This was the standard light freight locomotive of the USRA types, and was of 4-8-2 wheel arrangement in the Whyte notation, or 2′D1′ in UIC classification. A total of 15 locomotives were built under the auspices of the USRA. None of the originals built under USRA auspices or any of the subsequent copies were preserved. ==References== * * * * *https://archive.org/stream/railwayage65newy#page/1066/mode/2up *https://archive.org/stream/railwayage65newy#page/1070/mode/2up *https://archive.org/stream/railwayage64newy#page/1040/mode/2up 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「USRA Heavy Mountain」の詳細全文を読む スポンサード リンク
