KTX offers two classes: First Class and Standard Class. Tickets also specify whether a seat is forward-facing or backward-facing according to the direction of travel. First Class seats are arranged 2+1 across the train and Standard Class seats are configured 2+2. There are special reserved Family seats, which are grouped in four, including 2 forward-facing and 2 backward-facing seats. There are reserved seats and unassigned seats. KTX trains have no restaurant cars or bars, only seat service. From 2006, one car of selected KTX services functions as a moving cinema.
