Kunze–Knorr Brake
The Kunze-Knorr brake (''Kunze-Knorr-Bremse'' or ''KK-Bremse'') is an automatic compressed-air brake for goods, passenger and express trains. It was the first graduated brake for goods trains in Europe. When it was introduced after the First World War, goods train brakes switched from hand operation to compressed-air in various European countries. The Deutsche Reichsbahn alone put the cost of equipping German goods wagons with Kunze-Knorr brakes between 1918 and 1927 at 478.4 million Reichsmarks. The operating cost savings from faster goods services and having fewer brakemen was assessed by the Reichsbahn at almost 96.3 million Reichsmark annually. Inventors The Kunze-Knorr brake brought together the ideas of Prussian senior surveyor, Bruno Kunze (1854–1935), and preparatory work by the founder of Knorr-Bremse, Georg Knorr (1859–1911). It was the first, continuous, compressed-air brake that, even on long goods trains, enabled the brake force not only to be applied gradually ...

Railway Brakes
A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains. Early developments In the earliest days of railways, braking technology was primitive. The first trains had brakes operative on the locomotive tender and on vehicles in the train, where "porters" or, in the United States brakemen, travelling for the purpose on those vehicles operated the brakes. Some railways fitted a special deep-noted brake whistle to locomotives to indicate to the porters the necessity to apply the brakes. All the brakes at this stage of development were applied by operation of a screw and linkage to brake bloc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Rail Transport In Germany
The history of rail transport in Germany can be traced back to the 16th century. The earliest form of railways, wagonways, were developed in Germany in the 16th century.

This had been preceded by the opening of the horse-drawn Prince William Railway on 20 September 1831. The first long-distance railway was the Leipzig-Dresden railway, completed on 7 April 1839. Forerunners The forerunner of the railway in Germany, as in England, was to be found mainly in association with the mining industry. Mine carts were used below ground for transportation, initially using wooden rails, and were steered either by a guide pin between the rails or by flanges on the wheels. A wagonway operation was illustrated in Germany in 1556 by Georgius Agricola (image right) in his work '' De re metallica''. This line used "Hund" carts with unflanged ...
