Wouldn’t it be possible to have nightline buses operating the same routes as the subway during that window? It works well e.g. in Berlin and Munich and only takes minimally longer than the train (since the roads are not congested at night and the bus can hence go much faster). At least it should be possible for a temporary maintenance window?
