PRR doodlebug 4666 stands at the depot in Parkton, Md., just before departing on its morning run down the formerly double-track Northern Central line to Baltimore on June 4, 1959. The Parkton local trains ended a little over three weeks later, on June 27. PRR 4666 survives and is currently in service on the Allentown & Auburn tourist line, which runs on an ex-Reading branch.
