A Line canceled past Central Park

I was writing the 10 AM airline back to the airport, only for them to just stop the train at the Central Park station, announce this is now the final stop, and kick everyone off. I am now in a standing room only bus, shoulder to shoulder with tons of people that are saying this is a common occurrence.

What is the point of a mass transit system that cancels its trips multiple times a day? I am missing a work meeting because of this bullshit.

How are they not in massive trouble for not following through on their routes?
