Featuring Metro North New Haven Line trains at Pelham and New Rochelle. Just west of Pelham and before crossing the Hudson River Parkway, the trains complete a power changeover at track speed, between under-running third rail and catenary wires.
New Rochelle is the first station, toward New Haven, where Amtrak and Metro North meet up. Most Northeast Regional trains (such as train #93 to Norfolk in this video) stop here with all Acelas as well as the Vermonter bypassing this station.
