From its first test in 2012 until today, Fiber Optic Sensing (FOS) in Railways developed rapidly. After the first permanent installation, beginning in 2014, Deutsche Bahn now owns four systems, more are planned, to test several applications and proof its usage in live operation.
Therefore FOS was installed in different locations to mainly proof the applications cable theft, rock fall and mud slide, track condition monitoring and noise measurement can be used live by the operators and maintenance staff. Further test weeks with focus on train tracking and security were added. The overall result: FOS is capable to deliver constant feedback from track and train condition through existing fibre cables along the track. And the information can be transferred and used directly by the responsible staff in different places all over the country, using a performant and scalable server behind. The only hurdle today with some applications is the detection rate which we and the DAS companies work constantly on to improve.
FOS is just about to get a substitute for different techniques and will soon add new features to the operation and maintenance process. The positive effects to quality, service and economic facts are already provable and will rise constantly. After the low hanging fruits, the non-SIL applications are picked, the SIL applications will bring the whole railway business to another level.
The journey starts today. Future speaks Fibre Optic Sensing.
