can you really make that transfer?
When you're routing a train journey, often you will need to transfer at an intermediary station. Particularly with Deutsche Bahn delays, these transfers can get tight! BUT the planner doesn't actually know how tight it is. transfr reads the internal walkways in the station with OpenStreetMap and maps your path between the platforms. Unfortunately there's not quite enough data for this to actually be useful but it's kind of useful.
