Domestic tech to form core of subway expansion plans

Chinese-made hardware and software will be at the heart of Beijing's subway system as it looks to expand in the coming years.

The transport network is expected to almost double in length between now and 2020, from the 554 km of track it had at the end of last year to 999 km four years from now.

Currently, it carries 10 million passengers every day, accounting for about 48 percent of the capital's public transport users and making it the busiest subway system in the world.
