Monitoring of components on trains and rails

One single solution for tracks and trains: Frauscher Tracking Solutions FTS combines DAS technology and wheel detection systems, forming a powerful complete system. This facilitates new possibilities for monitoring even complex railway networks.

Smooth railway operations depend on maximum availability across the entire infrastructure. Therefore consistent monitoring of every component on all trains and tracks is needed.

Today, a wide range of monitoring systems is available that provides various solutions to this requirement. These highly specific systems, e.g. for wheel flat or hot box detection, allow for punctual monitoring of train components. Precise wheel sensors with high availability from Frauscher are frequently used to trigger appropriate track side equipment for measuring and monitoring. Due to this, our company has been able to acquire comprehensive knowledge on carrying out such applications during recent decades.

Detecting events all along the track

In light of these experiences, the newly developed Frauscher Acoustic Sensing FAS provides an ideal solution, as it enables monitoring of both trains and infrastructure components.

By using FAS it is possible to monitor whole railway networks including their complete environment. Even events which are unforeseeable and hard to detect are tracked in a reliable way. This includes rail breaks, which are known to be a major risk along the track. The system also detects catenary flash-overs, floods, rock and tree falls as well as landslides. This enables a significant reduction in the number of highly expensive operational restrictions.

Rail breaks and wheel flats have already been detected successfully in initial test installations.

Minimising costs – maximising the output

DAS based Frauscher Tracking Solutions FTS offer a solution to monitor an operator’s complete infrastructure in real-time. So far, we have developed a range of prototypealgorithms to detect and classify specific events, including rail breaks and loose track joints as well as vibrations from catenary flash-overs, rockfalls and landslides.

Combining this new approach with proven wheel detection systems also enables monitoring of components mounted on trains as well as precise localisation of detected events. For this purpose signals from FAS are extended by data from wheel sensors and evaluation boards. These include precise position of the first and the last axle of a train. On that basis, a train can be uniquely assigned to a track and its length can be determined more exactly.

By merging and overlaying signals from both systems, it will be possible to precisely localise status information from train components – such as wheel flats that can then be assigned to a specific axle. This allows for the use of FAS within complex railway networks that include numerous lines running in parallel and connected by several switching points.
