1 +The REAKT project (https://reakt.sh/ & https://www.schiene-m-l.de/) aims at developing new mobility concepts to reactivate rural rail lines. This project will evolve around developing an autonomous rail vehicle, the **REAKTOR**, to flexibly provide on-demand service on single track lines. A prototype will be build in 1:32 scale for 45 mm gauge, as well as a full scale version for the railway track Malente-Lütjenburg.

5 -* Develop and implement and algorithm for computing a best-effort projection of a vehicle position on a track
6 -* Evaluate the algorithm (and potential variations) with the real-world data collected in the Malente-Lütjenburg track
