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.

It is the first driverless rail transit line in Shenzhen, a science and technology demonstration line of Shenzhen Metro. Phase 1 of Shenzhen Metro Line 20 is 8.43 km long and has 5 stations in total. As a municipal supporting project of Shenzhen World Exhibition & Convention Center, it helps to build a regional comprehensive transportation system and create a "multi-center, networked, clustered, and ecological" urban spatial structure in Shenzhen, and bring the speed of Shenzhen metro to a faster level in the new era.
