High-speed rail in Switzerland
, 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
The fastest operating conventional trains are the Chinese CR400A and CR400B running on Beijing–Shanghai HSR, after China relaunched its 350 km/h class service on select services effective 21 September 2017. Since July 2011 till September 2017, in China, the maximum speed was officially , but a tolerance is accepted, and trains often reach . Before that, from August 2008 to July 2011, China Railway High-speed trains held the highest commercial operating speed record with on some lines such as the Wuhan–Guangzhou high-speed railway.
The speed of the service was reduced in 2011 due to high costs and safety concerns the top speeds in China were reduced to on 1 July 2011.
