Recently, the first metro train from Ningbo Rail Transit line 3 (No. 03032) with the door independently developed by CRRC entered the Baozhuang Railway Station of Ningbo Rail Transit Line 1 from the Ningbo CRRC Base. The driver of Ningbo Rail Transit took over the vehicle and drove it into the Shounan Metro Vehicle Base of Ningbo. It marks the formal delivery of the metro vehicle door developed independently by CRRC Ningbo Times Electric .
The metro vehicle door project was initiated in the latter half of 2015. The project team has overcome the difficulties of control, locking and door manufacturing technology. It has completed the assessment of replacement and application successively, and obtained the qualification of batch promotion and application. In January 2019, the prototype of passenger room side door and cab side door of Ningbo Rail Transit Line 3 successfully passed FAI evaluation by Ningbo Rail Transit Group, Zhuzhou Electric Locomotive Co., Ltd., Guangzhou supervisory company and Ningbo Metro company, formally qualified for batch delivery.
In April 2019, the delivery of two metro vehicles (No. 03032 & No. 03033) of Ningbo Metro Line 3, including cab door and passenger room side door, was completed, and the door debugging, vehicle door shower test and factory acceptance were completed simultaneously. Besides, No. 03032 metro vehicle was officially delivered to the owner of Ningbo Rail Transit on April 10.
The delivery of No. 03032 Metro door indicates that the Metro door independently developed by CRRC has the capacity of mass promotion and application. At the same time, CRRC Ningbo Times Electric has taken a solid step towards the goal of "professional door manufacturer".
