The Queens-bound (7) is one of, if not the oldest routes for the NYC Subway, dating back to at least 2000. Also, it was created for BVE1, which severely limited the amount of objects one could place on a route. Forgive the inaccuracies for this route as well as the other legacy routes.
To my knowledge, no one's making the Queens-bound version, but, as has been previously stated, the Manhattan-bound version is under development. No, we don't know when it will be released so please don't ask.
