Spatial consistency of world widehigh-speed railways'' growth
High-speed railway network diffusion process worldwide in 1960-2010-ties, specially in China with geographically detailed approach is studied. The main spatial regularities of this spatial process are the same as traditional land transport networks (usual railways and roads): the sprawl of high-speed rail networks from dendrite forms to circuital forms; spatial complication of topological structure; the most simple networks are dominated, but complicated ones are quite rear. China has the most complicated spatial structure with more than 20 circuits.
