Project Profile: Palembang Light Rail Transit (LRT), Indonesia

The Palembang Light Rail Transit (LRT) is a 23.4 km elevated urban rail system in South Sumatra, Indonesia, engineered to enhance urban mobility and support major international events like the 2018 Asian Games. The project connects Sultan Mahmud Badaruddin II International Airport with the Jakabaring Sports Complex, utilizing a modern third-rail power system and ballastless slab track technology to provide efficient, high-capacity transit. As the first operational LRT system in Indonesia, it serves as a critical model for subsequent urban rail developments across the nation.

Technical Specifications

The Palembang LRT infrastructure is entirely elevated, running on a viaduct structure to minimize urban disruption. The line utilizes a 1,067mm gauge ballastless slab track configuration, chosen for its high durability, reduced maintenance requirements, and superior ride quality compared to traditional ballasted tracks. Power is supplied via a 750V DC third-rail system, ensuring consistent and reliable energy for train operations. The system is governed by a fixed block signalling system, which maintains safe headways between trains and ensures operational efficiency across the 13-station route.

The rolling stock, manufactured by state-owned PT Industri Kereta Api (INKA), consists of eight Light Rail Vehicle (LRV) trainsets. Each vehicle is designed to accommodate up to 534 passengers, blending seated and standing capacity to handle peak commuter loads. These LRVs are engineered for urban transit, with a maximum operational speed of 80 km/h, facilitating a significant reduction in travel time between the airport and the city’s southern sports complex.

Key Takeaways

• Urban Development Catalyst: Served as a critical infrastructure backbone for the 2018 Asian Games, establishing a permanent transit corridor that stimulates economic activity and connectivity between the airport and key city zones.
• Showcase of Domestic Capability: The project was successfully delivered through a collaboration of Indonesian state-owned enterprises, including PT Waskita Karya (construction), PT KAI (operations), and PT INKA (rolling stock), demonstrating national self-sufficiency in complex rail projects.
• Adoption of Modern Rail Technology: Implemented advanced systems such as a 750V DC third-rail power supply and ballastless slab track, setting a new standard for LRT construction in Indonesia by prioritising long-term durability and reduced maintenance costs.
