I think it's a good thing that the government is taking a more sustainable view towards it's High Speed Rail ambitions. It was more than a little disconcerting, the gung-ho style of building everything in such a massive rush with seemingly little worries about potential issues. I think, after taking a step back and looking at the situation, the construction will continue, but in a way that leave more people benefitting than before.

The key problem here is that the project does not even have a proper environmental inspection, it had approval for its old plan but that does not cover the revised plan. whoever changed the construction location (Luanhe Station) and failed to submit a new environmental inspection is the one to blame. The project representative claims that the new station location is better in terms of environmental protection as there will be less noise pollution to nearby residents etc., but change without permit is an obvious violation of the law, and the project was sued by local residents because of this (for whatever reason they might have).

this is not the only case. Jiaoji (Qingdao-Ji'nan) railway conversion project would be put on hold if it doesn't meet the environmental requirement by May 31st. and it did not only happen to railway projects. Wuxi subway line 2 construction was halted because it didn't have proper environmental inspection.

^ apparently this line has been operating without a project acceptance report since 2009. it's the 4th or 5th time that the Ministry of Environmental Protection tried to halt the operation in April because the project failed to reduce noise pollution to the legal level etc. the timing is quite sensitive though, considering the change of MoR and government policies on railway construction.

There was a terrible accident on this line in 2008 causing 72 casualties, which would have got the ex-minister Liu Zhijun sacked then, and many believe that due to the role that railways played during the Sichuan earthquake, he only got administrative sanction.

Finally Nanjing got its proper dedicated HSR station, the current Nanjing station is way too crowded as of now. I like the fact that compare to the current station, the new one is only a few kilometers farther away from the city center (on opposite sides of the city, though).

the station is about 8.5 km away from the city center.

there is space reserved for two subway lines, but Jinan subway plan has not been approved by NDRC yet, so public transportation from/to the station has to rely on buses in the near future (including a BRT line). Jinan might be the only case that as a provincial capital its subway plan is still waiting for approval while another city (Qingdao) in the province has already got approval (in 2009) and started construction.

Beijing-Shanghai HSR, Cangzhou West Station

Cangzhou is about 20 minutes away from Tianjin and 40 minutes away from Beijing by Jinghu HSR.

I am kinda concerned about the construction quality due to the rush work at most new stations, unless the construction will continue even after the service starts in late June. The tracks and signaling systems are ready, but the station house and exterior square are still under intense construction.

速度与安全

  “确定任何目标速度的前提都是以安全为保障”

  也许,很多人难忘这样的记忆:每逢春节前夕,当归心似箭的思乡情愫与春运一票难求、车站停换转赶纠结在一起时,多么希望脚下的列车能飞起来。

  这个看似天方夜谭的梦想正在变成现实。

  2010年12月,“和谐号”CRH380A新一代高速动车组在京沪高铁枣庄至蚌埠段综合试验中创出486.1公里的时速,刷新世界铁路运营最高时速纪录,成为中国高铁引领世界的新坐标。

  486.1公里,相当于波音飞机起飞的速度。

  人们在惊叹中国高速铁路创造的奇迹时,对于安全的担心也接踵而至:速度越高是否意味着越不安全?

  “高铁建设,核心就是安全。安全和速度并不矛盾,它是以一整套高科技体系、质量和管理作保障的。”轨道交通控制与安全国家重点实验室首席教授贾利民说。

  万钢打了一个比方:如果按照“速度越高就越危险,速度越低就安全”的逻辑,那飞机就是最不安全的,自行车就是最安全的。但根据世界交通事故的统计,结论恰恰相反。

  飞机之所以能在天上安全飞行,事故率低,是依靠先进的飞行器、导航系统等一系列高科技手段来保障安全的。高铁也是同样的道理。

  高速铁路是多种高新技术的系统集成,融合了交流传动技术、复合制动技术、高速转向架技术、高强轻型材料与结构技术、减阻降噪技术、密封技术、现代控制与诊断技术等一系列当代最新科技成果。

  高速铁路由于在全封闭环境中自动化运行,又有一系列完善的安全保障系统,所以其安全程度是任何交通工具无法比拟的。高速铁路问世35年以来,日、德、法三国共运送了50亿人次旅客。除德国因在高速铁路上架行人桥发生一起事故外,至今未发生过人员伤亡的重大行车事故。这是各种现代交通运输方式所罕见的。

  贾利民教授详细地解释了高铁速度与安全的关系。

  高速铁路的安全保障是建立在科学合理的轮轨、弓网和流固耦和关系,速度设计则是基于这三大关系的顶层设计。

  比如,在轮轨关系中有一个非常重要的参数,脱轨系数。这个系数有一个极限值,只要列车运行速度不超过这个极限值,列车就是安全的。如果安全系数是0.8,其对应的速度是500km/h,列车只要在这个速度以下运行就是安全的。

  高铁的速度就是根据这三大关系的顶层设计、指标和要求来开展相关的所有设计。

  一句话,运行速度只要在三大关系的极限参数内,怎么跑都是安全的。

  4月25日,针对高速列车发展,科技部又按时启动了“十二五”科技支撑计划“智能高速列车”。将给现有的列车加载智能列车系统,届时,列车运行时每个零部件的信息都会通过网络传输到指挥中心,三大参数更可以时时监控,哪怕有细微异常,网络系统都会给予警示。

