KTX II or KTX-Sancheon is high speed train built in South Korea by Hyundai Rotem in the second half of the 2000s and operated by Korail since March 2009. It can reach speeds of up to 352.4 km/hour (218 mph).
The Shinkansen, also known as the "Bullet Train", is a network of high-speed railway lines in Japan operated by four Japan Railways Group companies. The test run of the train can reach the speed of 443 km/h (275 mph).
Transrapid or TR-09 is a German high-speed monorail train using magnetic levitation and can hit a speed of 450 km/hour (281.1? mph).
As technology pushes train speeds to close to 400 kms per hour, safety and efficiency will be paramount.
