But the best thing with the Q69 is to give the Q69 its own limited instead of having the Q100 be the limited stop service. I would set up a Q69 limited to be a slower limited than the Q100.
Also the X51 should not merge with the QM3. NYCT and MTA Bus routes cannot merge and the QM3 as is a fast route, it is a route that is hard to revise regardless of the area that it traverses. Merging it with the X51 would make the route slower, taking it off Northern in the Auburndale Bayside area would get NIMBY opposition (we tried to address a possible express bus service that serves the more residential parts of Auburndale and Bayside unlike the current QM3 which runs on Northern and we met NIMBY opposition that ultimately killed any chance of us doing it). The best thing that can be done with the QM3 is to throw an extra bus or two on the line to expand the span of service on the QM3 and to see what happens as the later two AM trips on the QM3 can get seated loads (sometimes the QM3 can get SRO or people opt not to take the bus because of lack of seats)
