It has also been suggested to improve parts of MTR that are running now. Airport Station on the Airport Express will have a new platform to serve passengers flying out of Hong Kong International Airport's Skyplaza. New subway links to the stations are also being made, and it has been proposed to lengthen the Tseung Kwan O Line with a branch line to Tseung Kwan O South, and the Kwun Tong Line as far as Whampoa Garden, also linking with the Sha Tin to Central Link expansion.
