The full Tuen Ma Line (TML) commenced services on 27 June 2021, providing enhanced connectivity to the rest of Hong Kong’s rail network and more alternatives for passengers travelling to different districts.

As the first section of Shatin-to-Central Link (SCL) to commence passenger services, TML connects TML Phase 1 and West Rail Line via two new stations – Sung Wong Toi and To Kwa Wan, together with new platforms at Hung Hom and Ho Man Tin Stations. The 56km long new line runs through 27 stations from Tuen Mun to Wu Kai Sha.

Arup has been involved in multidisciplinary detailed engineering design services for stations, tunnelling works and associated infrastructure in the entire TML, significantly improving cost and time savings, sustainability, safety performance and quality of works.

We were the Lead Consultant for the detailed design of Sung Wong Toi, To Kwa Wan and Ho Man Tin stations, and undertook the reference design of twin 1.7km tunnel boring machine (TBM) running tunnels from Ho Man Tin to Sung Wong Toi stations.

In view of a large number of archaeological relics from Song Dynasty found during excavation in Sung Wong Toi station located within the historical footprint of Sacred Hill, we re-designed the station to protect large relics in-situ, allow reinstatement of the relics at original level and orientation, and accommodate two big display cabinets inside the station concourse for education purposes.

In response to the tight physical constraints along the line, we designed To Kwa Wan station box in a stacked platform configuration to reduce the station footprint and excavation width as the box is very close to a number of old buildings with shallow and deep foundations. Mixed ground TBM and cut-and-cover methods were used for the running tunnels and pedestrian subways.

We also provided tunnel and shaft design for the tender and detailed design of the section between Hin Keng and Diamond Hill stations, making concerted multidisciplinary input from our tunnelling, rail, structures, and E&M disciplines.

We’re proud to have contributed to this much-needed transport link that strengthens the connectivity from east to west of the city, expanding rail services to different districts and facilitating development in the nearby areas. ” (c) Arup Jason Wong Director and East Asia Rail Leader
