The first train for Shenzhen Metro Line 14 developed by CRRC Changchun Railway Vehicles Co was officially delivered on Oct 29, according to local media reports.

Shenzhen Metro Line 14 runs north-south in eastern Shenzhen and is equipped with in-vehicle facilities such as horizontal seats and wireless charging, making it suitable for long-distance travel.

The metro train has an A-type aluminum alloy drum body, with eight carriages and a maximum operating speed of 120 kilometers per hour.

It also has a fully automatic driving option designed in accordance with the world's highest automation level – GOA4, which provides functions such as automatic wake-up calls, automatic departure calls, precise parking and automatic detections.

In order to ensure the safety of its fully automated driving system, the unit has adopted an ethernet control system. For the first time in China, it integrates five types of comprehensive detection systems – including bow network detections, tunnel detections, boundary detections, track inspections and running department detections – in order to monitor the real-time status of vehicles and provide a data foundation for intelligent vehicle maintenance.

The train applies high-security core control components, as well as obstacle detection, vehicle-assisted collision avoidance, end-wall collision avoidance, derailment detection and other safety assurance technologies, and its entire vehicle network security has reportedly been upgraded to the 2.0 level.

Meanwhile, the train has adopted a series of measures to improve the airtightness of the unit and ensure the comfort of passengers when the vehicle enters and exits tunnels.

At the same time, the train employs sound-absorption and noise-reduction materials on the floor and side walls and controls the overall air circulation to further reduce noise during operation.
