                          鋼軌和枕木必須長期承受火車的重量,而碎石頭的一個任務是承擔防止鐵軌下陷的緩沖工作。另外,火車高速通過鋼軌,會產生噪音和高熱,而碎石頭的另外兩個重要工作就是吸收噪音和吸熱。 [閱讀全文]

                          有的列車還沒有到站,就在“前不著村,后不著店”的區間里停下,或者在不該停的車站停了下來,每次停下的時間少則幾十秒多則十幾分鐘甚至幾十分鐘,這就叫做“臨時停車”。一般說來,臨時停車在單線區間容易發生,特別是在開行列車對數達到飽和的區間更容易發生。造成臨時停車有哪些主要原因呢? [閱讀全文]

                          什么是站界?[2016-11-24]

                          為了保證行車的安全和分清工作責任,車站和它的兩端所銜接的區間有明確的界限,通常稱之為“站界”。在單線的鐵路上,站界的范圍以兩端進站信號機柱的中心線為界。在雙線鐵路上,站界是按上下行正線分別確定的;一端以進站信號機柱中心線,另一端以站界標的中心線為界。 [閱讀全文]

                          兩交匯線路的交匯口都有警沖標,在線路上的機車車輛停放位置是不能超過兩警沖標之間的線路位置的,只有這樣當另一輛機車車輛駛入時,兩輛車剛好不能相碰,既不會碰到頭,也不會碰到尾,這樣機車車輛的停放才是安全的。 [閱讀全文]

                          好多人會問,中國的高鐵建在橋上的比例為什么會那么高?這樣會不會大大增加高鐵的建設成本?中國高速鐵路橋梁比例高,有多方面因素包括技術層面,也包括經濟層面,但歸根結底是技術標準問題,目的就是為了高速列車的平穩高速運行提供保障。 [閱讀全文]

                          相信很多人都會有這樣的疑問,飛機上有安全帶,汽車上有安全帶,為什么時速超過300公里的高速動車組上沒有安全帶? [閱讀全文]

                          經常坐高鐵的人都知道,高鐵在凌晨0點到6點之間是沒有班次的,業內稱之為“天窗”。當然,我這里主要是指新建的高鐵線路,在老線上面還有一些動車組臥鋪(南車的CRH1E、CRH2E等車型)會在夜間運行。在許多人眼中的這種浪費,為什么會存在呢? [閱讀全文]

                          很多人都有一個疑問,為什么國外的高鐵站多數都建在市中心,而中國的高鐵站很多都建在偏遠的市區,換乘起來非常不方便,影響了高鐵客流的增長。 [閱讀全文]

                          還是不停地有人問,高鐵與動車有什么區別?包括現在非常火的在居庸關拍攝的美得令人震驚的花海里的和諧長城號,也有網友問,那不是內燃的,怎么也是動車組?先大致回答,高鐵是一個系統,包括軌道系統、車輛系統、信號系統、供電系統、調度系統,動車組只是其中的一個系統。此外,動車組分內燃動車組(DMU)與電動車組(EMU),動車組也并不意味著一定是高速的,動車組也有120公里的,一直到380公里的,一般時速超過200公里的才稱為高速列車。 [閱讀全文]
