Baldwin 60000 is an experimental steam locomotive built by the Baldwin Locomotive Works in Eddystone, Pennsylvania in 1926, during the height of the railroading industry. It received its number for being the 60,000th locomotive built by Baldwin.〔(【引用サイトリンク】url=http://www.aqpl43.dsl.pipex.com/MUSEUM/LOCOLOCO/USAhp/USAhp.htm )〕 It was designed to be the best locomotive that Baldwin ever made. It boasts three cylinders, weighed about , including tender, and can pull a load of up to . Its top speed is . 60000 was very innovative, carrying unusual technology, including a water-tube firebox. This was intended to improve efficiency but the tubes tended to burst inside the firebox. It is also a compound, expanding the steam once in the inside cylinder and then again in the two outside cylinders. Although compounding increased efficiency, it was an extra complication that the US railroads had mostly rejected by the middle twenties.〔 Also, the weight and length of the engine was too much for all but the heaviest and straightest track. This locomotive was experimental and was meant to be the model for future development. However, its demonstration runs never persuaded railroads to purchase more and in 1933, it was purchased by the Franklin Institute Science Museum for $1 and remains there today. == References == * * *(【引用サイトリンク】title=The Baldwin Locomotive Works Locomotive number 60,000 ) 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「Baldwin 60000」の詳細全文を読む スポンサード リンク
