Jersey Arrow II cars still lettered for Penn Central have just exited the Hudson River Tubes minutes after departing Penn Station. 70 Arrow II cars were built by General Electric in 1974.
The three biggest passenger carriers - Pennsylvania, New York Central, and New Haven - merged to create the ill-fated Penn Central, whose passenger losses and poor service led to the formation of Amtrak and state-owned commuter lines.
Thanks largely to mergers and bankruptcies, New Jersey's commuter railroads underwent profound changes between the end of steam and the takeover by NJ Transit in 1983.
