CRH1A-A

CRH1A-A EMU Train was born in January 2015, belongs to the CRH1(ZEFIRO250NG) series, 5M3T in marshalling, the hole length is 207.89 m, has a maximum design speed of 250 km/h, and 285 km/h in the experiment

CRH1A-A型电力动车组是青岛四方庞巴迪铁路运输设备有限公司（BST）基于ZEFIRO高速列车平台设计的新一代动车组，8节编组，统型设计，定员613人，采用铝合金鼓型车体，标准时速250 km/h，最高速度275 km/h。

发展历程

2012年09月，原铁道部向BST再次订购新一批动车组，共包含时速250 km/h动车组106组，其中前46列为CRH1A型动车组，另外60组进行了改款并进行统型化，即CRH1A-A（1169-1228）。

2015年01月，新一代CRH1A-1169、1170两列动车组在秦沈客运专线进行动力学试验。

2015年08月，新一代CRH1A-1169型动车组在沪昆高铁进行试验。

2016年02月01日，新一代CRH1A-1169型动车组正式在广珠城际铁路载客运行。

2016年11月18日，CRH1A-A正式投入海南环岛高速铁路运营，替代海南所有CRH1A列车。2017年01月20日，海南东环高铁速度由200 km/h恢复250 km/h。

招标信息

2015年07月15日招标时速250 km/h动车组列车，CRH1A-A中标其中14组（1234-1247）。

2016年11月10日招标时速250 km/h动车组列车，CRH1A-A中标其中8组（1248-1255）。

2017年01月18日招标时速250 km/h动车组列车（2017TDZC-1-250），CRH1A-A中标其中5组（1256-1260）。

技术特征

CRH1A-A采用更为流线型的头型设计，同时由原来CRH1A的不锈钢车体改为铝合金车体，改善了车体气密性，优化了转向架悬挂，提高了稳定性，列车牵引功率由5300 kW增加到5500 kW，最大运营速度250 km/h，最高速度 275 km/h，设计寿命延长至25年。

列车车体采用开放型管状设计，可以使内部可用空间最大化，在相同轴重下，为同类型动车组中最大车辆断面面积。

坐席版本

标准版为时速250 km/h统型布局，列车定员613人。1号车为一等座车，定员48人。4号车设有无障碍卫生间，5号车为二等座车和餐车合造车。

在海南运行的部分CRH1A-A的1、8车均为一等座车，其中CRH1A-1179~1184（不含1182）的1、8车为定员48人的一等座车，CRH1A-A-1182的1、8车为商务/一等座车；CRH1A-A-1209~1216的1、8车为定员44人的一等座车。

另外，CRH1A-A-1184加装了线路综合检测设备。
