The german island Sylt can only be reached (for cars) on the shuttle train (www.syltshuttle.de).
So for now our maps can't route to sylt, because we don't route over railway=rail (even if it's tagged with motorcar=yes).
If I look to my Nüvi with Garmin City-Navigator Map, the way looks different than a normal rail-line, so garmin seems to have a special data type for this kind of connection.
So, how to handle this? Should we add a rule to the default style to route cars over railway=rail if it is tagged additionaly with motorcar=yes ?
I played a little bit and have found that it is not sufficient to map railway=rail + motorcar=yes to a routable garmin way. Because the car on the train can leave the train on every railway_crossing (crossings of railways with highways). :-) So I see 2 solutions: Map this beast with a new way (railway=shuttle or something like that). What is the correct english translation for this kind of trains transporting cars? Or implement a mkgmap option to unglue railway_crossings. Chris
