MONITORING INSTRUMENTS MOUNTED ON SCHEDULED RUNNING COMMERCIAL TRAINS (INSTRUMENTED REVENUE VEHICLES, IRV) MAKE USE OF NEWTON`S LAWS OF MECHANICS FOR TRAIN BASED AND IN-SERVICE TRACK-CONDITION MONITORING IN TARGET PLANING OF MAINTENANCE

The Newton`s Laws Mechanic is useful to analyse mutual track-vehicle/wheel-rail interactions and to determine track irregularities and track defects by vehicle mounted instruments: Accelerometer Sensors and Gyroscope Devices for Rotation Measurements. This means, by measuring accelerations and rotations through instruments on board of commercial and scheduled running rail-vehicles, the cause in form of track irregularities can be determined. And by continuous track monitoring with repeated runs over the same track, the development of track-defects and track-irregularities, the development over the time of such defects and irregularities, in other words, the Track-Deterioration Rates or Velocity of Deterioration, can be measured, and the threshold for necessary interaction by repair, maintenance or renewal can be forecasted.

Automatic in-service track-condition monitoring through Instrumented scheduled running commercial Revenue Rail-Vehicles (IRV), making use of NEWTON`S LAWS OF MECHANICS, drive track maintenance efficiency.

Continuous monitoring collects up-to-date dynamic responses, which together with historical data can assist in predicting future deterioration for each section of track (= predictive condition monitoring). Based on the IRV feedback, scheduled maintenance activities can be prioritized at locations exhibiting rapid deterioration.
