公里，是西藏首条电气化铁路。全线 16 次跨越雅鲁藏布江，地质条件复杂，桥隧比高达 75%，但这没有影响施工进度和整体工期。2020 年 4 月，全线 47 座隧道全部贯通；2020 年 6 月，藏木雅鲁藏布江双线特大桥主梁顺利合龙，标志着全线 120 座桥 梁主体结构均已完成。全线计划于 2021 年 6 月 30 日建成通车。拉林铁路的开通会发挥铁路沿线的集聚效应和辐射效应，形成新的区域经济增长点。Lhasa-Nyingchi Railway is a key project in Chinas 13th Five-Year Plan,with alength of 435 kilometers and a design speed of 160 kilometers per hour.It is the firstelectrified railway in Tibet.The Yarlung Zangbo River has been crossed 16 times.Thegeological conditions are complex and the ratio of bridge to tunnel is as high as 75%,but this has not affected the construction progress and the overall construction period.By April 2020,all 47 tunnels will be completed;In June 2020,the main girder of theYarlung Zangbo River bridge in Zangmu was successfully closed,marking thecompletion of the main structure of all 120 Bridges.The whole line is scheduled to becompleted and open to traffic on June 30,2021.The opening of Lhasa-NyingchiRailway will bring into play the agglomeration effect and radiation effect along therailway and form a new regional economic growth point.7.1-2 中国第一条电气化铁路中国第一条电气化铁路宝成铁路宝成铁路 Chinas first electrified railway-Baocheng railway宝成铁路（Baoji-Chengdu Railway）位于陕西省、甘肃省和四川省境内，北起陕西省宝鸡市，向南穿越秦岭到达四川省成都市，全长 668.198km，国家级客货干线铁路，是中国第一条电气化铁路。1952 年 7 月动工修建，1956 年 7 月建成通车。1958 年 6 月开始进行电气化改造，1975年在中国全国铁路中首先实现电气化。宝成铁路是一条连接中国西北地区和西南地区的交通动脉，也是新中国第一条工程艰巨的铁路。这条铁路的建成，改变了“蜀道难”的局面，为发展西南地区经济建设创造了重要条件。Baoji-Chengdu Railway is located in Shaanxi,Gansu and Sichuan provinces.Itstarts from

reduce load of trains由中国中车株洲所研制的新型列车供电系统近日在沈阳铁路局 AC380V 客运机车上正式运营。这是我国首次在该型机车上采用新的列车供电系统，改变了我国大多数旅客列车传统的柴油专车供电方式，增加车厢容量。目前，我国有超过 4 万节的普通旅客列车，供电设备体积大，线路复杂，既占车厢面积，又损耗大量能量。如果该技术能在所有在线运营的铁路客车上推广应用，既减少石油消耗，提高能源的环保性和使用效率，也提高我国现有列车的载客量和经济性。A new train power supply system developed by CRRC Zhuzhou Research Intitutehas been put into operation on AC380V passenger locomotives of Shenyang RailwayBureau.This is the first time for China to use a new train power supply system on thistype of locomotive,which changed the traditional diesel power supply mode of mostof Chinas passenger trains and increased the capacity of the car.At present,there are more than 40,000 ordinary passenger trains in China.Thepower supply equipment is large with complex circuit,occupied compartment area anda lot of consumed energy.If the technology can be applied to all railway passengercars presently operating,it will not only reduce oil consumption,improve energyconservation and efficiency,but also improve the passenger capacity and economy ofChinas existing trains.7.4-1 国外地铁事故催生武汉地铁一项发明国外地铁事故催生武汉地铁一项发明Foreign subway accidents gave birth to an invention of Wuhan subway轨道交通概论（中英双语）供电那些事儿6Introduction to Rail Transportation(Chinese-English edition)Stories&Cases2011 年 12 月 15 日，新加坡地铁南北线发生故障，检查发现部分列车的受电靴损坏或脱落，供电轨有 21 个抓钩脱落，原因不明。武汉地铁也采用第三轨供电模式。机电部供电车间工程师孙宏杰从该事故获启发，组建团队发明“接触轨抢修底座”。3 个月里，完成为轨道交通 1 号线定做的首套“接触轨抢修底座”。1 年里完成各项测试。如今，“三轨故障更换接触轨抢修底座”成为每隔三个月的必练科目。当武汉地铁三轨出现故障时，最短 2 个小时就能再建一条“三轨”，恢复正常运营。On December 15,2011,a malfunction occurred on the Singapore Metro North-south Line.The electric shoes on some trains were found damaged or fell off,and 21claw hooks on the power supply rail fell off,for unknown reasons.Wuhan Metro alsoapplies the third rail power supply mode.Sun Hongjie,an engineer at the powersupply workshop of the Electromechanical Department,was inspired by the accidentand organized a team to invent the contact rail repair base.Within 3 months,the first set of contact track emergency repair base customizedfor railway line 1 was completed.All tests were finished within 1 year.Now,Thirdrail fault replacement contact rail repair base has become a required practice everythree months.When the third rail in Wuhan breaks down,another third rail can bebuilt in two hours to resume normal operation.7.4-2 新技术弥补北京地铁旧有遗憾新技术弥补北京地铁旧有遗憾New technology makes up for old Beijing subway regrets在你乘坐北京地铁线路时，会发现线路轨道旁有接触轨（第三轨），可为地铁列车提供 750 伏电压，列车则通过受电靴与第三轨接触获得电力。北京首条采用接触网供电的地铁线路，6 号线通过隧道顶端的高压接触电网和车顶上翘起的“小辫”受电弓取电。从第三轨“脚下受电”到接触网“头顶供电”，输送电压的提高，带来了 6 号线其他性能的提升。现在全世界 70%以上的地铁都采用接触网供电，我国一些大城市如上海、南京、广州、等修建地铁也都采用了这种供电方式。When you take subway in Beijing,you will find there is a contact rail(third rail)next to the track,which can provide 750 volts to the subway train.The train getspower by contacting the third rail with the electric shoe.The first metro line in Beijingto be powered by OCS(catenary),Line 6 is powered by a high-voltage overheadcontact system at the top of the tunnel and a pantograph,a braid raised above theroof.From the underfoot power of the third rail to the overhead power of OCS,theincrease of transmission voltage brings about the improvement of other performanceof line 6.At present,more than 70%of the worlds subways are powered by OCS(catenary),and some big cities in China,such as Shanghai,Nanjing,Guangzhou,etc.,have also adopted this kind of power supply.
