Class E6 on the Pennsylvania Railroad was the final type of 4-4-2 "Atlantic" locomotive built by the railroad, and second only to the Milwaukee Road's streamlined class A in size, speed and power. Although quickly ceding top-flight trains to the larger K4s Pacifics, the E6 remained a popular locomotive on lesser services and some lasted to the end of steam on the PRR. One, #460, called the Lindbergh Engine, is preserved at the Railroad Museum of Pennsylvania. It was moved indoors to begin preparations for restoration on March 17, 2010. On January 10, 2011, PRR #460 was moved to the museum's restoration shop for a two- to three-year project, estimated to cost $350,000. The engine is listed in the National Register of Historic Places. 〔"New life for old iron," January 11, 2011, Intelligencer Journal/New Era, Lancaster, PA 〕 == Design == The E6 was designed by the Pennsy's General Superintendent of Motive Power, Lines East, Alfred W. Gibbs, and his team. They produced an Atlantic of modern design, featuring a large and free-steaming boiler, outside Walschaert valve gear, piston valves on the cylinders, and a cast steel KW pattern trailing truck designed by the PRR's Chief Mechanical Engineer, William F. Kiesel, Jr. Modern features never present on the E6 design, and never retrofitted, included the mechanical stoker, power reverse and feedwater heater. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PRR E6」の詳細全文を読む スポンサード リンク
