This ferry service no longer appears to be usable with the OSRM navigation service. When you start a route from Den Helder, with Texel as the end point, the ferry service is not seen as a possible route. This does work with Terschelling, for example. I myself cannot discover what goes wrong on the "way".

This path is now not available through a tool such as OSRM. It seems likely because it is a service way. By the way, more "ways" in the environment do not seem to connect now.
