The lines open in Germany three years before the Year of Revolution already stretched from Mannheim to Bale, 

 Stettin, Berlin, and Hanover to Dresden, and Prague to Wiener-Xeustadt, besides many shorter routes. M. Le Chatelier 

 was the inventor in 1863 of the ' Counter-Pressure Brake' for giving steam to the cylinder against the train, which 

 was the chief attempt to improve on the Aveak hand-brake before the Continuous Automatic Brake operated by a 

 vacuum or compressed air, the latter of which is now universal outside England and India.
