“Since October 2018, RATP and SISGEO have collaborated by carrying out several test campaigns for the development of an automatic instrument for measuring the vertical displacement under load of the track frame, more commonly called” dance “.

SISGEO has been able to meet our expectations by developing a reliable measuring instrument resistant to the constraints of the RATP RER railway environment.

After this very special year 2020, the industrialization of this instrument scheduled for early 2021 will provide a first innovative solution expected by the rail sector to optimize track maintenance and, more generally, to contribute to improving traffic safety.”
