Singapore’s Land Transport Authority (LTA) has commenced extended night closures and selected full-day shutdowns across parts of the MRT network from February 21, 2026, to accelerate renewal of core rail systems. The move follows the government’s acceptance of recommendations by a national rail reliability task force, targeting upgrades to rolling stock, signalling and traction power infrastructure.
The accelerated works programme includes renewal of trains, modernisation of signalling systems, enhancement of traction power substations and switchgear, and the deployment of standardised condition monitoring systems. Closures are designed to allow longer engineering windows, enabling completion of complex tasks without repeated short-duration disruptions. Bus bridging services and adjusted train schedules will be implemented on affected stretches during works.
The upgrades form part of Singapore’s long-term rail reliability strategy aimed at reducing breakdown risks, improving response times and extending asset life. Investment is expected to support multi-year procurement across rolling stock, wayside equipment, power systems, sensors and predictive maintenance technologies. The programme is positioned as a preventive renewal initiative to strengthen network resilience and sustain ridership growth over the long term.
