Development
After the Prussian steam locomotive classes S 4 and S 5 proved less than fully satisfactory, there was a requirement in Prussia for faster and more powerful express locomotives. To that end the Head of the Locomotive Design and Procurement Department, Robert Garbe, proposed to the Locomotive Committee in 1904 a design by Linke-Hofmann of Breslau for a 4-4-0 superheated, express train locomotive. This was an evolutionary development of the Prussian Class S 4 that also had a 4-4-0 configuration. In putting this forward, Garbe was especially keen to prove the superiority of his design compared with the four-cylinder, wet steam, compound locomotives, particularly its predecessor, the Prussian Class S 7.
In 1905/1906 Garbe pushed through the construction of the S 6. Between 1906 and 1913 a total of 584 units were manufactured by Linke-Hofmann, Henschel-Werke and the Maschinenbauanstalt Humboldt in Cologne. They were the last four-coupled, express locomotives to be built in Germany and, for a long time, were the most economical locomotives in the Prussian state railways.

Famous quotes containing the word development:
“A defective voice will always preclude an artist from achieving the complete development of his art, however intelligent he may be.... The voice is an instrument which the artist must learn to use with suppleness and sureness, as if it were a limb.”
—Sarah Bernhardt (1845–1923)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“John B. Watson, the most influential child-rearing expert [of the 1920s], warned that doting mothers could retard the development of children,... Demonstrations of affection were therefore limited. “If you must, kiss them once on the forehead when they say goodnight. Shake hands with them in the morning.””
—Sylvia Ann Hewitt (20th century)
