Anyone knows what it is ?

[class ep-09]

While travelling abroad I saw tracks / rails having something connected to them between sleepers .
Those bits appear to be in place for certain distance ( few hundred yards ) followed by “normal” looking rails / sleepers .

Does it have anything to do with ETCS / ERTMS ?

It’s a noise and vibration suppression system, having put the photo into Google image search:

Starting in 2018, rail damper of type VICON AMSA had been installed in the German river valleys of Rhine, Elbe and Inn. At an overall length of more than 100 track kilometers the noise of passing trains will be reduced. For both the railway lines’ residents as well as the train passengers, it is important that the existing lines are not completely ‘tunneled’ by high noise walls.

Within special program funding, the infrastructure manager Deutsche Bahn has decided to use this smart way of noise reduction. The damper installation was executed, together with different track working companies, in challenging short track closing periods.
