主题：【原创】刻薄 1 孙海英和吕丽萍 -- 吴刚看你跳舞

那是她境界没到，人家挣得钱是这帮土财主们自愿送的，咱们平头老百姓站一边看热闹就是了。你丫不是有钱吗？上当就上了呗，反正钱对于你们来说就是纸，就是数字嘛。

您的出发点绝对是好的，是恨铁不成钢。任何一件事情（事故），我们都可以从正反两方面来看，而看问题的角度就决定了你的结论。高铁发展太快了，有没有冒进？肯定有。建设过程中有没有贪污？绝对有，而且不在少数。高铁发展是否有利于咱们国家的综合国力的提升，绝对有！无论是对于路轨建设，配套设施的完善，人员的培训，车辆制造技术的提高，生产工艺的提高，增加对现有路网使用的效率，部队的快速集结等等等等都有绝对的好处，我没有办法一一列明，但是以上都是我们不能否认的。这就是中国特色，中国国情，上三步退两步，咱还是往前走了一步不是？你所期望的完美状态是我们每一个人都盼望的理想境界，但是那不是现实。没有任何一个国家可以在如此短的时间之内建设并且运行如此大规模的高铁系统，我是说任何一个国家都没戏！咱们是第一个吃螃蟹的，会不会出事故？很遗憾的说，会。（可以参照国际民航业的发展史）事故出了，而且很严重！就必须调查！必须搞清楚直接原因，间接原因，杜绝以后再次发生类似的惨剧！实事求是，说起来容易，做起来难喔。媒体的监督是很有必要的，他们的角色非常重要！但在媒体迅速成长扩张的今天，很多新闻从业人员的素质也确实需要提高，我们不需要另一个世界新闻报，或苹果日报，或南方系......暂时想到这么多，不敢铺开，我思维比较跳跃，条理不通的地方还请多包涵。

The expected construction cost for the initial 20 miles is $1.4 billion, or $70 million per mile.[2] Metro estimates the train will cost the city $184 million to operate over the next five years with fares covering $44 million of the operation costs and tax subsidies covering the remaining costs.[3]

Trains operate on city streets in a "center reservation," similar to the Red Line of the METRO light rail system in Houston, the surface sections of the Green Line in Boston, and some surface sections of the Muni Metro in San Francisco. Some parts of the line, such as the bridge over Tempe Town Lake (near State Route 202), have no contact with other traffic. The vehicles used are rated for a maximum speed of 55 mph, and have complete the 20 mile route in 65 minutes, including station stops.[4] An equivalent section of the Red Line bus route that the rail line replaced was scheduled for 80 minutes, and was subject to traffic delays during rush hour.[5] The system is powered by an overhead catenary that supplies power at 750V (page 5)

[edit] History

Various plans preceded the current implementation of light rail. The Phoenix Street Railway provided streetcar service from 1887 to 1948. Historic vehicles may be seen at the Arizona Street Railway Museum, with Car #116 celebrating her 80th birthday on 25 December 2008, just days before the opening of modern rail service. In 1989, the ValTrans elevated rail proposal,[6] was turned down by voters in a referendum due to cost and feasibility concerns. Other subsequent initiatives during the 1990s failed over similar reasons.

Metro was created by the Transit 2000 Regional Transportation Plan (RTP), which involved a 0.5 per cent sales tax and was approved by voters in Phoenix in 2000. Transit 2000 aimed at improving the local bus service (considered unacceptably inadequate compared to other major US cities) and the formation of bus rapid transit and light rail, among other things, which was seen as a more affordable approach. It used the route placing and color designations from the 1989 plan.

