CRH2J

China-EMU努力收录更准确的中国动车组参数，高速铁路/城际铁路/城市轨道交通数据，但本站不是中国铁路官网，也不是中国中车公司官网，也不是地铁官网。历经多年的发展，中国动车组列车已经拥有很完备的产品系列，那么动车组都有哪些型号呢？和谐号目前有CRH1、CRH2、CRH3、CRH5、CRH380A、CRH380B、CRH380C、CRH380D，复兴号目前有CR400AF智能、CR400BF智能、CR400AF、CR400BF、CR300AF、CR300BF、CR200J-A、CR200J-B、CR200J-C、CR200J-D、CR200JS-G，城际市域动车组有CRH6A、CRH6F，没有CRH6S，还有CJ2、CJ3、CJ5、CJ6等，同时还有NDJ3。地铁列车也是动车组哦。高铁和动车都有哪些区别？它们是完全不一样的。中国动车组,动车组参数,中国高铁,中国高速铁路,城际铁路,城市轨道交通,复兴号,和谐号,动车组技术,不是中国铁路官网,不是中国中车官网,CR400,CR300,CR200,CR450,CRH380,CRH,Cinova,China-EMU,ChinaEMU,高铁类型,高铁都有哪些型号,高铁都有那些型号,动车组都有哪些型号,中国都有哪些动车组,动车和高铁,中国动车组的动车组参数,中国动车组大全,中国动车组所有型号,中国动车组列表,中国动车组发展史,中国动车组发展历程,本页面是

CRH2J EMU Train was born in June 2015, belongs to the CRH2 series, 4M4T in marshalling, the hole length is 201.4 m, has a maximum design speed of 275 km/h, and 300 km/h in the experiment

2011年07月23日，7·23甬温线特别重大铁路事故中，由CRH2-139E担当的D301次列车（北京南—福州）追尾由CRH1-046B担当的D3115次列车（杭州—福州南）。

D301次的CRH2-139E动车组（后车）1车至4车脱轨坠落桥下，5车悬空；D3115次的CRH1-046B动车组（前车）13车至16车脱轨。事后，CRH2-139E的1车至5车报废，11车至16车后被中国铁路总公司改造为被综合检测列车（CRH2J-0205），其余车厢被拆解；CRH1B-046的13车至16车报废，1车至12车被中国铁路总公司改造为训练列车。

2015年07月，由7·23动车事故中的事故车CRH2-139E改造的CRH2J-0205高速综合检测列车下线。安装了ATP、信号参数、无线场强、弓网关系、轨道几何形态、动力学及加速度检测的设备和线路监视系统，主要负责时速250—350公里级的高速铁路的轨道几何状态、动力学、接触网、信号、ATP、无线通信、线路环境等的周期性检测和新建线路的全方位检测。
