Technical features
- Further improvement on collision and fire resistance as well as electromagnetic compatibility and other properties.
- Improved low-resistance shape.
- In order to solve the problem that the colouring paint between different materials of the car heads peeling off easily by thermal expansion, an extra washer widen several millimetres is installed between 2 sections, comparing with the original design, to separate the sections of those materials for respective colouring. This makes the trains have 2 rings set up in the front, which is 1 more than that of the original design.
- The optimization of the bogie design and improvement of the interior structure.
- High-strength air tightness: to further enhance the airtight performance, the fully sealed pressurization of differential pressure control mode is adopted. The pressure change does not exceed per second.
- Improved bogie.
- Noise control: Using a variety of new noise absorption materials and noise barrier technology, EMU speed of 350 km/h inside noise keep in 67–69 db level.
- The axle load still maintained at a level of, under vehicle weight gained by enhancing traction power, structural quality and noise reduction level.
- High-efficiency regenerative braking.
- Ergonomic passenger interface.
- Label text on car body is painted with :zh:港鐵字體|MTR typefaces, including MTR Song for Chinese characters and Myriad MM for alphanumeric characters.
