The company began by modifying wood freight cars to add steel underframes. Later it manufactured its own line of all-steel rail cars. == Founding == Joseph S. Ralston and Anton Becker founded the Ralston Steel Car Company in 1905 by purchasing the plant of the Rarig Engineering Company on the east side of Columbus. Becker had just patented a drop-bottom gondola car which would allow the automatic unloading of coal and ballast cars (hopper cars). Prior to this invention, cars were unloaded by hand shoveling.〔"Ralston Made First Railroad Gondolas to Order." ''Columbus Citizen.'' May 25, 1949.〕 An example of a Ralston-built (drop gondola ) can be seen here. 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「Ralston Steel Car Company」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
