Take a look at the new mass transit vehicle South Korea is developing.
A hyper-tube train currently in development in South Korea reached a record speed of more than 621mph during testing on Wednesday, hitting speeds normally only seen by airplanes.
The Korean Railroad Research Institute (KRRI) announced the major milestone on Wednesday, claiming the train may have gone as fast as 633mph. The hyper-tube system has been in development since 2017, and had previously managed a top speed of 443mph. For comparison, Japanese Shinkansen trains top out at a maximum operating speed of 200mph, with commercial aircraft cruising at speeds between 497mph and 621mph.
