近日有媒体关注报道了中车四方股份公司出口新加坡C151A地铁车辆，部分返厂维修事件。衷心感谢各界朋友对中车四方股份公司的关心与支持，也欢迎大家对公司的生产发展进行监督，你们的关注将促使我们进一步抓好产品质量，为客户提供更加优质的产品与服务。
鉴于各界朋友对此次事件的关心，特将有关情况说明如下：
一、C151A地铁车辆总体概况
2009年5月与2012年4月，川崎重工、中车四方股份公司、川崎新加坡子公司三方组成联合体，两次获得新加坡陆路交通管理局（简称“LTA”）C151A地铁车辆订单，总计35列地铁车辆。首列车于2011年1月交付用户，2014年9月C151A全部35列地铁车辆交付完毕。
二、返厂维修车辆基本情况
2013年6月，运营方在对C151A地铁车辆进行例行检查时，发现部分车辆的车体存在局部缺陷，共涉及26列。
经鉴定，该缺陷由部分批次铝合金型材的原材料质量问题导致；经系统分析，认为此缺陷不具有安全风险，车辆可继续安全运营。本着对用户及产品负责的态度，经与用户协商，中车四方股份公司主动提出对存在局部缺陷的车辆进行分批返厂维修。
三、车辆返厂维修进程
目前分批返厂修复工作正在进行中，前面修复完成的车辆已经返回新加坡并重新投入运营，目前运行状态良好，首列修复完成车辆已安全运营近30万公里。
四、后续措施
中车四方股份公司是一家百年老企，已经为全球20多个国家和地区提供了30000多辆轨道交通产品，运用质量得到广泛验证。2013年6月，此次事件发生后，我们深感痛心，采取了一系列措施确保事件能够得到圆满解决。一方面积极与业主进行沟通，提出处理此次事件的解决方案，并落实好各项措施；另一方面，针对这次事件，公司通过问题分析和纠正措施流程的有效运行，公司内部进行了全面梳理，对公司质量管理进行了深入剖析并提出了改进措施。以此为契机，我们将进一步细化供应商管理和原材料检验的要求，从研发、采购、制造、质量、售后服务等各个环节进一步加大质量管理水平，努力为客户提供质量更高、运营更安全、乘坐更舒适的轨道交通产品。
再次感谢社会各界人士对公司的关心与支持，也欢迎大家对公司进行监督，帮助我们更好地发展。

In response to the recent media’s interest in and coverage on the shipping back of the C151A metro trains exported to Singapore by CRRC Qingdao Sifang Co., Ltd. (hereinafter referred to as “CRRC Sifang”), CRRC Sifang hereby express sincere appreciations for the care and support of friends from all walks of the society. Supervision by the general public is more than welcomed, as CRRC Sifang will be motivated by such focus to exert more intensified and consistent efforts for better service and products to our valuable customers.
In light of the above mentioned concern, CRRC Sifang hereby make the following explanations:
1. Overview on C151A Metro Trains
Respectively in May 2009 and April 2012, the Consortium formed by Kawasaki Heavy Industry, CRRC Sifang and Kawasaki Heavy Industry Singapore was awarded the C151A order for 35 sets of metro trains in total by the Land Transport Authority of Singapore (hereinafter referred to as “LTA”). The first set of train was delivered to the customer in January 2011 and the delivery of the rest was finished by September 2014.
2. General Information on Trains Shipped Back
In June 2013, some local defects were detected on the carbody shells of 26 trains during a routine inspection to the C151A trains by the operator.
Such defects, after evaluation, were identified to have been caused by unqualified raw materials of the aluminum alloy profiles in certain batches. Systematic analysis shows that such defects bear no safety risk and will not impair train safe operation. However, based on the sense of accountability to our valuable customers and products, CRRC Sifang offered to send the trains with local defects back to the manufacturing facility for repair.
3. Progress of Manufacturer Repair
Steady progress is being made on the batch by batch shipping back and repair of the involving trains. Trains previously repaired have been re-put into service in Singapore, delivering sound operation performance. The first set of such repaired trains has been working safely for approximately 300,000 kilometers.
4. Next Steps
As an enterprise of over one-hundred-year history, CRRC Sifang has delivered over 30,000 rail transit vehicles to more than 20 countries and regions in the world, which has extensively verified CRRC Sifang’ strong product quality. After informed of this incident in June 2013, we felt deeply distressed and took a series of measures to address the problem. Through proactive discussions with the customer, we proposed solutions and guaranteed that all measures were well implemented. Additionally, we launched procures for problem analysis and correction measures, carried our internal reviews on quality assurance practices and drafted improvement approaches. As a lesson to learn, we will further refine the requirements of supplier management and raw material inspection, intensify quality management through the entire process of R&D, procurement, manufacture, quality control and after-sales service. CRRC Sifang is and will always be a strong champion of rail transit products better in quality, safer in operation and more comfortable in riding.
Thank you once again for your care and support to CRRC Sifang. We welcome your supervision on the company. And your engagement will help us forge a better CRRC Sifang.
