Adolf Schübler , from 1892 von Schübler , (* July 20, 1829 in Stuttgart ; † January 14, 1904 there ) was a German railway engineer.

Life

Adolf von Schübler was born as the son of the Württemberg mountain ridge and Münzwardein Valentin von Schübler . After attending grammar school in Stuttgart, he studied mechanical engineering at the Stuttgart Polytechnic and Karlsruhe Polytechnic from 1846 . In 1849 he became a member of the Corps Franconia Karlsruhe . Ferdinand Redtenbacher was one of his academic teachers who shaped him in mechanics and construction technology. In spring 1851 he passed the first state service examination in Württemberg. In the following years he first gained practical experience in the construction of the Bietigheim-Bruchsal railway line with the Bietigheimer railway viaduct and as a construction manager for the construction of the Flawil-Oberuzwil railway line of the St. Gallisch-Appenzell Railway and trained in rail technology by traveling to France and Belgium. In the spring of 1857 he passed the second state service examination in the subject "Hydraulic, Road and Railway Construction" and in the same year published a book with Friedrich Laissle on bridge girders, where she and others a. expand the beam theory - in particular derive the formula for determining the shear stresses .

In the following two years he was responsible for the construction of iron lattice bridges over the Eipel and the Gran in Slovakia, which at that time belonged to Hungary, as an authorized representative of the Biedermannsdorf machine factory .

In 1859 he joined the Württemberg railway service as a railway operations construction inspector in Esslingen am Neckar . In 1865 he left Esslingen at his own request to work as a railway construction inspector in Blaubeuren and Waiblingen on new state buildings.

After the Franco-Prussian War , Schübler moved to the Reichsdienst in 1872, initially as a laborer and from 1873 as railroad director and member of the Imperial General Management of the Railways in Strasbourg. There he initially carried out extensive additions and extensions to the Reichsbahnen and the leased lines of the Wilhelm-Luxemburg-Eisenbahn . This included the expansion of the railway stations in Mulhouse , Strasbourg , Metz-Sablon-Montigny and Luxembourg, including the associated workshops. He then headed the technical department for the northern inspection and management districts of Luxembourg , Metz and Saargemünd of the Imperial Railways in Alsace-Lorraine . In this function he promoted the construction of the Luxembourg ore railways to Dudelange , Rümelingen , Deutsch-Oth and Redingen as well as the Lorraine railroad into the Algringer Valley. In Alsace, he had 45 km of branch lines built. His last and most important project was the realization of the 75 km long Vosges Railway Mommenheim-Saargemünd , completed in 1895 , which connected the Saar area with the Rhine valley in a double-track expansion . Due to physical ailments, he retired on January 1, 1897.

In 1887, Schübler drew up a design for the renovation of Ulm Central Station , which was largely implemented. He emerged as a specialist writer of numerous papers on bridge construction and railways. In the obituary in the Zentralblatt der Bauverwaltung he was characterized as a "well-known and highly valued veteran of the railway industry".
