- institute obtains Level 1 Good Software (GS) certification for its Rolling Stock Remaining Life Evaluation Program -


UIWANG, South Korea – FEBURARY 16 – The Korea Railroad Research Institute (President: Dr. Seok-youn Han) has developed the Rolling Stock Remaining Life Evaluation Program and obtained the Level 1 Good Software (GS) certificate, a national certification program based on the standards of the International Organization for Standardization (ISO).

The Rolling Stock Remaining Life Evaluation Program is a software program that quickly and accurately performs complete rolling stock safety diagnosis to ensure safety of the trains reaching their design life.

Thanks to the Level 1 Good Software (GS) certificate, the program has been registered in the digital service mall operated by the Public Procurement Service of the Korean government and has also been designated for the Unit Price Contracts for Third Parties Program and the Preferential Purchasing Program for Public Organizations.

A Good Software (GS) certificate is a national certification program awarded to software with excellent functional capability, efficient performance, compatibility, usability, reliability and security in accordance with international standards of the International Organization for Standardization (ISO).

The Rolling Stock Remaining Life Evaluation Program calculates remaining life by measuring sensor signals on vulnerable parts with complex structures that are welded together, such as railway car-body and bogie.

The program has significantly reduced evaluation time from over a week to less than few hours.

In addition, since it can simulate various operating conditions in advance according to field situations, it is possible to make plans for utilization of rolling stock as passenger numbers increase.

“KRRI will expand its research and development by adding a real-time online function to monitor the aging of rolling stock in real time, so that risk can be identified in advance,” said KRRI Chief Researcher Hyun-kyu Jun.

“Rolling stock designed to operate for more than 30 years ages slowly due to the fatigue loading during the railway operating service. Therefore, predicting remaining service life is very critical to ensure safety,” said KRRI President Dr. Seok-youn Han. “KRRI will make greater efforts to develop prestigious K-railway technologies that keep people safe based on cutting-edge science and technology.”
