Taiwan High Speed Rail – Tsoying Station Design and Construction Published in Jaakko Poyry / Electrowatt Infra Newsletter - November 2004 The construction of the Taiwan High Speed Rail represents one of the most challenging infrastructure projects in the world to date. The 345km long High Speed Rail route runs from Taipei’s main railway station in the North of the country to Kaohsiung City in the South. Tsoying Station will serve as the southern terminus of the HSR system, and as a gateway to and from southern Taiwan. The Station is located in the Tsoying suburban district north of Kaohsiung City, five kilometers north of the existing Kaohsiung Main Railway Station. The Tsoying Station High Speed Rail (HSR) Station is one of six stations of the Taiwan HSR System--the first major build, operate and transfer (BOT) project in Taiwan. Work on the six new stations and two upgrades, costing US $600 million, began in May 2002. They are due to open in October 2005. The entire system has a total cost of approximately US $16 billion. The Tsoying Station Area, in addition to serving as a transportation hub for the greater Kaohsiung metropolitan area, will become an integral part of the surrounding communities. The overall design will include the combined Station plazas, commercial facilities, roadways, utilities and other critical infrastructure within the Station Zone. HSR Tsoying Station has three island, at-grade platforms with passenger concourse levels above. The station will accommodate eight trackways with several through tracks linked directly to the nearby Tsoying HSR Depot. The Station is integrated with a new Taiwan Railways suburban Station, which is adjacent to the HSR Station, with joint access and passenger circulation at concourse level. At the north end of the HSR Station is a connection to the new underground Kaohsiung MRT Station, currently under construction and due to open in 2006. This will provide fast, convenient access to Kaohsiung city centre and the MRT network. Additionally, convenient access is provided for pedestrians, cars, taxis and buses by a new local area road network. The station will be connected to the existing highway system by new ramps linked to the Station, facilitating the smooth flow of vehicular traffic from the east and the south of Kaohsiung.

HSR Tsoying Station – Main Cross-Section
The main station structure consists of a steel reinforced concrete (SRC) frame from ground level to roof level, varying in height from 16m to 24m, supporting a multi-span steel truss wave-form roof structure. The overall plan dimensions of the station structure are 85m wide by 190m long, with a concourse floor 9m above platform level and three upper service area floors towards the front side of the building. Lower level platforms are simple RC structures with Y-shape steel canopies, extending 125m in length to the north side and enclosed within a SRC car park structure for a further 120m to the south side, providing a total platform length of 435m. The parking building is 8050m˛ on plan with three parking levels, is connected to the south side of the station building and contains 1000 car parking and 1600 motor-scooter parking spaces. This is also a steel reinforced concrete structure to 2nd floor level (above platforms), with SRC columns, fire sprayed steel beams and metal deck concrete slabs above 2nd floor level. Foundations for the various structures consist of 600mm and 800mm diameter prestressed concrete piles driven to a design depth of between 29m to 36m through medium silty clayey sand layers to a dense mudstone formation. Pilecaps varied in depth from 1m to 1.8m thick, were generally combined and made longitudinally continuous with shallower 0.5m link slabs. The station structure’s most interesting features included the steel reinforced concrete frame, the use of self-compacting high slump concrete and the large wave form triangulated steel tubular roof trusses. The following aspects proved to be a challenge for construction quality control;
