I saw that thread you created, you're asking for potentially sensitive information, that's why the train operators/conductors didn't say anything. You're better off e-mailing NYC Transit about it.
You are really good, I'm impressed with the work. If you don't mind I'd like to see the following:
B68 Coney Island-Stillwell Avenue
B68 via Coney Island Avenue and Brighton Beach Avenue
and
B4 Bay Ridge Narrows Avenue
B4 via Neptune Avenue and Bay Ridge Avenue
