AMRA – Asset Monitoring for Railway Applications


Condition monitoring of freight cars


Bosch has taken the principles and technologies of the Internet of Things and applied them to rail freight transport. On behalf of Bosch Engineering GmbH, Bosch Software Innovations is developing a solution for condition monitoring of freight cars. This means Bosch Software Innovations is responsible for developing the software backends, the user portals, and their interfaces. The company will also be in charge of connecting the various devices and seamlessly integrating the data into the users’ IT systems.

The overall solution, AMRA (Asset Monitoring for Railway Applications), uses data from various sensors in compact and robust housing affixed to freight cars. The acquired data, such as mileage, vibration, position, temperature, and air humidity, can help realize important applications and benefits for rail freight transport.



  • Greater fleet efficiency due to reduced throughput times.
  • Improved availability thanks to condition monitoring.
  • Reduced costs by avoiding consequential damages.
  • Improved transportation quality thanks to goods monitoring.
  • Improved logistics through integration into the supply chain.
  • Easy expansion for future applications thanks to standardized interfaces.

Use cases


Position tracking:

Integrated GPS sensors transmit the car’s location at all times. This avoids losses, simplifies planning, and improves wagon rotation.

Mileage counter:

Maps of the rail network, in combination with geographical data and route planning, supply precise data regarding how far the car has traveled. This can help define maintenance intervals more reliably and transmit them to a condition-based maintenance system.


Vibration monitoring:

A three-axis vibration sensor measures and analyzes the strength of vibrations that occur during loading, unloading, and maneuvering goods. This allows users to detect the causes of potential damage to the car and the freight early on.

Monitoring defined areas:

Active alerts are triggered when the car leaves a defined area of operation. This makes it easy to determine costs of idle time, accelerate travel times, and improve fleet efficiency.


Freight monitoring:

Sensors in the freight car record temperature and humidity values. The results are processed in a transparent way and can be evaluated either for individual points in time or for the entire route.
