COMPARISON OF RAIL SUPPORT SYSTEMS IN UNDERGROUND RAILWAY LINES - REDUCTION OF STRUCTUREBORNE SOUND

In the Cologne U-Bahn system the concept of ballastless and sleeperless track has been employed for many years. The rails are in the main mounted on elastomeric point supports. This system of rail mounting has recently been improved. In order to clearly measure the vibration reduction provided by the new rail support, called the "Cologne Egg" , different rail supports were mounted one after another for measurements on the same section of track. This provided the opportunity for measurements to be carried out where all other influences could be kept constant, e.g. tunnel construction, route selection, vehicle type, operating conditions, track conditions and measurement conditions. This paper discusses design of the elastomeric rail support systems, the measurement program and its results.
