Rail monitoring with accelerometers for bogies

One of the all-time challenges of the railway industry is to be on time. Commuters always complain if the train is late, delayed or cancelled. Businesses also depend on timely, effective delivery of their goods. Add to these challenges the demand for high-speed trains, more coach car seating, better riding comfort, fast internet connection and railway infotainment, excellent HVACR and hygiene facilities, all while ensuring safety and lowering CO2 emissions.

These demands puts pressures on the supply chain, railway infrastructure and on every component in a railway vehicle. One of these components is the bogie that is subject to a harsh environment and must withstand heavy loads and absorb vibration.
