As part of its bid for Sha Tin to Central Link (SCL) in the early 2000s, the MTR Corporation proposed an extension of the Kwun Tong line to serve the Whampoa Garden area, with an interchange at Ho Man Tin to an extended Ma On Shan line, which would provide an alternate route to the Tsuen Wan line across Victoria Harbour to Central South station. Its competitor, the Kowloon-Canton Railway Corporation, suggested constructing an Automated People Mover between Hung Hom and Whampoa instead.