  此外,比起只有几米的汽车制动距离,高速列车的制动减速也是设计在人体能够承受的基础上,制动距离约有8000多米。

  2010年“和谐号”创造出486.1公里的最高运营时速时,其脱轨系数、轮重减载力、轮轴横向力最大值分别是0.13、0.6、16,而其标准值是要求小于0.8、0.8、48。

  这些在外人看来略显枯燥的参数表明,中国高铁安全性表现不仅可靠,而且十分优秀。“我们确定任何目标速度的前提都是以安全为保障。只要符合、达到设计规范,高铁的安全是没问题的。”贾利民说,安全是一个系统工程,设计350公里时速,不是说投入运营之后,再去检验安全;而是把安全贯穿于设计、施工、制造到运营等全过程。

  在京沪高铁的车头里,驾驶室视野开阔,司机前是一个个液晶显示器,实时显示高铁运行的各个指标,很多操作都是自动控制,早已不是以前“开火车”的概念。

  工程技术人员介绍说,在列车运行管理中,安全措施也是由科技手段保障的。比如,我国高铁采用了当今世界最先进的无线传输控制技术,即“中国高速铁路自动控制系统”。整个操控系统都在调度指挥中心,所有程序均由电脑控制。其中,信息系统能让司机获得前方32公里的路况信息,在时速高达350公里的线路上,如果前方列车突然减速,后边列车会通过先进的无线传输控制技术在几十公里外获得指令,并自动将速度减至与前方列车相同速度,使前后列车距离保持安全间距。

  其次是“每天开行检测列车制度”。高铁在开始每天的运营前,都会双向开出动检列车,由40多人组成的各类检测人员携带专业检测设备,对全线线路及通讯设施的各项参数进行严格的安全检查。新建成的高铁开始运行前,更是要进行5万公里的跑车试验,当车辆跑到近4000公里时,就要送到检修基地,接受类似显微镜装置的全面检测。

  在高速综合检测列车中,技术人员实时查看检测轮轨动力学检测系统、通信检测系统、信号检测系统等。“做检测车,就是把安全放在首位,这就是个流动的实验室,是高铁质量和安全的一面镜子。”万钢说。

  速度,是各种交通工具技术创新与发展的永恒话题。自工业革命推动世界高速运转以来,人类不断追寻新式交通工具,将天涯化作比邻。第一艘蒸汽机船、第一台蒸汽机车、第一辆汽车、第一架飞机先后问世,都在不断修改人类的时空坐标,时间在缩短,空间在扩张。

  “交通的科技进步就是靠速度来拉动,这是唯一的牵引指标。”贾利民说。

  轮轨时速究竟能跑多少公里?至今没有定论。

  1964年,日本建成世界上第一条高速铁路,尽管最高运营时速只有210公里,但这在当时已经是个很了不起的巨大科技成就。

  到本世纪初,日本、法国、德国等国家围绕速度提升开展了一系列技术创新与实践,高速列车最高运营时速已达300—320公里。法国人特制的专用试验列车在2007年更是创造了惊人的时速574.8公里的最高试验速度。

  如同对飞翔的渴望,人类对速度的渴望也是与生俱来,而速度极限的一次次突破又不断激发人类新的探索和跨越。

  资料显示,在列车速度的角逐中,许多国家从没有停止过追求的脚步。德国已宣布研发时速400公里高速列车,法国AGV时速定位在360公里,日本正在完善他们的FASTECH360,还有美国、俄罗斯、西班牙、意大利、韩国等国家跃跃欲试。

  而中国似乎对此有着更急切的渴望。

  随着改革开放而来的人口大流动,作为国脉的铁路如何承载?高速成为必然的选择。京沪铁路连通长三角、环渤海两大经济发达地区,堪称世界上最繁忙的铁路干线。高铁的建成,将形成4小时经济圈,京沪铁路平均运输密度为全国平均水平的4倍。

  “我国引领世界的先进技术并不多,高铁就是其一。高铁对更高速度的追求不能停止,核心技术的研究不能停止。”浙江大学方攸同教授说。

  “通过技术进步追求更高的速度,是交通的永恒主题。当然,一定的速度和一定的安全保障,需要付出一定成本,考虑乘客的负担能力,在确保安全的条件下,追求合理的经济速度,也是必要的。”一位专家表示。

  同济大学铁道与城市轨道交通研究院吴萌岭教授说:“速度肯定是交通科技标志性的指标。当我们处于领跑位置时,绝对不能停下脚步,否则又将重新追赶。”

  “安不安全关键在于安全标准设定的保障系统。”在本次考察京沪高速铁路的座谈会上,万钢多次表示,我们要严谨务实地讲安全。安全在于持续的创新,这需要研究院所在跟踪、考察和研究中,从千万个安全因素中找到不安全的因素,在于搞工程的科学态度,而与速度没有直接关系。

is this implying that the chinese 500km-train will try to break the French TGV 574.8km/h world record before the Shanghai-Beijing route open at the end of June??
