M9s at Yonkers. Amtrak Lake Shore Limited (Train 49) on Sunday, February 14, 2021 (AMTK 715, P32AC-DM leading) passes through the station in Yonkers, New York shortly after beginning its journey from New York's Penn Station. Ten M9s built for MTA LIRR are visible outside the Kawaski factory in Yonkers, New York. The fulfillment of this order has been delayed by a variety of factors, but a number of M9s see daily service on the LIRR, allowing M3s to see their way to storage if not retirement.
