Whisper rail.

The innovative Whisper rail, a continuously elastic bedded system, provides rail deflection of up to 10 mm. This high level of elasticity ensures vibration damping of up to 90% in the critical frequency ranges. That in turn means particularly good protection from shocks and structure-borne noise.
The Whisper rail consists of a flat-bottomed rail surrounded by elastomers. The encasing sections, which form a rigid boundary zone between the bedding and the road covering, allow the rail to move inside the construction.
The Whisper rail is available in two versions – one for open road cross-sections and the other for closed cross-sections. The rail top versions are suitable for open constructions or for track encased in vegetation. For closed road cross-sections the Whisper rail takes the form of grooved rail with the top end of the casing section forming the groove. Another system which is often used is the Ortec Whisper rail on Rheda City which is also available as a complete system.
