Both the SP1900 and East West line C-trains in eight-car formations will run on the conjoined line, now known as the Tuen Ma line, resulting in the platforms of the Ma On Shan line being lengthened from 2014 to 2016 to accommodate the longer trains and automatic platform gates by Gilgen Door Systems (part of Nabtesco Corporation) retrofitted on all platforms from 2014 to 2017. The SelTrac IS signalling system will also be upgraded to SelTrac CBTC, which equips the extension. Stations The following is a list of the stations on the Ma On Shan line.
