Economically viable, elegant, sustainable and innovative. Commissioned by the South Korean Railroad Research Institute (KRRI), architectural studio ZJA, Woosung D&C, C&SC, GS E&C, SIDstudio and Iv-infra came up with an above-ground solution for an Elevated Light Rail System in a city environment, with less spatial impact than the traditional design.
Lighter, faster, with a greater capacity and less environmentally polluting than other options, the Light Rail System is a popular means of transport in cities. But the raised horizontal structures, which have previously always stood on closely spaced columns, have a negative visual and spatial impact in already jam-packed cities, which therefore often opt for more expensive underground transport systems.
In our innovative structural concept, the solution was found in a slim design with a limited construction height, based on the principle of the I-beam profile. Using a central beam between the tracks, with “flanges” cantilevered outwards, makes it possible - even at places where the structure is around fifteen metres high - to extend the distance between columns to 200 metres without the need for extra stays or cables.
Strong, able to retain its shape and giving passengers a completely open view on one side, our design features transparency and spaciousness, reduces traffic congestion, and leaves room for pedestrians and green space. The network resembles a tendril and its light and animated volume winds across the metropolis at a great height. An asset to the city, and to the people who live, work and travel in it.
