Korea's KTX high-speed trains let passengers board without ticket gates, checking fares onboard instead, and conductors verify tickets through an app and handheld devices without waking sleeping riders. That differs from most European countries, where inspectors ask passengers to present tickets directly.
Railway fare evasion cases numbered 270,181 last year, according to data that Rep. Cho In-chul of the Democratic Party of Korea, a member of the National Assembly's Land, Infrastructure and Transport Committee, obtained from Korail and released on the 24th. Korail carried 146.24 million passengers last year — 92.71 million on KTX trains and 53.53 million on conventional services — meaning about two in every 1,000 riders were caught.
No Gates, No Interruptions: Technology Layered on Trust
The system rests on the assumption that passengers board with valid tickets. Checking fares onboard rather than blocking entry at gates works only if most riders hold proper tickets. The detection rate of just 0.18% suggests that trust has largely held.
Technology has been added so conductors no longer need to wake every passenger. For reserved seats, crew members are understood to confirm ticket issuance on handheld devices rather than asking each rider for a ticket. For unreserved seats, passengers scan a QR code at their seat using the Korail Talk app in a "self check-in" that replaces inspection by crew, and the check-in is automatically transmitted to crew devices.
Korail piloted the service on KTX unreserved seats in October 2023 and has since extended it to ITX-Saemaeul trains. The aim is to spare passengers the inconvenience of being checked while sleeping or resting.
Europe takes a different approach. According to Interrail guidance, inspectors in most European countries ask passengers to present tickets for visual checks, and some countries scan barcodes. In France, Italy and Spain, travelers sometimes must pass through platform validators before boarding.
Germany has extensive public transit without ticket gates, but the Association of German Transport Companies (VDV) estimates fare evasion at about 3.5% and annual losses at roughly 300 million euros (about 450 billion won, based on conversions in Korean media reports). Germany treats fare evasion as a criminal offense, fueling continuing debate over whether to repeal that provision.
Korail maintains order through surcharges. Under Article 10 of the Railroad Enterprise Act, confirmed fare evasion can draw a surcharge of up to 30 times the standard fare. Korail raised the surcharge for boarding without a ticket from 0.5 times to one times the original fare in October last year. Cases of fare evasion involving passengers without tickets subsequently fell to an average of 679 a day, or 70.6% of the 961 recorded in the same month a year earlier, the operator said.
Challenges remain. The 0.18% figure is based on cases detected, so it excludes undetected fare evasion, and it is calculated differently from the German estimate, limiting direct comparison.
Over the past three years, from 2023 to 2025, 795,086 fare evasion cases were detected, but only about 1,600 were referred to the railway judicial police. Critics note that there is no way to collect surcharges on the spot from passengers who refuse to pay, and that systems for tracking habitual and repeat offenders are inadequate.
A design that trusts passengers and checks tickets onboard, combined with mobile technology, has kept detection rates low, but gaps such as managing repeat offenders remain.
