CRH3A-A (Engineering samples)

CRH3A-A (Engineering samples) EMU Train was born in November 2018, belongs to the CRH3 series, 2M2T in marshalling, the hole length is 104.1 m, has a maximum design speed of 200 km/h, and 220 km/h in the experiment

该车基于CRH3A与CR300BF平台，保持CRH3A的外形基本不变，增加了独立的司机室门，乘客门加宽，更加适用于城际和市域铁路快速乘降的需求。

2018年11月，4辆编组时速200 km/h城际动车组在中车长客下线。该车早期涂装为蓝色装饰，后于2020年调整为CR300BF样车涂装。

2020年07月06日，抵达铁道科学院环形铁道进行试验，型号命名为CRH3A-A。

2021年03月21日，CRH3A-A前往广州进行试验。2021年03月31日，CRH3A-A在广珠城际铁路进行试验。
