It is a complicated situation, the area is under construction. Two tunnels are being constructed under the railway. This reconstruction will take until 2026, so it will be subject to constant change. That there will be regular inaccuracies on OSM is inevitable.
Two notable issues. First, the map on Windows computer is different from the map on Android phone.
Second, where CT's cycle route deviates from the cycle path, it follows the route as indicated on OSM. Currently, however, this stretch of cycle path is as indicated on CT. Incomprehensible to me is how CT 'knows' the correct situation. Incidentally, in a few weeks, this too will be different.
Both screendumps where made this afternoon.
