KTT now has ten compartments (Eight first-class compartments and two executive-class compartments).
Since March 2018, all of the KTT coaches have begun the minor refurbishment. Refurbished train feature reupholstered seats, new flooring, added train automatic broadcast system device and improved barrier-free facilities.