In March 2008, cracks in the system's rails were discovered. The cause of the cracks was determined to be improper use of plasma cutting torches by contractors.[7] The affected track was repaired by May at a cost of $600,000 with still no word on which parties will be held financially responsible.[8] The last of the concrete and rail for the system was installed in the end of April, with CEO declaring the system to be on time and on budget.[9]

There are 28 stations on the initial twenty-mile starter segment. The line celebrated its grand opening December 27, 2008, with official ribbon-cutting ceremonies and community celebrations spread throughout Phoenix, Tempe, and Mesa. The event was produced by Arizona's Entertainment Solutions, Inc.[10] and was attended by thousands of local residents who waited as long as an hour or more to ride the vehicles.[11][12] The stations have been designed to complement their immediate surroundings.[13] Station platform areas are approximately 16 feet (4.9 m) wide by 300 feet (91 m) long.

As of early March 2010, with ridership far exceeding first-year projections, income was close to meeting Metro's stated goal of 25% farebox recovery. With sales tax and other revenue decreasing, Metro is contemplating a variety of service changes, including shorter hours and slightly longer headways, to close the budget gap.[1

is one of them. Even though they had done experiments for quite long time, the light trains did kill quite a couple of cars, which happened to stop in the track in the cross-sections.

我只看到文章里提到了2008年3月发现铁轨有裂纹，修理，然后12月轻轨投入运行。

开始试运行，12月份正式通车

The last of the concrete and rail for the system was installed in the end of April, with CEO declaring the system to be on time and on budget.

还有，试运行这个规矩应该是通行的，各个城市都一样，所以人家觉得根本没必要强调

就是过激了。况且和我原文的意思似乎没有什么太大的关系。

我原文也没有认为你过激。我只是在说看问题的方法。客观一点。你要是铁路系统的我就更不可能和你去争什么官员腐败的问题。

你的这个回复替我说话的成分太多，都已经设定好“我“的立场了。以至于都设定好了我关于拆迁问题的立场。我没有办法回答。只有你自己能批驳。

为了不陷入无谓的争论，我退出你这个帖子，不再表达相关观点。

现在整个系统的调查没有出来，不知道到底是什么地方出问题，很多人就能洋洋洒洒写这么多意见。现在的我们的问题就是调查太少，思考太少，意见太多。

中国的空闲/阻塞信号系统是70年代从法国引进的。后来在此系统上有大的改进，包括有很多防止人为失误导致严重后果的自动系统。但核心思想和国外的现有系统一样的，都没有很大的变化，因为事件证明这是一个健壮有效地系统。工程上的设计，一定是考虑到各种失效的情况了的，一定有防呆设计，这次具体为什么出问题，需要的具体调查而不是胡猜。

GPS是美国的系统，美国能随时加扰或者关闭民用信号，而且是单向的，另外需要无线系统在车辆，调度间传递数据。空闲/阻塞信号系统是自持的，不需要外界的干预就能工作。

所谓雷达，火车的制动距离最小需要2公里以上，这一段距离，轨道早就能够拐弯了。

不要那么简单嘲笑既有的解决方案，或者认为别人没考虑到，这个专业的专家，工程师工作了几十年，上百年，你想到的别人早就想到了，而一个系统工程系统的复杂程度是超乎你想象的

1.不需要调查结果出来也知道你推崇的信号系统没有起到它应有的作用。因为在同向车道上它只有一个作用，就是防追尾。哪怕是人为破坏，也说明这套系统在中国人的操控下不可信赖。

2.我不具备铁道部总工的资质，提出可笑的设想也没什么。不过车-车通讯没有你想的那么可笑，出事的这两列车上要真配了GPS+短波电台+一些自动控制设备，这几十条人命也就救下来了，高铁也赢得一些宝贵的时间。当然你要有别的辙也行。反正一层避孕套没把握就戴两层，两层没把握戴三层，实在是没把握的话，别上路，这是聪明人的做法。贪功冒进，把肚子搞大了，骂他一句“愚昧”，还有错啦？

3.

你不觉得同样的逻辑，等调查结果出来，真发现我有什么地方说的不对，再出来批评更符合你做人的标准吗？

基本上中国历史几千年吃人史的潜意识就是这个

冒进的上路。

先是空车测试, 然后是逐段载人测试。很多人的第一次坐轻轨都是在免费的测试阶段. 即使这样还是撞翻了二十几两小车，杀了不少人。
