Ma On Shan Line Platform Modification Works

To tie in with the future 8-car train operation configuration of "East West Corridor", modification works on the Ma On Shan Line (MOL) commenced since end 2012, which include:

- extension of station platforms and roofs;
- retrofitting of automatic platform gates;
- enhancement of electrical and mechanical facilities;
- retrofitting of noise enclosures at Tai Wai Station and viaduct near Fok On Garden; and
- extension of overrun viaducts at Wu Kai Sha Station



  • Extension of station platforms and roofs



  • Retrofitting of automatic platform gates



  • Enhancement of electrical and mechanical facilities



  • Retrofitting of noise enclosures at Tai Wai Station



  • Retrofitting of noise enclosures at viaduct near Fok On Garden



  • Extension of overrun viaducts at Wu Kai Sha Station


The modification works have been substantially completed and the extended roofs and platforms along the stations on the MOL have also been opened in November 2016, in order to facilitate the 8-car train test on the MOL.

4-car trains on the Ma On Shan Line to be increased to 8-car trains

The existing 4-car trains on the MOL will be replaced with 8-car trains gradually starting from 2017. Upon the completion of train conversion programme, the overall carrying capacity on the MOL will be doubled to make passengers journeys more convenient and comfortable.

Phase 1 (from November 2016 to early 2017)
Opening of extended platforms on the testing of the signalling system

Before the launch of 8-car train service in 2017, the 8-car trains are now undergoing a 3-month dynamic testing during overnight non-service hours. To facilitate the train test, the extended platforms for stations along the MOL were open in November 2016, while the waiting area at the platforms have been adjusted to align with the stopping position of 8-car trains. Platform assistants, station broadcasts and notices are deployed to guide passengers to the designated waiting area for boarding. Passengers may need to walk a bit farther on the platforms during the transition period. We would like to appeal for passengers’ understanding of this causes any inconvenience.

Phase 2 (Starting from early 2017)
Mixed Fleet Operation of 4-car trains and 8-car trains

During the period of 8-car trains to be operated alongside 4-car trains on the MOL, we will enhance our communication with the travelling public to make sure that they continue to enjoy smooth MTR journeys.

Please refer to the MTR website for details:http://www.mtr.com.hk/en/customer/main/mol_platform.html

Configuration of 8-car trains

The fleet of 15 4-car MOL trains will gradually be replaced by 8-car trains in starting from 2017. New trains are purchased and the existing trains are also being converted to form the train fleets of 8-car trains. This is a complicated process to “lengthen” the existing 4-car into 8-car trains, which can be compared to a surgery, involving the disconnection and reconnection of various systems. Upon the completion of train configuration, a series of testing is needed to be conducted as well. The train conversion process on the MOL takes around a year to complete. There will be one 8-car train to replace the existing 4-car trains every month, while all 8-car trains will be put into service by end 2017.

Automatic Platform Gates Retrofitting works

Under the SCL Project, nearly 2,300 Automatic Platform Gates (APGs) will be retrofitted on 53 platforms at 21 stations along the East Rail Line (EAL) and MOL.

APGs retrofitting along Ma On Shan Line


Progress Updates

(Last updated: November 2016)

The APG installation along the MOL is underway and the installation works were completed at Tai Wai Station in February 2016. Installation works are now on-going at other Stations. The whole MOL will be retrofitted with APGs in 2017.

To avoid interrupting normal passenger service and regular maintenance works, the construction team has only two overnight hours to work on. Time is extremely limited for installation as well as testing and commissioning to ensure a highly accurate gate operation. It is expected that one to two sets of gates can be retrofitted per day. The Corporation will remind passengers to alert to the gate operation through different means including deployment of additional station assistants.

Platform Modification Works of the East Rail Line Stations


Progress Updates

(Last updated: November 2016)

Some East Rail Line (EAL) stations are about 100 years old, the platform structure has to be strengthened to support the extra weight of the APGs, as well as the additional wind loads that the APGs must withstand. This requires the installation of steel bars and brackets at the platform. Moreover, the curvature at some existing platforms will be adjusted to narrow the gap between the train and the platform. As the platform gates will have to work along with the new train fleet and signalling system so as to ensure the stopping accuracy needed to align the train doors with the APGs for MTR to maintain a highly reliable train service. Therefore, the new signalling system and new trains will have to be in operation before any gates can be installed.

Since November 2013, the Corporation has started the platform modification works at EAL stations to pave the way for the installation of APGs under the Shatin to Central Link project.

To facilitate the on-track dynamic testing of new trains for the North South Corridor of the Shatin to Central Link, works have been carried out to adjust the platform edges in parallel with the platform modification works along EAL.

The Golden 2-hour Midnight Challenge

Work on an operating railway like these is always challenging. In order not to affect normal passenger service and to carry out regular maintenance works, we can only conduct the works for two hours overnight after the last passenger train of the day has departed.
