Kunze-Knorr brake

Kunze-Knorr goods train brake (diagram)
Bruno Kunze (1854–1935)
Georg Knorr (1859–1911)

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.
