Hong Kong Shatin to Central Link (SCL) is the backbone of Hong Kong's rail transit system. It is formerly known as the Kowloon-Canton Railway, which has been in operation for nearly 100 years, and its engineering construction and technical design of SCL are extremely difficult. After the completion of the SCL, two traffic corridors will be opened - the East-West Corridor (East Rail Line from Wu Kai Sha to Tuen Mun) and the North-South Corridor (North South Line from Lo Wu to Admiralty). Fangda Innotech has set up an automatic retractable pedal in the project to realize synchronous linkage with PSD system, and an outdoor 3D laser gap passenger detection system has been provided to ensure the personal safety of passengers. On May 15, 2022, the cross-sea section of the Hong Kong East Rail Line was officially opened. Chief Executive of the Hong Kong Special Administrative Region, cut the ribbon on the cross-sea section. This line is the fourth cross-sea line in Hong Kong and has become an "important milestone" in the development of Hong Kong rail transit.

Beijing Subway Line 5 is a key supporting rail transit line for the 2008 Beijing Olympic Games, and also a north-south rail transit artery running through the city center in Beijing's transportation network. The total length of the line is 27.5 kilometers, with a total of 23 stations, including 16 underground stations, 1 ground station and 6 elevated stations. Since its opening in 2007, the PSD system of Fangda Innotech has provided citizens with professional and safe travel services for more than 10 consecutive years, helping to create a world-renowned international Olympic sports event.

Zhongda modified old lines in half-height safety doors of Taipei MRT, one of the busiest rail transit backbone lines in the city. Since its opening in 2011, Fangda Innotech PSD system has provided rail transit travel safety guarantee for Taipei citizens for more than 10 consecutive years.

It is the first general contracting project of PSD system undertaken by Fangda Innotech since its establishment. With a total length of 36.33 km and a north-south "Y" shape, the main line starts from Guangzhou East Railway Station, ends at Panyu Square in the south. The branch line starts from Tianhe Coach Terminal Station in the north, and merges with the main line at Tiyuxilu Station, with a total of 18 stations are all underground stations. It is a strategic transportation line for Guangzhou to transfer its urban development focus to southern part of the city. Since its opening in 2005, the PSD system of Fangda Innotech has been used safely and stably for more than 17 years.
