After the Guangdong Through Train and all other intercity passenger services were suspended in early 2020 amidst the coronavirus pandemic, the KTT trains were placed into storage. On 31 July 2024, the General Administration of Customs announced that in June 2024, the State Council had approved the closure of all four railway ports of the inter-city through trains, effective from the date of notice, citing that high-speed passenger trains have effectively met the travel needs of passengers between the mainland and Hong Kong.[5]

Although the locomotive has a top speed of 200 km/h (124 mph), KTT only runs at a maximum service speed of 140 km/h (87 mph) on the Hong Kong section of the Guangzhou - Kowloon Railway and at 160 km/h (99 mph)[2] on the Guangzhou - Shenzhen Railway. KTT now has ten compartments (eight first-class compartments and two executive-class compartments).
Since March 2018, all KTT coaches have undergone minor refurbishments. Refurbished trains feature reupholstered seats, new flooring, train automatic broadcast system devices and improved barrier-free facilities.
