KTT (Chinese: t=九廣通|s=九广通|order=ts)[4] is a train set used by the MTR Corporation Limited in Hong Kong on the Guangdong Through Train route. It is used on the Guangdong line (Hung Hom (Kowloon), Hong Kong - Changping - Guangzhou East) of the through train service.
The double-deck "KTT" trailers have bottom floors which are lower than ordinary cars serving on the same pair of tracks.
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. Despite border reopenings, there were no plans to resume intercity services.
In 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 2000NaN0, KTT only runs at a maximum service speed of 1400NaN0 on the Hong Kong section of the Guangzhou - Kowloon Railway and at 1600NaN0 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.
