of the Northern Link. In the first and second phases of the study, the planning team had to investigate and compare the traditional wheel-rail and maglev technologies. Operating and maintenance costs were greater with maglev than with wheel-rail technology, The construction period of the project was expected to be longer for maglev than the wheel-rail technology solutions. Maglev was not conducive to the existing rail network and compatibility. Also with current high-speed railway operating speeds of up to , the less than an hour goal was able to be achieved. Thus to reach the GZ–SZ–HK XRL's three goals, there was no need to adopt a relatively high cost and the technical difficulty of maglev technology. Thus, despite the advantages that high-speed maglev technology has, until August 2003, both sides tended to choose more mature high-speed wheel-rail plans. In other words, the "Regional Express" that was originally intended to have been conceived as a maglev train was cancelled. In March 2003, the Guangzhou Railway Group Corporation general manager, Wú Jùnguāng, at the National People's Congress, submitted a bill that called for the construction of a Guangzhou–Shenzhen–Hong Kong Express Rail Link Passenger Line as soon as possible. The Guangzhou–Shenzhen Railway utilization has exceeded 90% and was saturated. According to the existing passenger growth rate, to 2005, the Guangzhou East to Shenzhen route would require 96-151 train pairs daily, which will greatly exceed the capacity of the line. It is difficult to meet the transportation needs of the future with the new high-speed rail showing greater potential in the pipeline. On 7 January 2004, China's State Council considered the “long-term railway network plan”, deciding to build more than 12,000 kilometers of “four vertical and four horizontal” Passenger Lines, including Hong Kong in the planning. The Guangzhou–Shenzhen section of the Guangzhou–Shenzhen–Hong Kong Express Rail Link correspondingly accelerated planning until July 2004, decinding to adopt the “Panyu – Nansha – Shekou – Hong Kong” route. The station located in Guangzhou's Panyu district would also connect with the Wuhan–Guangzhou Passenger Line. Route The route starts with a connection to the Wuguang High-Speed Railway at Guangzhou South railway station in Shibi, southern Guangzhou (Canton). From there it travels south to the same district before tunnelling eastwards underneath the Pearl River to Humen in Dongguan. It then moves south through three stations within Shenzhen and then across into Hong Kong where it arrives at West Kowloon Terminus in
