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 in India
In India, trains in the future with top speeds of 250–300 km/h, are envisaged to run on elevated corridors to isolate high-speed train tracks and thereby prevent trespassing by animals or people. The current conventional lines between Amritsar-New Delhi, and Ahmedabad-Mumbai runs through suburban and rural areas, which are flat and have no tunnels. The Ahmedabad-Mumbai line runs near the coast and therefore, has more bridges, and parts of it are in backwaters or forests. The 1987 RDSO/JICA feasibility study found the Mumbai-Ahmedabad line to be the most promising.
