国际在线消息(记者张鸥 通讯员何经伟、吴可超):日前,新型CRH3A动车组在中车唐山公司下线,这是我国目前最先进的时速250公里等级动车组,是中国中车全系列、谱系化动车组产品家族的最新成员,具有安全可靠、智能化高、易于维护、节能环保、经济适用等特点。新型CRH3A动车组将在西(安)成(都)铁路客运专线载客运营,为快速公交化“互联互通”客运服务增添新动力。
新型CRH3A动车组是中车唐山公司以“绿色、智能、人文、一体化”理念自主研发设计的时速250公里动车组,采用4动4拖8辆编组,定员616人,是基于中国国情和运行条件下的“中国创造”。CRH3A动车组定位于干线铁路、城际铁路的快速公交化客运服务,能够满足经济圈、城市群之间的城际铁路快速“互联互通”,是目前国内唯一既适用时速200至250公里高铁客运专线,又适用时速160至250公里城际市域铁路的主力车型,可实现从干线铁路到市域交通的无缝衔接。
新型CRH3A动车组车头采用流线型设计,驾驶室两侧车窗位置的一抹“土豪金”,宛如京剧脸谱,在空气动学优化设计基础上显得动感十足。针对西成铁路客运专线等超大桥隧比运营环境,动车组采用全密闭车厢结构,不仅具有抗风、雨、雾等恶劣天气的能力,还大幅降低了列车运行时的车内噪音,消除了动车组穿越隧道时给旅客带来的耳膜不适感,乘坐更加安静、舒适。动车组不仅实现了核心部件和制造技术的完全自主化,还可根据用户需求进行个性化定制,给运用维护带来便利,具有明显的全生命周期成本优势。
国家发改委的材料显示,2020年我国城际铁路规划总里程达6222公里,目前已建成广珠、成灌、郑焦、郑开等800多公里城际线路。同时,国家还规划了京津冀、长三角、珠三角等21个城市群,覆盖全国人口稠密、经济发达地区。新型CRH3A动车组的问世恰逢其时,不仅进一步完善了我国轨道交通装备体系,更为推进区域交通一体化和新型城镇化建设,提供了快速安全、节能环保、经济适用的装备支持。
