MEDAN — State-owned railway operator PT Kereta Api Indonesia (Persero) Divisi Regional (Divre) I North Sumatra, in collaboration with the Class I Railway Technical Center (BTP – Balai Teknik Perkeretaapian) of the Ministry of Transportation, has successfully carried out a comprehensive joint inspection along the inactive railway corridor connecting Rantauprapat Baru Station and Aek Nabara Station.

This strategic joint review was launched to verify the structural integrity, safety, and overall readiness of the railway infrastructure. As part of a broader national initiative to connect the island of Sumatra through a modern rail network, the inspection marks a crucial step toward reviving and eventually commissioning this vital transport corridor.


Main Facts of the Inspection

The joint inspection focused on an 18.5-kilometer section of track that links Rantauprapat Baru Station to Aek Nabara Station in North Sumatra. This particular corridor is a key segment of the larger Rantauprapat–Kota Pinang railway development project, which was initiated by the Directorate General of Railways (DJKA) under the Indonesian Ministry of Transportation. Although construction of the tracks and basic facilities has been largely completed, the line has not yet been opened for commercial passenger or freight operations.

+----------------------+--------------------------------------------------+

The joint team from PT KAI Divre I North Sumatra and BTP thoroughly examined the entire physical infrastructure of the line. The scope of the assessment included:

  • The alignment, stability, and wear of the steel rails and concrete sleepers.
  • The load-bearing capacity and structural health of railway bridges spanning local river systems.
  • The architectural and functional readiness of the station buildings, platforms, and passenger boarding facilities.
  • The integrity of the signaling systems, telecommunications wiring, and level crossings.

Beyond assessing technical viability, the inspection aimed to establish a robust security blueprint. Because the line is currently non-operational, it is highly vulnerable to illegal encroachment, asset theft, and malicious vandalism. By securing the corridor now, PT KAI and BTP intend to minimize future rehabilitation costs and ensure that when the line is officially greenlit for operations, it can transition to active service seamlessly and safely.

1. Inception and Construction Phase (2017)

The development of the Rantauprapat–Kota Pinang railway line was officially launched in 2017. Recognized as a National Strategic Project (Proyek Strategis Nasional or PSN), the project was heavily funded by the state budget through the DJKA. The primary goal was to bypass congested road networks, reduce logistics costs for North Sumatra’s thriving agricultural sector, and provide a reliable mass transit alternative for residents of the Labuhanbatu Regency and its surroundings.

2. The COVID-19 Disruption (2020)

In early 2020, the global COVID-19 pandemic struck Indonesia, forcing the central government to urgently reallocate state budgets toward healthcare, public subsidies, and pandemic mitigation. Consequently, funding for several major infrastructure projects, including the Trans-Sumatra Railway, was temporarily frozen or significantly reduced. Physical construction on the Rantauprapat–Kota Pinang segment ground to a halt, leaving the newly laid 18.5-kilometer track between Rantauprapat Baru and Aek Nabara in a dormant, non-operational state.

3. Post-Pandemic Preservation and Current Joint Inspection

During the post-pandemic recovery phase, the Ministry of Transportation and PT KAI shifted focus toward preserving existing assets. Left unchecked, tropical weather, soil erosion, and human interference can rapidly degrade idle railway tracks.

To prevent this, PT KAI Divre I North Sumatra and BTP organized the recent joint field inspection. Teams traveled along the corridor, conducting hands-on measurements, structural testing, and safety audits to document the exact status of the line’s infrastructure.


Supporting Data and Legal Framework

The maintenance, protection, and eventual operation of the Rantauprapat Baru–Aek Nabara corridor are backed by strict national laws and supported by regional demographic trends.

Legal Status as a National Vital Object

Under Law No. 23 of 2007 concerning Railways, all railway infrastructure—including tracks, stations, bridges, signaling installations, and supporting facilities—is officially designated as a National Vital Object (Objek Vital Nasional or Obvitnas).

                    LAW NO. 23 OF 2007 ON RAILWAYS
                                  │
         ┌────────────────────────┴────────────────────────┐
         ▼                                                 ▼
National Vital Object (Obvitnas)                   Public Welfare & Safety
• High strategic value to the state.               • Crucial for mass transit.
• Protected by federal security laws.              • Severe penalties for vandalism.

