The system is managed in conformity with a semi-nationalised hybrid regulatory framework; construction and procurement fall under the purview of the Land Transport Authority (LTA), a statutory board of the government that allocates operating concessions to the for-profit private corporations SMRT and SBS Transit. These operators are responsible for asset maintenance on their respective lines, and also run bus services, facilitating operational synchronicity and the horizontal integration of the broader public transportation network.
