CRH3A型动车组,是由中车唐山机车车辆有限公司、中车长春轨道客车股份有限公司生产的一款时速250公里动车组。

发展历程

2016年07月14日,CRH3A新型动车组获得设计制造许可。

2016年10月,当时编号CRH3A-5218的新头型动车组从长客开赴环铁测试,从而曝光了获得准生证后进行量产的CRH3A的新造型,这个造型明显特点是司机窗附近的金色色块。

技术特征

该动车组电机悬挂方式、车轮车轴、构架、联系枕梁等结构借用CRH380BL的成熟结构,采用CW410(D)型转向架,采用YGZN2Q278牵引变流器。车体长度由24200加长至25000mm,高度保持3900mm不变。车辆定距、车端距离、顶车位与CR400标准动车组一致,网络拓扑结构、硬件配置均有所提升。在定员613人满载状态下,能保证动车组在20‰的坡道上静止和启动不溜车,实现坡停、坡启。

CRH3A型动车组进行了全方位人性化设计,采用了和“复兴号”动车组相同的旅客界面,先进的车厢顶部气幕式通风系统,使车内空调出风更均衡更自然。全新设计的舒适座椅和大空间过道,也给乘客带来了更佳的乘车体验。除此之外车内卫生设施也有了一定提升,全车配有坐式、蹲式各6个卫生间,在4号车厢还设置有方便残疾旅客的无障碍设施和无障碍卫生间。

招标信息

2016年底和2017年初,铁总两次招标购买时速250公里动车组,涉及CRH3A共59组。

其中2016年11月10日招标中,长客中标21组、唐车31组,2017年01月18日招标中,长客再次中标7组。

2017年年初,首列CRH3A编号改为5230。

运营范围及车次

2017年07月28日,首列长客产CRH3A新型动车组亮相成都。

2017年11月,唐车产CRH3A逐步交付西安铁路局。

2017年11月22日,CRH3A参与西成高铁全线模拟运行。

2017年12月06日,随着西成高铁开通运营,CRH3A正式载客运营。

2018年01月起,遵循集中配原则,CRH3A全部集中配属成都局集团成都东动车所,主要运营宁蓉、成贵、渝贵、贵广等线路及成都局集团城际线路。

后续在运行中部分列车放宽最大功率限制,以提高列车性能,和“技术提升型”CRH3A-5257策略相同。
