The "eight vertical and eight horizontal" high-speed railway network is a high-speed railway network with the coastal, Beijing Shanghai and other "eight vertical" channels and the land bridge, riverside and other "eight horizontal" channels as the backbone, supplemented by intercity railways."Eight vertical and eight horizontal" can realize 1-4 hour traffic circle between adjacent large and medium-sized cities and 0.5-2 hour traffic circle within urban agglomeration.

The planning period is from 2016 to 2025, and the long-term outlook is 2030: by 2020, a number of major landmark projects will be completed and put into operation, and the scale of the railway network will reach 150000 kilometers, including 30000 kilometers of high-speed railway, covering more than 80% of large cities.By 2025, the scale of the railway network will reach about 175000 kilometers, including about 38000 kilometers of high-speed railway. The network coverage will be further expanded, the structure of the railway network will be more optimized, and the backbone role will be more prominent, so that the railway will play a better role in ensuring economic and social development.It is expected that by 2030, internal and external interconnection will be basically realized, inter regional multi-channel will be unblocked, provincial capital high-speed railway will be connected, cities and prefectures will be quickly accessible, and counties will be basically covered.
The Planning is in the original“Four vertical and four horizontal”On the basis of the main framework, add high-speed railway with passenger flow support, appropriate standards and development needs, and make full use of the existing railway to form a high-speed railway network with "eight vertical and eight horizontal" main channels as the framework, regional connection lines as the link, and intercity railways as the supplement.The Plan clearly defines the construction standards of high-speed railway network: in principle, the new projects planned for the main channel of high-speed railway shall adopt the standard of 250 km/h or above (which can be appropriately reduced in areas with complex topography, geology and climate conditions), and the railway with dense population, developed economy and large cities along the line can adopt the standard of 350 km/h.In principle, the regional railway connection line adopts the standard of 250 km/h and below.In principle, the intercity railway adopts the standard of 200km/h and below.
Specific planning scheme: First, build the main channel of "eight vertical and eight horizontal" high-speed railway.Second, expand regional railway connections.On the basis of the "eight vertical and eight horizontal" main channels, the regional connection lines of high-speed railway are planned to further improve the road network and expand the coverage of high-speed railway.Third, develop intercity passenger railway.While giving priority to the use of high-speed railway and ordinary speed railway to operate intercity trains to serve intercity functions, it is necessary to plan and construct intercity passenger railway of urban agglomeration that supports and leads the development of new urbanization, effectively connects large and medium-sized cities with central towns, and serves commuting functions.
After the implementation of the above road network scheme, the long-term railway network scale will reach about 200000 km, including about 45000 km of high-speed railway. The high-speed railway network will basically connect the provincial capital cities and other large and medium-sized cities with a population of more than 500000, realizing a 1-4 hour traffic circle between adjacent large and medium-sized cities, and a 0.5-2 hour traffic circle within the urban agglomeration.[1]
