CRH2E-NG

CRH2E-NG EMU Train was born in Jult 2015, belongs to the CRH2-NG series, 8M8T in marshalling, the hole length is 401.4 m, has a maximum design speed of 250 km/h, and 275 km/h in the experiment

新型CRH2E-2462动车组,采用大量的新材料和新技术,采用全新的外观设计,给旅客提供更加舒适的旅行环境,相对于2461,2462取消了耐高寒抗风沙设计,其他设计与2641基本相同,可以满足中原以及南方广大区域的使用需求。CRH2E-2462于2017年短暂配属郑州局后,2018年转配属广州局。

Existing problems and deficiencies

CRH2-NG系列虽然对外观与内饰进行了大幅度更新,但并未对列车网络进行升级,使用的依然是源自CRH2的落后网络,不仅列车检修维护困难,还需要使用(日本进口的寿命约为5年的内置不可充电且无法更换电池的)有源NFC卡片写入包括列车车次数据、广播信息以及显示屏内容的列车运行数据,卡片寿命到期后需要更换,且部分列车因年代久远,相关车载装置也存在问题,另外该系统与列车网络深度绑定,通信协议落后,且使用光纤传输,更换系统较为困难,导致列车无法更换车次信息,部分列车只能长期固定交路,限制了列车运行范围。过分相时辅助变流器断电,空调、换气系统和空压机等会停止工作,重新启动时会发出额外的噪音。

备用制动也采用电制动(DC100V),当受电弓无法取电且蓄电池无电的情况下无法缓解制动,只能使用同型号同批次列车以固定方向救援(00车-01车),当使用不同型号动车组或机车救援时,只能全列手动缓解,限速5 km/h。

CRH2系列因牵引系统设计,过分相时部分其他电气设备断电,当重新启动时会发出额外的噪音,造成环境底噪波动,空调也会停机并重新启动,在夜间不利于睡眠。
