Technical Conditions for 300 MHz Radio Train Control
Overview
On October 28, 2026, the Ministry of Internal Affairs and Communications received a partial report from the Information and Communications Council on the technical conditions for a 300 MHz radio train control system, as part of Inquiry No. 2033, “Technical Conditions for the Advancement of Land Mobile Radio Communications for Business Use.” Based on the report, the Ministry plans to establish the relevant regulations.
Key points
- The Ministry of Internal Affairs and Communications received a partial report from the Information and Communications Council on the technical conditions for a 300 MHz radio train control system.
- Based on the report, the Ministry of Internal Affairs and Communications plans to establish the relevant regulations.
- Radio train control is a method in which trains determine their own positions and are controlled through two-way information exchange between onboard and ground equipment.
Overview
Railways are public infrastructure that supports daily life and economic growth, while a decline in the working-age population due to population decline and aging, as well as the aging of railway facilities, is expected.
As part of Inquiry No. 2033, “Technical Conditions for the Advancement of Land Mobile Radio Communications for Business Use,” dated May 17, 2013, the Information and Communications Council examined the technical conditions for a 300 MHz radio train control system and issued a partial report.
Impact
The original text states that simplifying ground equipment contributes to more efficient maintenance work and fewer transport disruptions.
Details
The conventional method using track circuits and signals has a long history and a high level of safety. The radio-based method replaces control centered on conventional ground equipment by using information and communications technology to distribute control functions between ground and onboard equipment.
Train position is detected without track circuits; moving trains determine their own positions and communicate wirelessly in both directions between onboard and ground equipment. Adoption is expected in both urban and intercity railways.
