High-speed rail in Europe
Switzerland has no high-speed trains of its own yet. French TGV (TGV Lyria) and German ICE lines extend into Switzerland, but given the dense rail traffic, short distances between Swiss cities (because of the country's small size) and the often difficult terrain, they do not attain speeds higher than 200 km/h (ICE3) or 160 km/h (TGV, ICE1, ICE2). The fastest Swiss trains are the ICN tilting trains, operated by the Swiss Federal Railways since May 2000. They can reach higher speeds than conventional trains on the curve-intensive Swiss network, however the top speed of 200 km/h can only be reached on high-speed lines. The former Cisalpino consortium owned by the Swiss Federal Railways and Trenitalia used Pendolino tilting trains on two of its international lines. These trains are now operated by the Swiss Federal Railways and Trenitalia.
High-speed rail
China has the largest network of high-speed railways in the world and in 2015 it encompassed of high-speed rail or 60% of the world's total. It is also the world's busiest with an annual ridership of over 1.44 billion in 2016. According to Railway Gazette, the trains between Shijiazhuang and Zhengzhou East have the fastest average operating speed in the world at . The improved mobility and inter connectivity created by these new high speed rail lines has generated a whole new high speed commuter market around some urban areas. Commutes via high speed rail to and from surrounding Hebei and Tianjin into Beijing have become increasingly common, likewise are between the cities surrounding Shanghai, Shenzhen and Guangzhou.
