Yes, 66 was the only route replaced, with some associated changes to Routes 425, P426, 430, 431, 435, P443, 444 and 446. The bulk of these changes look to be related to getting services out of King George Square, so for the most part I wouldn’t expect there to be too major a loss of patronage from these service changes to M2. Only the P426, 431, P443 and 446 duplicate the route of the M2 for any substantial distance, and they continue to do so between Herston and Roma Street.
