NK Yard, located just east of downtown Youngstown, was the Great Melting Pot for the city's railroads, where Baltimore & Ohio, New York Central (and subsidiary Pittsburgh & Lake Erie, both Penn Central by this time), Erie (Erie Lackawanna), and Pennsylvania (also Penn Central) exchanged a complex mix of cars. New York Central is at far left, followed by the Erie, Pennsylvania and Baltimore & Ohio. From the Edgewood Street bridge, looking southeast.
