From March 2018 onwards, on completion of the test runs in Wegberg-Wildenrath, a field test will be carried out in the form of a demonstrator train. In order to obtain reliable information on the wear and cost-effectiveness of the innovative freight wagons/components, it is essential to aim for a high mileage within the scope of the field test. A schematic representation of the demonstrator train is shown in the following figure.


A field test will be performed in the form of a demonstrator train. A total of 23 freight wagons will be deployed, including 12 innovative freight wagons and 8 reference vehicles with conventional components; plus 3 existing freight wagons with automatic center buffer couplers The desired mileage is approx. 150,000 km over a trial period of approx. 10 months.

In order to test a range of configurations, one IFW of a specific wagon type is run fully laden, one IFW is run 50% laden and one IFW is run unladen. A reference wagon of each wagon type is run 50% laden and one unladen in order to achieve direct comparison values to the IFWs. The existing freight wagons with automatic couplers are run unladen.

The aim is to align the field tests closely with the test runs carried out within the scope of the “EuropeTrain” project. In the EuropeTrain project, a test train was run in different test loops through Europe for approx. 150,000 km in order to test the LL blocks. This enabled coverage of all relevant operational conditions for Europe, i.e. the EuropeTrain runs were carried out in different operating modes on a variety of gradients, under harsh winter conditions, high temperatures and in a range of different topographical areas (plains, mountains). For this purpose, the wagons were repeatedly run on 6 different test loops (Scandinavia, France, Germany, transalpine, Eastern Europe, Italy) and during different times of the year.

Deutsche Bahn AG was able to incorporate the data on wear values and acoustic measurement from the EuropeTrain project in the current research project. This enabled a comparison of the measured values of the EuropeTrain project with the measured values to be collected in the current project, thus providing a significantly bigger database for the feasibility studies than would otherwise have been available just from the field tests performed within the scope of this research project.
