KTT (Chinese: 九廣通)^[10] is a train set used by the MTR Corporation Limited in Hong Kong on the Guangdong Through Train (KCRC) route. The KTT is not the only service from Hong Kong to Guangdong. Service is also provided by the mainland Chinese railway operators.^[11]

The double-deck "KTT" trailers have lower bottom floor than the ordinary cars serving on the same pair of tracks.

Route[]

KTT is used on the Guangdong line (Hung Hom (Kowloon), Hong Kong - Changping - Guangzhou East) of the through train service.

Between January to May 1998 the KTT cars provided service between Hung Hom and Lo Wu stations. After the whole route was electrified, the KTT serves non-stop between Hung Hom station and Guangzhou East railway station. 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)^[12] on the Guangzhou - Shenzhen Railway. 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. The refurbishment is excepted to finished at 2019.
