I traveled to Brewster, NY on Metro North's Harlem Line on my way to New York City on a warm and cloudy June afternoon. Metro North train 633 arrives from Grand Central Terminal stops and departs to Southeast. Train 664 arrives on the way to New York on track 1 due to track construction north of the station. Then a thunderstorm moves through with vivid lightning, loud thunder and drenching rain. Train 343 splashes through and stops on the way to Southeast. Train 666 arrives again on track 1. The rain lightens up and train 668 arrives on track 2 to Grand Central Terminal. Finally train 637 pulls into Brewster and departs toward Southeast.