This legal status means these assets are recognized as having high strategic value to the state, and any disruption to them could threaten national security, public welfare, and economic stability. Under this law, unauthorized access, vandalism, theft of railway components (such as track clips or signaling copper wires), or any actions that compromise the safety of the rail network are federal offenses subject to severe criminal penalties.

Technical and Regional Data

  • Track Length: 18.5 kilometers of single-track rail, designed to accommodate standard diesel locomotives and passenger/freight cars used across the Sumatran network.
  • Target Population: Labuhanbatu Regency, which has a population exceeding 500,000 residents, stands to benefit directly from this corridor.
  • Passenger Demand at Rantauprapat: Rantauprapat Station, the current terminus of the active line from Medan, has experienced a steady increase in passenger volume. Post-pandemic passenger numbers have rebounded strongly, creating an urgent need to extend the rail line south to distribute traffic and ease pressure on the existing terminal.
  • Freight Logistics Potential: North Sumatra is a powerhouse for crude palm oil (CPO) and rubber production. The Rantauprapat–Kota Pinang line runs directly through major plantation belts, making it highly valuable for future industrial cargo transport.

Official Responses and Strategic Statements

During the inspection, regional railway leaders emphasized the strategic importance of the corridor and the necessity of maintaining high safety standards.

Anwar Yuli Prastyo, the Public Relations Manager of PT KAI Divre I North Sumatra, highlighted the preventative nature of the joint operation:

"This joint inspection with the Railway Technical Center is a proactive measure to thoroughly assess the current state of our infrastructure. The Trans-Sumatra rail project is a National Strategic Project that holds immense promise for the region. Because construction was halted due to the COVID-19 pandemic in 2020, we must ensure that the existing assets remain in prime condition.

Our primary goal is to mitigate safety risks and prevent vandalism. Because these assets are legally categorized as National Vital Objects under Law No. 23 of 2007, we have a statutory duty to protect them. We want to guarantee that whenever the government decides to officially activate this line, every single component is ready, meets our strict safety parameters, and is fully fit for service."

Representatives from the Class I Railway Technical Center (BTP) of the Ministry of Transportation added that maintaining technical compliance is essential for passenger safety:

"An idle railway track is subject to environmental wear, soil shifting, and potential structural issues that are not always visible at a glance. By performing these physical joint inspections, we can pinpoint areas requiring structural reinforcement, particularly bridges and drainage channels. This ensures that when commercial operations eventually begin, the safety of our passengers and crew will not be compromised."


Future Implications for North Sumatra

The successful maintenance and eventual activation of the Rantauprapat Baru–Aek Nabara railway line will have profound economic, social, and logistical implications for the province of North Sumatra and the wider island.

1. Decongestion of the Trans-Sumatra Highway

Currently, the primary transit route for passengers and cargo across Sumatra is the Trans-Sumatra Highway (Jalan Lintas Sumatera). This highway is notorious for heavy traffic congestion, high accident rates, and rapid road surface wear caused by overloaded cargo trucks.

Activating the rail corridor will shift a significant portion of passenger traffic and heavy bulk freight from the roads to the rails. This transition will reduce road maintenance costs for the government, lower carbon emissions, and significantly improve safety for road commuters.

   • High maintenance costs            • Lower logistics costs
   • Frequent accidents                • Reduced carbon emissions
   • Severe travel delays              • Reliable, scheduled transit

2. Boosting the Regional Economy

By extending the railway network further south into Aek Nabara and eventually to Kota Pinang, agricultural producers will gain direct access to a highly efficient logistics pipeline.

Crude palm oil (CPO) and rubber can be loaded onto cargo trains close to the plantations and transported directly to the Belawan Port in Medan for export. This streamlined supply chain will lower shipping costs, making North Sumatran agricultural products more competitive in global markets.

3. Fostering Regional Equity and Social Connectivity

For local communities, the extension of the passenger rail service will provide an affordable, reliable, and comfortable mode of transport. It will connect rural and semi-urban populations in Labuhanbatu directly to the provincial capital of Medan and other major urban hubs. This improved connectivity is expected to stimulate local tourism, open up new employment opportunities, and grant residents better access to higher education and advanced healthcare facilities.

By safeguarding the 18.5-kilometer Rantauprapat Baru–Aek Nabara line today, PT KAI Divre I North Sumatra and BTP are protecting a vital public asset. Their efforts ensure that this critical piece of the Trans-Sumatra puzzle remains viable, secure, and ready to drive regional progress the moment the engines start running.
