The interchange between the Tsuen Wan Line and the Kwun Tong Line, the Island Line and the Tseung Kwan O Line, as well as that between the Kwun Tong Line and the Tseung Kwan O Line, are two stations long, allowing cross-platform interchange wherein a passenger leaves a train on one side of the platform and boards trains on the other side of the platform for another line. For example, when passengers are travelling on the Kwun Tong Line towards Tiu Keng Leng, getting off at Yau Tong would allow them to switch trains across the platform for the Tseung Kwan O Line towards North Point. Whereas, staying on the train and reaching Tiu Keng Leng would allow them to board the Tseung Kwan O Line trains towards Po Lam/LOHAS Park. This design makes interchanging more convenient and passengers do not have the need to change to different levels. However this interchange arrangement is not available for all transferring passengers at Kowloon Tong, Central, Hong Kong, Nam Cheong (Except transfer between Tuen Mun and Hong Kong bound trains), Mei Foo, Tai Wai Station (Except alighting from Ma On Shan Line to change southbound trains for East Rail Line) and Sunny Bay (Except alighting from Tung Chung bound trains to Disneyland Resort Line) stations, mainly because this service is available only when there are two continuous stations shared as interchange stations by two lines.
