During 1820s, Seguin brothers was a French firm well known for suspension bridges and steamboat navigation. In 1825, they started negotiations with French government for the construction of a railway line from the Saint-Etienne coal field to the Rhone Valley and The city of Lyon. During a long trip of 1825-26 in England and Scotland, they visited the famous first public railway of Stockton & Darlington and gathered much information about steam railway traction and locomotives as linked with railway line design. Their personal engineering and managerial background gave us a very good understanding of the British technological system for railways, and its tremendous potential for heavy transportation. Such understanding was not only a ‘copy’ by the way of buying materials, wagons, and locomotives, but also a critical reflection on the technical choices made by the British engineers. For example, they refused the common point of view of that time for the general design of a line, i. e., the primacy of fixed engines for inclined planes. This paper presents the development of locomotives of the Saint-Etinenne & Lyon railway (Le Chemin de fer entre Saint-Etienne et Lyon) form the viewpoint of its design, construction and first uses. Major points discussed include: 1) the two Stephenson's locomotives bought for this railway, 2) the first Seguin's French patent for the famous tubular boiler, 3) locomotive construction in Perrache, Lyon. This study highlights the originality of Marc Seguin's locomotives.
