翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Zig zag (railway) ： ウィキペディア英語版 Zig zag (railway) A railway zig zag, also called a switchback, is a method of climbing steep gradients with minimal need for tunnels and heavy earthworks. For a short distance (corresponding to the middle leg of the letter "Z"), the direction of travel is reversed, before the original direction is resumed.〔Raymond 1912. "Switch-back development … necessitating the use of switches at these ends and the backing of the train up alternate stretches."〕 A location on railways constructed by using a zig-zag alignment at which trains have to reverse direction in order to continue is a reversing station. == Advantages == Zig zags tend to be cheaper to construct because the grades required are discontinuous. Civil engineers can generally find a series of shorter segments going back and forth up the side of a hill more easily and with less grading than they can a continuous grade which has to contend with the larger scale geography of the hills to be surmounted. 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「Zig zag (railway)」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.
