I can only speak about my trains in NYC: If the conductor honks twice it usually means that the train going through the station isn’t going to stop. Sometimes it’s because it went Express, sometimes it’s because it went Skip Stop, sometimes it’s because it was just told it had to make up some time for an earlier incident so is changing to a different line’s route than what’s on the side of the train. It happens. Just grin and bear it and wait for the next train to show up.

I promise you, another train is coming.

And if another train never stops at the station again, there are way bigger problems in the world to worry about.

If the train does stop at the station, the honk (in retrospect) meant some douchebag was hanging over the platform not listening to the fact that a big, ginormous train was about to turn them into a pancake with strawberry syrup.
