The State Railway of Thailand (SRT) has ordered an upgrade in rail safety measures, aiming to implement the 'ATP' system.This system meets international standards.It will be used to control train operations, minimizing risks from human errors, with installation on 120 locomotives underway and set for use this year, starting with the Eastern Line pilot.
Anan Phonimdaeng, Deputy Governor and Acting Governor of the State Railway of Thailand (SRT), revealed after the SRT Board meeting chaired by Piyapong Chiwattanakulpaisan, Director-General of the Department of Highways, that the board acknowledged the report on a recent accident in the Asoke area. They instructed related agencies to urgently enhance rail safety measures and coordinate closely with all relevant sectors to prevent accidents and build public confidence in rail services.
Anan stated that most rail accidents still result from human error despite strict existing regulations, procedures, and operational standards. To further improve safety effectiveness, modern technology must be introduced as a supporting tool to reduce risks from human operational errors.
Accordingly, SRT has chosen to use the Automatic Train Protection (ATP) system based on the European Train Control System (ETCS) Level 1 standard, an internationally recognized signaling and rail safety system widely used worldwide. This system helps control train operations according to safety requirements and reduces accident risks caused by driver mistakes.
. Currently, the ATP installation project is underway, involving equipment installation both on the ground and on train units, alongside preparations for system testing before official operation. SRT confirms that the chosen technology meets international standards, is highly efficient, and integrates effectively with the existing rail network.
Anan explained that although society has suggested employing artificial intelligence (AI) or closed-circuit television (CCTV) systems for increased monitoring, in practice, ATP remains the internationally accepted primary system. It is specifically designed to control train safety and is already in use on the Red Line suburban railway project, demonstrating its efficiency and reliability.
The ATP system continuously monitors train movement via railway signal systems. If the driver exceeds speed limits, fails to reduce speed as required, or does not stop at designated points, the system immediately alerts the driver. If there is no response within a set time, the system automatically slows the train and, if necessary, applies the brakes to prevent accidents and reduce potential damage.
Anan added that ATP has now been installed on a total of 120 locomotives, including 50 QSY diesel-electric locomotives that come equipped with the system and 70 older locomotives that have already been retrofitted with ATP. Preparations are underway to install ATP on diesel railcars, with the procurement and installation process currently open for bidding.The bidding process for procurement and installation is ongoing.Regarding the railway tracks, SRT is installing the ATP system on the double-track railway project.Phase 1,covering all routes, with over 300kilometers completed.SRT is preparing to test the installed systems and plans to gradually launch the system route by route rather than all at once. The target is to begin operations on the Eastern Line by 2026.
