Metroliner Service train led by coach No. 825, 1970s.

The Metroliners were high-speed Budd electric cars designed for use on the Pennsylvania Railroad's busy mainline between New York and Washington. The cars generally operated as married pairs, meaning that trains had an even number of cars. Luxurious interiors and fast running times made the Metroliners a viable competitor to regional airlines. Under Amtrak, Metroliner Service frequencies increased to keep up with demand, and trains often reached speeds of up to 110 mph. In the late 1970s, Amtrak refurbished and reconfigured part of the Metroliner fleet after it had run more than 1.5 million miles of service. Electrical components were moved from the underside of the floor to a new compartment on the roof. Notice that in this image, the roofs of the cars have been modified. Metroliner coach cars, such as No. 825 shown in this image, originally featured 76 seats. When Amtrak refurbished the fleet starting in 1979, the seating was reduced to 72.
