Featured Projects

LRT Palembang

Supporting Indonesian's First Light Rail Transit System. The Palembang Light Rail Transit (LRT) was Indonesian's first modern LRT system, developed to improve urban mobility and support the successful hosting of the 2018 Asian Games. The 23.4-kilometer network connects Sultan Mahmud Badaruddin II International Airport with Jakabaring Sport City through 13 stations, making it a landmark transportation infrastructure project in Indonesia.

Lemah Abang Station – Cikampek Station Axle Counter Installation

Modernizing Train Detection for a Key Railway Corridor The Lemah Abang–Cikampek railway corridor is one of Indonesia's busiest rail routes, supporting high volumes of passenger and freight traffic between the Greater Jakarta area and West Java. As railway operations continue to grow, modernizing train detection systems is essential to improve operational reliability, enhance safety, and reduce maintenance requirements.

DC Track Circuit to Siemens Axle Counter Migration Bojong Station and Karang Pucung Station

Modernizing Train Detection for Safer and More Reliable Railway Operations As railway operations continue to evolve, modern train detection technologies play a vital role in improving system reliability, reducing maintenance requirements, and enhancing operational safety. Replacing conventional track circuit systems with axle counter technology enables more efficient train detection while supporting the long-term modernization of railway infrastructure.

Filter Module Installation Cibungur Station – Banjar Station

Enhancing Axle Counter Reliability Through Lightning Protection Railway signaling systems operate in demanding outdoor environments where electrical disturbances, particularly lightning strikes, can affect the performance and availability of train detection equipment. Filter modules play a critical role in protecting axle counter systems from electrical surges, ensuring reliable operation and minimizing service interruptions.

Jakarta Kota Station Track Circuit AC Refurbishment

Extending the Reliability of Legacy Railway Signaling Systems. Track Circuit systems are fundamental to railway signaling, enabling accurate train detection and safe traffic control. As infrastructure ages, refurbishment becomes essential to restore performance, improve maintainability, and ensure continued operational reliability without requiring complete system replacement.

Insulated Rail Joint (IRJ) Installation

Improving Train Detection Through Reliable Track Insulation Insulated Rail Joint (IRJ) are essential components of railway signaling systems, providing electrical isolation between track sections to enable accurate train detection and safe signal operation. Proper installation is critical to maintaining signaling integrity, minimizing electrical interference, and ensuring long-term operational reliability.

Empowering railway infrastructure through specialized signaling engineering, delivering safe, reliable, and future-ready solutions for every stage of your project.
