The idea of traveling at higher speed has always been alluring to people for its sense of glamour. Down to the present day, the only mean of transportation, which has made this phenomenon possible, have been airplane. However, it is not easy to neglect the significance of the tedium and time consumption associated with air travel. Most of the today's airports are relatively distant from city centers, which effectively defeats the very basic concept of the modern city: the idea of seamless and smooth direct access, in and inter dense urban fabrics and in a larger scale within the metropolitan areas. From this point of view, the concept of Hyperloop rises as a serious contender among other competing ideas in a sense that one can experience travel on the ground with the very same speed as of the airplane, and yet not to concern about all deficiencies associated with the experience of flight. From my point of view, the idea of Hyperloop, will affect the impression of the cities and introduce a new style of modern life. People using subways today for intra-urban transportation, will be able to use Hyperloop to access longer distances, which in turn would provide them with more chances to work, do business and recreate while maintaining their daily lives in their hometowns. HK-XL is the shaped upon idea of elevating an urban scale transportation hub up to a regional level, by means of generating a hyper-rapid regional link between the Pearl River Delta, the largest urban area in the world in both size and population, and two of the most vibrant metropolitan areas in East Asia: Shanghai and Tokyo. The project is located in the former Kai-Tak international airport and is designed as a building complex of a large-scale Hyperloop terminal comprising two sets of 14 platforms for domestic and international travelers and an office tower as a preliminary back-up structure. The whole complex can potentially open up to a 20 million-sqm mega structure at the back (proposed only as a scheme).
