South Korea's GTX higher speed railway

South Korea's GTX higher speed railway
04 February 2020

Our Seoul-based rail technical consultancy team were appointed in 2019 to provide Independent Safety Assessment (ISA) services for the construction of GTX-A , the first line of South Korea's planned higher-speed commuter rail network for its capital city.

Ricardo’s teams will ensure the infrastructure (track and civil engineering) and rolling stock systems (vehicles, communications, signalling etc) will be properly integrated and ready to provide a safe and efficient service once operations commence.

As the appointed ISA, Ricardo’s teams will also assess engineering and maintenance system safety against relevant international standards, including IEC 62278/62279/62425.

Vital new higher speed network for the capital

As the first of three standard-gauge lines planned for the new network, ‘GTX-A’ will extend from Unjeong in the northern reaches of Seoul’s commuter region through to Dongtan in Gyeonggi Province in the south of the city.

With just ten stops along its route, including the city’s main Seoul Station interchange, the line will be capable of speeds of up to 180 km/h, allowing end-to-end journey times of just over 40 minutes, halving those of the current metro services.

As the first deep tunnel project to cross the city of Seoul, the project shares many characteristics of London’s Elizabeth Line (Crossrail), a project that Ricardo Certification, an independent accredited assurance business within the Ricardo group, has supported as the appointed Notified Body since 2012.

Line A is expected to enter service in 2024, with lines B and C adding a further 130km to the network by the end of the decade. Combined, the new three-line GTX network will bring significant new rail capacity to Seoul’s commuter region.>>
