services share the same trackage. As a result, signal failures can affect both services. The Lantau Link section of the line (consisting of the Tsing Ma Bridge, Ma Wan Viaduct, and Kap Shui Mun Bridge) only allows one train to pass through each direction at the same time, raising the minimum headway between trains to 2 minutes 15 seconds. As a result, some Tung Chung line trains terminate at Tsing Yi during peak hours, instead of travelling the entire line. The signalling system is not capable of giving priority to Airport Express trains; as a result, Tung Chung line trains stopping at Sunny Bay station frequently impede Airport Express trains, which do not serve the station. The power supply system restricts the number of trains running between Kowloon and Lai King stations. The system can accommodate a maximum of one Airport Express train and two Tung Chung trains travelling in both directions at one time. The minimum headway on this section of the line is 3 minutes 30 seconds.
