Related Works On East Rail Line and Ma On Shan Line

Platform strengthening works are being carried out now at the East Rail Line Stations, while platform and roof extension works are now in progress along the Ma On Shan Line Stations. These works will allow for the installation of Automatic Platform Gates(APGs) closer to the Shatin to Central Link opening. To avoid impacting normal railway services, these works could only be carried out during the few overnight hours after normal train service.


Automatic Platform Gates Installation Works are on-going along Ma On Shan Line

The installation of Automatic Platform Gates (APG) along the Ma On Shan Line is underway and the installation works were completed at Tai Wai Station in February 2016. Installation works are now on-going at City One, Sha Tin Wai, Che Kung Temple, Shek Mun, Tai Shui Hang and Heng On 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.

RTHK programme shows overnight maintenance and station modification works

When the train service has ended for the day, it is just the beginning of the flurry works for the station maintenance and modifications! Platform modification works are ongoing at Ma On Shan Line stations to facilitate the future 8-car train operation of the Shatin to Central Link. The construction team makes good use of the few overnight hours to carry out works including road closure and lifting of machinery and materials. On the other hand, engineers grab every second to check and maintain the operating railway facilities, so as to provide passengers with highly reliable and efficient train service. RTHK TV Programme “Hong Kong Story” shows us how MTR Corporation’s engineers race with time to finish all the maintenance and station improvement works after the last train departs!

Preliminary Works for Automatic Platform Gates Retrofitting works along East Rail Line and Ma On Shan Line

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 Ma On Shan Line(MOL). APG retrofitting on MOL stations are expected to be completed by 2017, one year earlier than originally scheduled.

Works Arrangement

Retrofitting platform gates in an operating railway is always challenging. To avoid interrupting normal train service for passengers, works can only be carried out for 3 to 4 hours overnight after train service has ended for the day. As some East Rail Line 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.

As most of the East Rail Line and Ma On Shan Line stations are located above ground, extra care must be taken so as not to disturb nearby residents. The noisy part of works overnight will be conducted inside the “mobile sound insulation booth” which reduces noise levels by around 20 decibels.

Progress Updates

Platform Modification Works of the East Rail Line Stations

(Last updated: July 2016)

Since November 2013, the Corporation has started the platform modification works at East Rail Line (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.

MOL Platform Modification Works

(Last updated: July 2016)

Modification works are required at stations along the MOL to tie in with the future 8-car train operation configuration of "East West Corridor". Major modification works 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

The modification works along MOL commenced gradually in end 2012. Works will mainly be carried out during nonoperational hours so the train services of the MOL will not be affected.
