On a late spring day, it's MTA railroad action on the Long Island Rail Road and MetroNorth Railroad.

The video begins midafternoon at Chappaqua on the MetroNorth Harlem Line, then goes back to early that morning on the LIRR West Hempstead Line at Lakeview station. Then it's a bounce to later that afternoon at Scarsdale on the Harlem Line (where the only 12car train on MetroNorth is recorded). Finally, dropping back to the noon hour that day on the LIRR, it's more EMU action on the Main Line at Pinelawn.
