FAQs about ITX
What is the ITX train?
The ITX (Intercity Train Express) train is a class of high-speed trains operating in South Korea that provide efficient transportation between major cities and regions outside the more heavily urbanized zones served by the KTX (Korea Train eXpress) system. ITX services include the ITX-Cheongchun and ITX-Saemaeul. The ITX-Cheongchun operates on the Gyeongchun Line, connecting Seoul to Chuncheon, while the ITX-Saemaeul, which replaced older Saemaeul trains, serves longer routes with fewer stops compared to conventional services. These trains are designed to offer a comfortable and quicker alternative to traditional train services, featuring amenities like spacious seating and modern interiors.What is the difference between ITX and KTX trains?
The ITX (Intercity Train Express) and KTX (Korea Train eXpress) trains are both integral parts of South Korea's rail network but cater to different aspects of travel needs. The KTX is South Korea's flagship high-speed service, primarily focusing on connecting major metropolitan areas across the country with speeds up to 305 km/h, offering fast travel times. In contrast, ITX trains serve as a semi-high-speed option, designed to connect smaller cities and regions not covered by the KTX. ITX trains typically operate at lower speeds than KTX, have more stops, and focus on comfort over sheer speed, making them more suitable for intermediate distances.How fast is the ITX train?
The ITX train's speed varies depending on the specific service. For instance, the ITX-Cheongchun can reach speeds of up to 180 km/h, which allows it to complete the journey from Yongsan in Seoul to Chuncheon in roughly one hour and twenty minutes. This makes it significantly faster than conventional trains on the same route but slower than the KTX trains. The ITX-Saemaeul, which serves other routes, also operates at similar maximum speeds. These speeds are adequate to reduce travel times significantly compared to older models of trains while providing an efficient service for those not served by the high-speed KTX lines.
