Vehicular Underpasses

Singapore’s 4th Mass Rapid Transport Line, the Circle line spans over 35km and an orbital circle route linking all radial routes leading to the city. Stipulated as a “medium capacity” line, each Circle Line train has only three cars instead of the six-car configuration as seen on current MRT lines. Half a million people are expected to use the Circle Line each day.
