The '''Ma On Shan&nbsp;line''' ({{zh|t=馬鞍山綫|first=t,j}}) was a [[commuter rail]] / [[rapid transit]] line that formed part of the [[MTR|Mass Transit Railway]] (MTR) system in [[Hong Kong]]. Coloured brown on the MTR map, the line acted as a [[branch line|branch]] of the [[East Rail line]] that connects the [[New towns of Hong Kong|new towns]] of [[Sha Tin]] and [[Ma On Shan (town)|Ma On Shan]] in the northeastern [[New Territories]].

The railway was one of three built by the [[Kowloon-Canton Railway Corporation]] (KCRC), which named it as '''Ma On Shan Rail''' ({{zh|t=馬鞍山鐵路|first=t,j}}, abbreviated as {{zh|t=馬鐵|labels=no|first=t,j}}). Since KCRC's merger of operations with the [[MTR Corporation]] on 2 December 2007, the line has been operated as part of the MTR network. Along with the [[West Rail line]], the line was integrated into [[Tuen Ma line]] Phase 1 on 14 February 2020 following the partial opening of the [[Sha Tin to Central Link]].

This is the only line without [[Platform screen doors|platform screen doors]] which is opposed to the [[West Rail line]], until the line was extended to [[Kai Tak station]] which had platform screen doors.

Since then, the usage of buses and taxis in the area decreased by as much as 50%. It was reported that some bus routes operated by KMB saw a decrease of ridership by one-third in just a few days.

Since the early planning stages, the Ma On Shan line was designed to be capable of joining with the [[West Rail line]]. Under Phase 1 the [[Sha Tin to Central Link]] project, the Ma On Shan line would be extended from [[Tai Wai station]] to [[Hung Hom station]] via [[East Kowloon]], with six new intermediate stations, including interchanges with the [[Kwun Tong line]] at [[Diamond Hill station|Diamond Hill]] and [[Ho Man Tin station|Ho Man Tin]], an additional interchange with the East Rail line at Hung Hom, and a new station, [[Hin Keng station|Hin Keng]], serving Sha Tin. The extension will connect to the West Rail line at Hung Hom and continue on to [[Tuen Mun station]] in the northwest New Territories via the current West Rail line and its [[Kowloon Southern Link|2009 extension to Hung Hom]]). Due to various delays, the new line opened only as far as [[Kai Tak station|Kai Tak]] on 14 February 2020, with the remaining section to Hung Hom to begin service on 27 June 2021.<ref name="TMLPhase1Opening">{{cite news |title=New rail line to open |url=https://www.news.gov.hk/eng/2019/07/20190718/20190718_175608_397.html |access-date=5 January 2020 |work=Government of Hong Kong News |date=18 July 2019}}</ref>

After the opening of the Tuen Ma line Phase 1 on 14 February 2020, the Ma On Shan line became part of the new line with three new stations in [[Hin Keng station|Hin Keng]], [[Diamond Hill station|Diamond Hill]] and [[Kai Tak station|Kai Tak]]. While technically still in operation, the name "Ma On Shan line" is no longer in use.

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<ref name="mtr8car">{{cite web|title=Ma On Shan Line: 4-car trains modified to 8-car trains|url=http://mtr.com.hk/en/customer/main/mol_platform.html|website=mtr.com.hk|publisher=[[MTR Corporation]]|access-date=15 January 2017}}</ref> and automatic platform gates by Gilgen Door Systems (part of [[Nabtesco|Nabtesco Corporation]]) retrofitted on all platforms from 2014 to 2017.<ref>{{cite web|title=First Pair of Automatic Platform Gates Installed on Ma On Shan Line|url=http://www.mtr-shatincentrallink.hk/pdf/en/multimedia-gallery/press/21112014_pr_e.pdf|website=Press releases|publisher=MTR Corporation|date=21 November 2014}}</ref> The SelTrac IS signalling system will also be upgraded to SelTrac [[Communications-based train control|CBTC]], which equips the extension.<ref name="TMLsignaltest">{{cite news |last1=Burroughs |first1=David |title=MTR to resume Tuen Ma Line CBTC testing |url=https://www.railjournal.com/passenger/metros/mtr-to-resume-tuen-ma-line-cbtc-testing/ |access-date=5 January 2020 |work=International Railway Journal |publisher=Simmons-Boardman Publishing, Inc. |date=10 June 2019}}</ref>
