The East Rail Line () is one of eleven railway lines of the Mass Transit Railway (MTR) system in Hong Kong.
 It used to be one of the three lines of the Kowloon–Canton Railway (KCR) network.
 It was known as the KCR British Section (九廣鐵路英段) from 1910 to 1996, and the KCR East Rail (九廣東鐵) from 1996 to 2007.
 The East Rail was the only railway line of the Kowloon-Canton Railway Corporation (KCRC) before the construction of "KCR West Rail" (now known as West Rail Line).
Canton Road Station (Trad.
 Chinese: 廣東道站) was a planned railway station on the Kowloon Southern Link of West Rail Line between East Tsim Sha Tsui Station and Austin Station, beneath the shopping mall, Harbour City in Tsim Sha Tsui, by replacing the existing underground car park.
 But it was never to be built because of the failed negotiations between the Kowloon-Canton Railway Corporation (KCRC), the former developer of the station, and The Wharf (Holdings) Limited, the owner of the Harbour City.

Tuen Mun South Extension is a proposed extension of the West Rail Line to the Tuen Mun South () station in the vicinities of Tuen Mun Ferry Pier.

 It is planned to run on viaduct, since if it were to continue underground the gradient would be too steep for the trains to run through.
