Also, - netcheck only checks weak connectivity - netcheck ignores vehicle classes unless run with option --vclass. This can account for unreachable parts in your network despite there being only one component. The output of duarouter should indicate the vehicles that did not have a valid trip. You can investigate reachability from their respective depart edge by using the netcheck option --source
