that pedestrians and cyclists are often navigated along the Railway. On this location, there is no Way/Path/Road along. But you are guided along.
We asked people what they are using, and always they use Systems with OSM-based Maps. "OsmAnd", "Maps.me", "Navmii" and others but also a lot of build-in Programs in Bicycle-Computers.
I´m useing OsmAnd with default settings.
I wil try to document it, when it hapens again.
