Night Flying Over The Flyover. A train of Kawasaki-built MTA Metro-North Railroad M8s traveling on the New Haven Line crosses the Harlem Line on the Woodlawn Flyover in the Bronx, New York, on the night of April 2, 2025. The small handful of diesel-powered coach trains will all normally have the locomotive facing north, and there are no regular freight operations through here, so the electric MU M8 fleet makes up greater than 99% of the daily traffic over this track, so it can be difficult to come up with a 'creative capture' in this area.
