MTR KTT

KTT 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 lower bottom floor than the 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 are currently no plans to resume intercity services.

Although the locomotive has a top speed of 200 km/h, KTT only runs at a maximum service speed of 140 km/h on the Hong Kong section of the Guangzhou - Kowloon Railway and at 160 km/h 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.
