The cars that were originally paired with 6062 are now paired with car 6212, hence why 6214 was retired. The consist is set up like this: 6212-6063-6065-6064.
As for the Brooklyn shooting cars, I have no clue where that comes from. Are you referring to the 46's that were on the last year. If so, I think those cars are still in service (Someone can step in and correct me on this).
