Carrying an average of 4.9 million passengers every weekday, the MTR is regarded as one of the world's leading railways for safety, reliability, customer service, and cost-efficiency. To perfect China's high-speed railway link network and enhance communication between Hong Kong and the Chinese mainland, Guangzhou-Shenzhen-Hong Kong XRL is a strategic railway project that must align with the Chinese Train Control System Level-3 (CTCS L3) (equal to European Train Control System Level-2 (ETCS L2) standards). This XRL consists of two sections: the Guangzhou-Shenzhen and Hong Kong sections. The 102 km Guangzhou-Shenzhen section opened on December 26, 2011. Trains on the Guangzhou-Shenzhen section will run at speeds as high as 350 km/h. The entire Guangzhou – Shenzhen – Hong Kong XRL is scheduled to open in 2015. Now, this XRL is the Pearl River Delta cross-boundary transport infrastructure.
Trains will run on the Hong Kong section at high speeds and must do so in a complex geographic environment. In view of the requirements, Guangzhou Railway and MTR were concerned about ensuring railway security, reliability, and efficiency. For the communications system, Guangzhou Railway and MTR were facing the following challenges:
The Guangzhou-Shenzhen section runs on a bridge across the Pearl River while the Hong Kong section connects Shenzhen and Hong Kong through tunnels. Both sections carry high-speed rail traffic and run through complex geographic environments, and demand wireless dispatch systems with 99.999% reliability along the entire network. Huawei offered a solution tailored to the customers' high network security and reliability requirements. Huawei's solution has the following key features:
The Guangzhou – Shenzhen – Hong Kong XRL project connects Pearl River Delta (PRD) 1-hour, and Beijing 10-hour economic and living circles, and reaches 16 cities of China's mainland. This project will promote Hong Kong up to HK$87 billion in economic development over the next 50 years and further consolidate Hong Kong's position as a regional center.
Additionally, this project brings new railway operation and technology innovation values to MTR and upgrades the reliability of wireless communications.:
