a total of six burners, but it still took half an hour before sufficient pressure had built up to move the vehicle. Once it got going, it reaches a top speed of 6 mph (10 kph). S.L.M. built just one passenger car. From then on they specialised in trucks.
