History

After the development of the prototype HEMU-430X train, Hyundai-Rotem and Korail signed an agreement in June 2016 to supply high-speed 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 original order was for 5 six-car units,[1] but a further order of 14 more six-car units was placed in December 2016; both orders were scheduled for delivery from 2020 to 2021.[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 train and receive feedback.[6] On November 4, 2019, the first set was delivered to Korail.[7][8]

In August 2020, Korail held a naming competition for the public to decide on the name of the new model, which at the time was known as the "EMU-260."[9] The model was officially renamed to the "KTX-Eum" (KTX-이음) in October 2020, after Korail filed patent trademark with the Korean Intellectual Property Office.[10]

On January 4, 2021, the train entered service on Jungang Line operating between electrified section of Cheongnyangni and Andong.[11]

Design

Technology incorporated in these trains is dereived from the experimental HEMU-430X train previously tested by Korail. The KTX-Eum will feature the same design as EMU-320 trains , however the formation will consists of six cars as opposed to eight cars.[4][5] Unlike KTX trains, the KTX-Eum uses distributed traction with driving trailers at each end and six powered intermediate cars as opposed to a traction heads configuration.[3][12]

Interior

Unlike KTX trains, the seats on KTX-Eum feature more leg room, wider armrests, USB ports, wireless charging pads, and entertainment displays similar to inflight entertainment systems found on aircraft.[3][6][12][7][8] In addition, every seat is aligned with the window.[3][6][12][7][8]
