Are you referring to this one?
The IRT Broadway Local?
Not any more – they retired the 1/9 dual line thingy a month or two ago. It’s back to just the 1 train being the Broadway Local.
I’ll concur in thinking they were asking about the big red 9 “artwork” in Midtown.
ColonelDax is correct. That is indeed the ‘Oh you know, on 57th Street - the building with the big red number nine’ building.
Yup. Thanks. Now I know where I was!
