MECHANICAL SKID PREVENTER WITH NEW CONTROL METHODS--KNORR SYSTEM

A few years ago during a damp and foggy autumn with particularly heavy fall of foliage, the rail adhesion coefficient on gradient sections of the DB fell to about zero and in one case resulted in a fatal accident. The experience showed that there was room for improvement in the anti-skid equipment employed, and the DB's Central Office in Minden (Westf) was instructed to examine the matter in conjunction with Knorr-Bremse GmbH of Munich and provide a remedy. In the course of the subsequent investigations Knorr developed the mechanical skid preventer described here. According to the test results it can guarantee security in braking even under the most adverse weather conditions.
