ASC IMUs enable efficient switching of freight trains

The purpose of the research project SAMIRA is to develop a driver assistance system that will simplify the time-consuming process of switching freight trains. The high-precision ASC IMU 7 plays a central role in the project: It continuously transmits the exact position of the train to the locomotive switcher. The long-term objective is to achieve fully autonomous switching operations.

In the past, switching of long freight trains was carried out as a two-man operation. This is because one-man operation is very time-consuming due to the long walking distances involved; remote controls would not ensure the necessary safety. The problem: shortage of personnel, which is compounded by the competitive disadvantage that freight trains are slower than trucks.That is why the EU-subsidized SAMIRA project is researching a driver assistance system that will make freight transport more efficient. It consists of an electronic camera and sensors at the end of the train. They allow the driver of the locomotive switcher to see the end of the train from the cab, so that he no longer has to walk long distances and can carry out switching of the trains alone.The ASC IMU 7 ensures that the locomotive driver knows the exact position of his train at all times. The unit, which was developed for high-precision navigation of vehicles, constantly monitors their position with its six degrees of freedom. The Aachen University of Applied Sciences, ARIC GmbH and RheinCargo expect the assistance system to be ready for market launch by 2022.
