What interCon Systems does

InterCon Systems Co., Ltd. (인터콘시스템스(주)) is a privately held South Korean specialist in railway vehicle control and door systems, founded in May 2001 and headquartered in Suwon, Gyeonggi-do, with a separate R&D Center in Anyang and a manufacturing facility in Hwaseong. The company designs and manufactures two integrated product lines: train control systems — TDCS (Train Diagnosis and Control System) for high-speed trains, OBCS (On Board Computer System) for KTX, and TCMS (Train Control and Monitoring System) for metros, trams, and EMUs — and Entrance Door Systems including a proprietary Door Control Unit (DCU). Core technology is built on semiconductor, embedded software, and data communication stacks using the international TCN (IEC-61375) standard, real-time operating systems, and fully redundant hardware architectures certified to SIL standards.

The company was the first in Korea to localize the KTX TDCS (2007) and KTX-1 OBCS (2016), creating proprietary technology IP in safety-critical high-speed rail control. The business model is B2B enterprise: project-based sales of customized hardware/software subsystems directly to state-owned railway operators and train OEMs, with one-stop service spanning design, production, delivery, and maintenance. Pricing is not publicly disclosed and contracts flow through government procurement processes. Revenue reached KRW 35,365 million in FY2025.

InterCon supplies Korail, SR Corporation, Seoul Metro, Busan Transportation Corporation, and international operators including TCDD (Turkey), TRA (Taiwan), Singapore MRT, Malaysia KV-MRT, Brazil metro operators, Incheon Airport Railroad, Shenzhen Metro, Tanzania Railway, and Almaty Metro (Kazakhstan), with a strategic OEM relationship with Hyundai Rotem. Quality and safety certifications include ISO 9001 (2006), ISO/TS 22163 IRIS (2023), and ISO 14001 (2026). In April 2024 the company raised approximately $34.8 million from IGen Private Equity, and in January 2026 appointed Kim In Hyun and Phillip S. Jeon as co-CEOs.
