South Korea’s railway system is undergoing a period of intense change and scrutiny, as both government agencies and operators grapple with the dual challenges of aging train fleets and safety threats posed by nature itself. Recent reports and official statements highlight a surge in demand for new railway vehicles, persistent procurement headaches, and a determined campaign to keep the tracks clear of magpie nests—a surprisingly stubborn hazard to smooth train operations.
According to a March 15, 2026 report released by the National Assembly Legislative Research Office, domestic railway operators are now facing a significant increase in the need to replace old rolling stock. KORAIL, the nation’s largest rail operator, has announced plans to begin rolling out new electric trains on Seoul Metropolitan Subway Line 1 starting in 2027. Meanwhile, the KTX-1 high-speed trains, only introduced in 2024, are already slated for replacement around 2033. Seoul Metro isn’t far behind; as of September 30, 2025, a striking 37.8% of its train cars have already exceeded the 25-year durability limit, prompting urgent replacement efforts.
But the path to modernizing South Korea’s railways is not without obstacles. The report, as cited by Newsis, points to recurring problems with delays in delivery and subpar quality control during railway vehicle production and procurement. The current system for verifying whether manufacturers can actually fulfill their contractual obligations has also come under fire for its limitations. These issues aren’t just theoretical—Dawonsys, a major railway vehicle manufacturer, drew controversy after delaying delivery of more than half the ITX-Ma-eum train vehicles for nearly three years following a contract with KORAIL.
In response to mounting concerns, President Lee Jae-myung called for systemic improvements in December 2025. The government quickly followed suit, announcing reforms to the public contract advance payment system on February 25, 2026. Where previously up to 70% of the initial contract amount could be paid in advance, new rules now cap this at 30-50%, with a phased return to 70% only if the proper use of funds is confirmed.
Yet, critics argue that these financial tweaks only scratch the surface. The real culprit, according to the Legislative Research Office’s report, is the so-called ‘two-stage competitive bidding’ method currently used for railway vehicle procurement. In this process, the lowest bidder is selected after a technical evaluation—but that evaluation, the report contends, is too lax. It merely checks if contractors meet a minimum standard, failing to distinguish between companies with different levels of technical expertise and contract fulfillment capabilities.
Both KORAIL and Seoul Metro have tried to patch these cracks from within. They’ve adjusted technical evaluation scoring, expanded penalty criteria for underperformance, introduced more frequent field inspections, and toughened contract management. Nevertheless, price remains the decisive factor in awarding contracts, leaving structural vulnerabilities unresolved.
To address these deep-seated issues, the Legislative Research Office recommends a fundamental shift: moving to a ‘comprehensive evaluation system.’ This would mean scoring bidders not just on price, but also on technical proficiency, production and quality control systems, delivery management ability, and past contract performance. The idea is to choose the winning bidder based on a total score, not just the lowest price tag.
The report goes further, urging the establishment of a full-cycle performance management system. Key indicators—such as delivery compliance rate, initial failure rate, quality stability, and maintenance performance—would be systematically tracked and linked to future bids. This would, in theory, reward reliable contractors and weed out those with spotty records.
Recognizing that not all trains are created equal, the report also suggests tailoring procurement methods to the specific characteristics and technical complexity of each vehicle type. For trains requiring cutting-edge or novel technologies, the report proposes considering negotiation-based contracts or competitive dialogue, rather than a one-size-fits-all approach. "If railway vehicle procurement is operated uniformly, it becomes difficult to adequately reflect the risk level and technological difficulty of each project," the report notes.
While procurement reforms are debated in boardrooms and government offices, KORAIL’s boots-on-the-ground teams are tackling a very different challenge: magpie nests. On March 20, 2026, KORAIL announced a nationwide campaign to remove these nests from overhead catenary lines during the 'Overhead Line Intensive Management Period' from March to May. Why such urgency? Magpie nests, often constructed from twigs and even stray wires, can come into contact with the AC 25kV electrified lines that power trains. The result can be power outages and, inevitably, train delays.
Spring, it turns out, is the magpie breeding season—a time when these enterprising birds favor high places like catenary poles for their homes. In 2025 alone, KORAIL removed 3,788 magpie nests from around overhead lines nationwide. The effort has continued into 2026, with 773 nests removed in just the first two months of the year, alongside reinforced anti-nest facilities to prevent disruptions.
KORAIL’s strategy is meticulous. Any nest found within one meter of energized parts is removed immediately. Those farther away are monitored as caution targets. During breeding season, patrol inspections of overhead lines are conducted at least once daily, and this frequency doubles during severe weather. Emergency repairs include reinforcing or installing new bird prevention devices, especially where nests are too close to live wires.
Looking ahead, KORAIL is investing in the long-term by commissioning detailed design services to upgrade bird habitat prevention facilities. By July 31, 2026, the operator plans to submit comprehensive data on nest formation and removal, which will inform the types and forms of prevention facilities to be installed across the network.
The public is also being asked to pitch in. KORAIL encourages anyone spotting a magpie nest near energized parts of the overhead lines to report it via phone or at the nearest station. Those whose reports help prevent accidents are even eligible for a reward. As Lee Sung-hyung, head of KORAIL’s Electrical Headquarters, put it, "Removing magpie nests is directly linked to train safety. We hope railway users and residents near the tracks will actively report any nests they find."
South Korea’s railways, then, are at a crossroads—caught between the need for robust, transparent procurement processes and the practical realities of keeping the tracks safe from both technical and natural threats. The coming years will reveal whether these reforms and campaigns can deliver on their promise of safer, more reliable train travel for all.
