如何评价中国南车和日本川崎合资公司出口新加坡的地铁出现严重质量问题? 第1页

那么多专业的人在做着各种貌似专业的分析,为什么不去看看新加坡交通局的官方声明呢?

我来大概翻译下新加坡交通局的声明:

The Land Transport Authority would like to address some of the issues related to the 26 North-South and East-West Lines (NSEWL) trains that have been the subject of recent media and online discussion.

交通局要澄清下最近媒体和网络上上传出的地铁问题。

  1. The Land Transport Authority awarded Contract 151A in 2009 to Kawasaki Heavy Industries and CSR Sifang to design, manufacture, and deliver 35 new trains for the NSEWL. The trains were progressively put into service from February 2011, following rigorous testing of their safety and reliability.

2009年订中日合资的35个新车,从2011年开始逐渐交付使用,并且经过严格的安全性和可靠性检测。

Battery and Draughtscreen Issues

  1. Prior to the commencement of passenger service, all new trains arriving in Singapore would be put through testing and commissioning. The same was done for the KHI-CSR Sifang trains. During such testing, there was an incident on one train where the cover of the train battery housing flew open due to a build-up of gases. The manufacturer took immediate action to replace its supplier and improved the design of the battery housing for all affected trains.

在投入使用之前所有车都要通过检测,在检测中我们发现了其中一个车的电池箱盖因为内部空气聚集而 flew open(这里措辞很有意思,我都不知道怎么翻译合适)的情况,制造商很快更换了电池箱的供应商。

4. Incidents of cracks of the draughtscreen on five trains were also discovered. These were found to be caused by errors during the installation process and unrelated to the hairline cracks found on the 26 trains’ car-bodies.

5.It is not unusual to detect some defects on new trains. We then take appropriate action to have them rectified by the manufacturer.

5个车上发现了座位旁边的挡风屏有破裂,是由安装不当造成的,在新车上发现问题也是很常见的事情,我们已经让制造商修复了这个问题。

(注意以上为投入运营前检测出来修复过的问题)

Hairline Cracks

  1. In July 2013, during a routine inspection of the trains, hairline cracks on the surface of the car-body bolster
  2. [2]

  3. were found. 22 of the 26 trains were in passenger service then. LTA immediately carried out further inspections. No cracks were found on other components of the trains. (Please see Appendix 1 and 2 for the location of the car-body bolster and an example of a hairline crack.)
  4. Laboratory tests showed that these hairline cracks were due to localised impurity in the aluminium car-body material that occurred during the manufacturing process. LTA engineers and its contractor assessed that the hairline cracks would not affect the operational safety of the trains. To confirm this, LTA further sought the opinion of an independent third-party assessor, TUV Rheinland, which concurred that the trains were safe to operate.

(答主注:这里是主要问题)2013年7月一次例行检查中我们发现车厢的支垫出现细微裂纹,26个车厢中有22个正在使用中。车厢支垫就是把车厢托在转向架上的一块铝合金板。(看下图)

实验检测发现出现裂纹的原因是铝合金板上有局部的不纯(localised impurity),这是生产过程失误导致的。(是材料问题,而且从而我一个外行角度来看,跟焊接没有任何关系,转向器本身也没有任何问题,别被一干高票答案骗了,

混合动力East210

你为何关掉评论呢? )

交通局专家认为这对车的安全运行不会有影响,为此我们还咨询了第三方独立评估方,证明确实不影响安全运行。

看图:黄色为铝合金板,那一堆方的的是转向器。铝合金板托着车体压在转向器上。


  1. Due to the nature of the defect, the most effective way of addressing it is to replace the entire car-body shell. As the trains were under warranty, we required the contractor to replace the entire car body shell. Hence, since July 2014, the affected trains have been progressively sent back to the factory for rectification works
    [3]
    . The costs of the shipping are borne by the contractor.

修复这个问题的最有效方式就是更换整个车厢(没有解释为什么更换整个车厢,可能这个铝合金板和车体不好拆开?或者新加坡人认为反正在保修期我就要全换,希望业内人士解答)。既然车还在保修期,我们要求制造方更换整个车厢,运费由制造方承担。

  1. To ensure that this unexpected occurrence did not affect our train deployment, LTA has been working closely with SMRT. The replacement of a train car body is time consuming and labour-intensive, with each car body replacement taking up to four months. Hence, to minimise the impact on our train operations in Singapore as well as the lack of facilities and space for repair works of this nature at our depots, only one train is sent back to the factory in China at any one time. We did not send all of the trains back at once as they were still fit and safe for service and we wanted to ensure sufficient train-availability for commuters.

更换每个车厢要4个月,因为我们交通需求,我们只能一次运一个到中国去维修,因为本身裂纹问题并不会影响安全运行(意思是其余出现裂纹问题的车厢还在使用中)。

  1. Starting next year, with the arrival of more new trains for NSEWL and when trains currently undergoing resignalling are ready, LTA will be able to send two trains concurrently for replacement works. This will speed up the rectification programme and its completion can be brought forward to 2019.

明年以后我们车数量充裕了,加上信号系统改善,我们将能每次送回2个车厢去更换,2019年将全部更换完毕。

  1. As of today, the car-body replacement for five of the 26 trains has been completed. The car-body of the sixth train is being replaced. As per safety protocols, LTA, together with the contractor, will continue to carry out rigorous inspections to ensure that all trains are safe for service.

到现在,5个车厢已经更换过,交通局和制造方会继续严格检车来确保安全。


好了,我们来看看这件事情的实质:

前面两个小问题(电池箱和挡风屏)都不是主要的,发现后很快就解决了,不再讨论。

铝合金板出现细微裂纹,是一个不会影响正常运行的的质量问题,否则新加坡也不会让那么多有这个问题车继续跑了这3年,还要继续跑3年,新加坡不是那种国家好吧,新加坡地铁的运量,去过新加坡的人都知道,新加坡的私家车可不是你想买就能买的,所以其地铁是最主要的交通方式。

但是既然还在保修期,新加坡要求更换也无厚非,更换过程将于2019完成。新加坡也不用承担包括运费在内的任何费用。

本来这是一个纯粹技术性的问题。而且是3年前的问题,是一个不会影响安全的的问题,而且是一个除非特意挖掘,除了工作人员不会知道的问题。

那么这个问题为什么突然被摆到公众面前,然后添油加醋炒起来以至于中新两国官方不得不回应呢?这就要问问香港媒体了。


——“若非《传真社》记者锲而不舍的追查……”这句话可能解释了一切。

质量问题不是没有,但是媒体怎么报道,是何居心也同样是问题。
