[00:00.00]China will again lay claim to operating the fastest bullet train service in the world.
[00:09.59]According to Chinese media, the Beijing to Shanghai train will once again be allowed to reach speeds up to 350 kilometers an hour.
[00:24.06]A deadly crash between two bullet trains in 2011 caused China to limit the speeds to 300 kilometers an hour.
[00:36.85]The South China Morning Post reported the change will cut travel time by one hour on the 1,300 kilometer trip between Beijing and Shanghai.
[00:53.03]The faster Beijing-Shanghai trains will begin September 21 and additional lines will also be launched, according to the newspaper.
[01:06.75]China already has several of the world’s fastest operating trains.
[01:13.84]The fastest is a non-bullet train - the Shanghai Maglev - that can reach speeds up to 430 kilometers an hour.
[01:26.67]The train is limited to carrying passengers from Shanghai’s center to the city's airport.
[01:35.54]The term maglev stands for magnetic levitation.
[01:40.61]In this system, train vehicles are kept off the ground and powered by magnets.
[01:49.43]High-speed bullet trains have wheels and run on a track.
[01:55.51]The second-fastest train in the world is the one running between Beijing and Shanghai, according to the website Railway Technology.
[02:09.88]China also has more high-speed rail lines than anywhere else in the world - covering about 19,000 total kilometers, according to the Associated Press.
[02:25.11]The fastest non-operating train in the world - undergoing testing in Japan - has reached a top speed of 603 kilometers per hour.
[02:37.43]It is a Japan Railway maglev train.
[02:42.31]In Europe, Germany, Italy and Spain all have trains that can travel more than 320 kilometers an hour.
[02:54.12]In the United States, the Amtrak Acela Express – which connects several eastern cities - is the country’s fastest train.
[03:07.26]It can travel at a top speed of 241 kilometers an hour.
[03:15.19]Last year, Amtrak received a $2.45 billion loan from the U.S. government to help develop new high-speed trains expected to launch in 2021.
[03:32.53]Amtrak says those trains are designed to travel up to 300 kilometers an hour, but will begin service at about 260 kilometers an hour.
[03:46.51]U.S. company Hyperloop One is continuing to test its own high-speed transport system.
[03:57.62]Hyperloop is being developed by businessman Elon Musk.
[04:01.42]He created and owns the aerospace company SpaceX, as well as electric carmaker Tesla.
[04:10.52]Hyperloop operates in a similar way to maglev trains, but uses vehicles called pods.
[04:18.97]An electromagnetic force causes the pods to “float” on air inside a series of steel tubes.
[04:27.41]The system forces air out of the tubes to reduce pressure and lower the resistance for the vehicles.
[04:36.55]Musk recently announced a Hyperloop pod had reached a top speed of 355 kilometers an hour during a new test.
[04:50.29]This beat the previous record of 324 kilometers an hour, reached by a student team from Germany during a Hyperloop competition in California.
[05:02.51]Musk has said he plans to keep developing the Hyperloop system, which he hopes will eventually greatly reduce travel times between major U.S. cities.
[05:17.61]He previously said Hyperloop would be designed to reach a top speed of about 1,200 kilometers an hour.
[05:28.61]To most experts, that goal seems out of reach in the near future.
[05:35.85]However, a Chinese aerospace company just announced plans to build a super high-speed train that it says could reach a speed of 4,000 kilometers an hour.
[05:51.15]An official at China Aerospace Science and Industry Corporation recently spoke about the project during a conference in China, the state-run China News Service reported.
[06:06.24]The official said the planned train would use maglev technology, combined with a Hyperloop-style tube system.
[06:16.30]He said a project team is currently working with dozens of researchers and companies to develop the world’s first “high-speed flying train.”
