KRRI Holds International Seminar on Innovating Railway Transportation for Carbon Neutrality

[1] Role of railway for achieving carbon neutrality, technological and policy trends [2] Roadmap by field, such as transportation policy, railway vehicle, infrastructure and electronic signal [3] Status of Korean railway technology research for carbon neutralitySEOUL, South Korea – FEBRUARY 20 – The Korea Railroad Research Institute (President: Dr. Seok-Youn Han) held the KRRI’s 28th Anniversary International Seminar under the theme “Innovation of Railway Transportation for Carbon Neutrality” at COEX Conference Room E, Seoul, on Feb. 20th. This seminar offered an opportunity to look into the status of development of railway transportation technologies from home and abroad as well as policy trends for carbon neutrality, suggesting a future vision of railway transportation expanding on world-class K-carbon neutral railway technology.During the event, Lucie Anderton, Head of the Sustainable Development Unit at International Union of Railways (Union Internationale des Chemins de fer, UIC), will deliver a keynote lecture under the theme Status of Carbon Neutrality by Global Railways.This will be followed by a keynote lecture by Dr. Jae-hoon Lee of T-Lab Transportation Policy Institute on the theme Realization of Carbon Neutrality and a Bigger Role of Railway. Dr. Lee will suggest a targeted share of rail freight transport and implementation measures including financing of investment resources. Presentation sessions consist of six themes: Transportation Strategies and R&D for Carbon Neutrality (presented by Kook-hyun Moon, Senior Researcher at KRRI); 2050 Carbon Neutrality Roadmap for Railway Industry and Action Plans (presented by Cheol-kyu Lee, Principal Researcher at KRRI); Measures to Increase the Share of Rail Freight Transport for Achieving Carbon Neutrality Targets in the Transportation Sector (presented by In-mook Lee, Senior Researcher at KRRI); Developing Technology for Higher Efficiency Railway Vehicles (presented by Sung-hoon Choi, Principal Researcher at KRRI); Carbon Neutrality of Hydrogen Railway and Efficiency Improvement Technology Based Railway Electronic Signal System (presented by Joon-hyoung Ryu, Head of Propulsion System Research Department at KRRI); and Carbon Neutrality in Railway Construction (presented by Ji-hwan Kim, Senior Researcher at KRRI).Senior Researcher Kook-hyun Moon will introduce carbon neutrality related policy trends and the status of R&D in the domestic and overseas transportation sectors as well as suggesting carbon neutrality policies and R&D strategies. Principal Researcher Cheol-kyu Lee will present the trends in the railway industry for achieving carbon neutrality by 2050, a carbon neutral roadmap and status of low carbon technologies, and action plans for achieving carbon neutrality. Senior Researcher In-mook Lee will introduce changing mobility and logistics environments and suggest tasks to be completed for securing competitiveness of the railway industry in terms of mobility and logistics.Principal Researcher Sung-hoon Choi will suggest the future direction of high-speed rail from perspectives of higher speed and energy efficiency and present core technologies for improving energy efficiency of rail vehicles, such as inboard bogies, and relevant policies.Joon-hyoung Ryu, Head of Propulsion System Research Department, will introduce carbon-free hydrogen railway, rail integrated power grid, and train control technologies for improving energy efficiency.Senior Researcher Ji-hwan Kim will present carbon-neutral strategies in railway construction and the status of development of eco-friendly railway construction technologies.“Achieving carbon neutrality in transportation sector requires swift transition into railway, one of the most eco-friendly means of transportation,” said KRRI President Dr. Han. “KRRI is committed to developing carbon-neutral railway technologies that can help overcome climate crisis and promote a sustainable society.”※ Attachment: “Innovation of Railway Transportation for Carbon Neutrality” Poster and InvitationPress ContactsYongmook KANGKorea Railroad Research Instituteymkang@krri.re.kr+82 31 460 5184

KRRI’s Automatic Plane Positioning System for Railway Bogie Frames Named Innovative Transport Techno

- Automatically adjusts bogie frame height -UIWANG, South Korea – FEBRUARY 6 – The Korea Railroad Research Institute (President: Dr. Seok-Youn Han) has developed, as part of Government SME Support Programs, an automatic plane positioning technology for railway bogie frames which was designated Innovative Transport Technology (No. 61) by the Ministry of Land, Infrastructure and Transport.This technology aims to automatically adjust the height of a bogie frame so that it can be horizontal prior to measurement, machining or fabrication.The bogie is a drive wheel assembly which supports a railcar and transmits traction and braking power to neighboring rail cars.Measurement, machining or fabrication of a bogie frame which whose position is not horizontal may result in quality issues and degrade train performance.Also, fatigue cracks may occur in the bogie frame, which could result in an accident. For these reasons, it is essential to maintain the bogie frame horizontal.Previously, a bogie frame was leveled manually with trial-and-error process so that the bogie frame could be horizontal. Though conducted by skilled personnel, these manual leveling works cause a number of problems such as decreasing work efficiency, worker fatigue, and falling accidents.The automatic plane positioning system, which is key to the technology, is a tailored factory automation system using advanced precision technologies like laser sensors. Upon the start command of the worker, a bogie frame will be automatically leveled to make it level and horizontal.The system consists of four components: an automatic height measurement device for the bogie frame, automatic plane height adjustment device, control and communication device module for integrated control of different devices, and monitoring device for checking work progress and relaying commands.※ Related research project- Title: Development of leveling and positioning technologies for bogie frame of railway vehicle system using an automatic height control system with a flat base (Government SME Support Programs)- Research period & budget: Jan. 2023 - Dec. 2023 / KRW 133 million - Person in charge: Sung-il Seo, Principal Researcher at KRRIThis technology allows to make the bogie frame horizontal in a safe, speedy and accurate manner, with a single touch of the screen.Flatness accuracy has been significantly improved from 2mm to 0.5mm. Also, the leveling time spent on each bogie frame has been sharply reduced from 120 minutes to 20 minutes. In addition, automation and mechanization have eliminated safety risks and accidents for workers.This technology has been acknowledged for its excellent fatness accuracy by TÜV-SUD, an international third-party certification organization, and was selected as one of the Top-10 Railway Technologies by the Korean Society for Railways in 2023.This technology has been developed in cooperation with Hyungje Iron Industry Co., Ltd., as part of KRRI’s SME Support Programs. Previous manual leveling of bogie frames has been replaced by this technology to improve productivity and reduce costs. A purchase contract has been completed with railcar builders and railcar component manufacturers, and mass production of the present system is under way.A technical presentation will be given to railway operators so that the technology can be applied not only to the railcar manufacturing phase but also to the maintenance phase.“The automatic plane positioning technology for bogie frames serves as a fundamental technology designed to ensure safety of the driving system,” said Sung-il Seo, Principal Researcher at KRRI. “We will continue our research to apply this technology to other industries requiring plane leveling, including automotive, energy generation, machinery, semiconductor, and aerospace.”“KRRI is committed to concentrating its research capabilities to promote railway safety and expanding on-site technical support to improve productivity and competitiveness of railway SMEs,” said KRRI President Dr. Han.※ Attachment: Images of the automatic plane positioning technology for railway bogie framesPress ContactsYongmook KANGKorea Railroad Research Instituteymkang@krri.re.kr+82 31 460 5184
