Zhujiang New Town Automated People Mover System (Chinese: 珠江新城旅客自动输送系统; pinyin: Zhūjiāng Xīnchéng Lǚkè Zìdòng Shūsòng Xìtǒng), or APM Line, is an automated people mover (APM) system mainly serving the Zhujiang New Town area in Guangzhou, the new CBD of the city. It is an underground and automatic operating system. In terms of construction cost per kilometre, it is the most expensive APM system in the world, yet it is the shortest and least used line in the Guangzhou Metro network. The whole line started operation before the Asian Games on 8 November 2010 with the exception of Haixinsha Station and Canton Tower Station. This was due to the two stations being located close to the opening and closing ceremony venue.
The entire track of the Zhujiang New Town APM, with a length of 3.49 km and all nine stations are laid underground, making it the first all underground city APM in the world. The shortest distance between two stations is 315 metres with an average of the entire line approximating 473 metres.
The system was designed to provide service from 6:00 am to 12:00 am every day, and may run extra hours on special occasions, such as weekends, holidays or major events. But currently due to the low demand, trains are operating from 7:00am to 11:00pm.
