The EMU-320 is a South Korean high-speed electrical multiple unit train manufactured by Hyundai Rotem and operated by Korail.

History[]

After the development of HEMU-430X, Hyundai-Rotem and Korail signed an agreement in December 2016 for supplying high speed trains that are electric multiple units, the first of its kind in South Korea in commercial service (the HEMU-430X is also an electric multiple unit, but it is not for service and mass production). The order was for two variants: 2 eight-car EMU-320 units (with an operating speed of 320 km/h) and 19 six-car EMU-260 units, to be delivered around 2020–2021.[1][2][3]

In September 2016, Korail held a contest for the public to decide the design of the new models.[4][5] In 2017, a mockup of the chosen design was exhibited to the public to promote the sister train (EMU-260) and receive feedback.[6]

Design[]

Technology incorporated in these trains is dereived from the experimental HEMU-430X train previously tested by Korail. The EMU-320 will feature the same design as EMU-260 trains , however the formation will consists of eight cars as suppose to six cars.[4][5] Unlike KTX trains, the EMU-320 uses distributed traction with driving trailers at each end and six powered intermediate cars as opposed to traction heads configuration.[2][7]

The train can accelerate from 0 to 300 km/h (0 to 186 mph) in 230 seconds, in contrast to 316 seconds for the KTX-Sancheon.[8]

Interior[]

Unlike KTX trains, the seats on EMU-320 features more leg room, wider armrests, USB ports, wireless charging pads, and entertainment display similar to the inflight entertainment system found on aircraft.[2] In addition, every seat is aligned with a window.[2]
