The initial KTX-I trainsets, also known as simply KTX or as TGV-K, are based on the TGV Réseau, but with several differences.
46 trains were built - the initial twelve in France by Alstom, the remainder in South Korea by Rotem.
 The 20-car electric multiple units consist of two traction heads, which are powered end cars without passenger compartments, and eighteen articulated passenger cars, of which the two extreme ones have one motorised bogie each.
A KTX-I was built to carry up to 935 passengers at a regular top speed of 300 km/h (186 mph), later increased to 305 km/h (190 mph).
