The Federal Express (later officially known as just the Federal) was an overnight named passenger train run by the Pennsylvania Railroad and the New York, New Haven and Hartford Railroad between Washington, DC's Union Station and Boston, Massachusetts's South Station from 1912 to 1971. Train numbers on both railroads were 172 northbound and 173 southbound. At different times, its route has taken it across the Hudson River via a car float between Port Morris and Jersey City (the ferry Maryland), the Poughkeepsie Bridge, and finally the Pennsylvania Tunnel and Terminal Railroad. The final routing was identical to today's high-speed Northeast Corridor.
