1. I feel like doing all of this would be pretty messy and confusing on many levels: riders perspectives, additional interlining etc. Altho I agree should continue to 6th Ave on weekends, whether to Forest Hills or 96 st. ( trains really needs that help on weekends in my experience lol)
2. Pretty sure this was discussed a lot in the 63rd st closure thread. As much as I think letting run to Forest hills on weekends can reduce the late night switcheroo confusion a little but idk.
3. I have some doubts about that, both and on 53rd, probably, but the is well known for many common issues, so itll need the help, even if riders doesn't take the on QBL local as much as other routes.
