Singapore’s Sengkang-Punggol LRT: Modernization & Rail Capacity

Singapore’s Sengkang-Punggol LRT Set for Major Modernization with New LRVs

The Land Transport Authority (LTA) in Singapore is poised to significantly enhance the passenger experience and operational efficiency of the Sengkang-Punggol Light Rail Transit (SPLRT) system. The introduction of 25 new third-generation two-car Light Rail Vehicles (LRVs), manufactured by Mitsubishi Heavy Industries, is a key component of a fleet renewal programme. These vehicles, starting passenger operations on July 15, 2025, will replace older models and augment the current capacity, addressing the growing ridership demands of the burgeoning northeast region. This article will explore the key upgrades, operational improvements, and infrastructure investments that underpin this ambitious modernization project, aiming to deliver a more reliable, comfortable, and sustainable public transport system.

Fleet Modernization and Passenger Experience

The SPLRT’s fleet renewal is strategically designed to replace the existing older generation vehicles and increase capacity. The initial deployment on the Punggol West and Punggol East Loops over two weekends will allow for rigorous performance monitoring before weekday operations commence later in July. The new LRVs, featuring two cars per unit, represent a significant increase in passenger capacity compared to the one-car and earlier two-car configurations of the existing first-generation fleet. The 25 new LRVs are part of a wider fleet replacement strategy which will see the decommissioning of the original first-generation LRVs (25 one-car, and 8 two-car units). The remaining 23 new LRVs are scheduled to be introduced progressively from Q3 2025. This comprehensive modernisation includes features for a more comfortable passenger experience such as: ergonomic seating, brighter and energy-efficient LED lighting, clearer LCD passenger information displays, and illuminated door-closing indicators for enhanced safety. Enhanced air-conditioning systems also promise a consistently comfortable onboard environment.

Operational and Maintenance Advancements

The new generation of LRVs incorporates several operational advancements. A key feature is the inclusion of a touch-screen onboard diagnostic panel, designed to expedite fault detection and maintenance procedures. This system will provide staff with enhanced access to onboard equipment, streamlining troubleshooting and reducing downtime. Inter-car doors, incorporated for increased passenger safety, enable quicker and safer evacuations in emergency scenarios. These advancements are not only aimed at improving passenger safety but also improve operational efficiency and reduce the overall time required for maintenance.

Infrastructure Expansion: Depot Upgrade and Power Enhancements

To accommodate the expanded fleet, the SPLRT depot is undergoing a major expansion. The depot will be enlarged from 3.5 to 11.1 hectares to include new stabling and maintenance areas. This critical infrastructural project will improve the overall operational efficiency. Two new reception tracks are being constructed to improve LRV launch times, and the installation of three additional traction power substations will support the increased energy demands of the two-car vehicles. The depot expansion, scheduled for completion by 2027, is vital for enhancing system reliability and enabling a higher service frequency. The project is essential to managing the increased frequency of LRV operations. While service adjustments are anticipated to facilitate the construction, the LTA will provide timely updates to commuters.

Sustainability Initiatives and Community Engagement

In line with its sustainability goals, the LTA is actively pursuing initiatives to responsibly manage the decommissioning of the older first-generation vehicles. Community organizations are being invited to participate in projects to repurpose the vehicles and their components. This initiative builds on the LTA’s prior collaborations with organizations like City Developments Limited, ITE College West, SG Enable, the Singapore Armed Forces, and the Singapore University of Technology and Design, aiming to reduce waste and provide a practical way for organisations to re-purpose materials for community projects.

Conclusion

The Sengkang-Punggol LRT modernisation project signifies a significant step forward for Singapore’s public transport system. The deployment of new third-generation LRVs, alongside the depot expansion and operational improvements, promises enhanced reliability, increased capacity, and an improved passenger experience. The phased introduction of these new vehicles ensures a measured transition, while the focus on passenger comfort, safety, and efficient operations showcases a commitment to providing a world-class urban rail system. The completion of the depot expansion by 2027 will be crucial in sustaining the system’s ability to handle the growing ridership demands of the region. The project reflects broader trends within the rail industry towards leveraging technology for increased efficiency, improved passenger comfort, and sustainable practices. With a continued focus on innovation and investment, Singapore’s LTA is poised to further strengthen its position as a leader in urban rail transportation.
