In Korea, the number of railroad accidents is decreasing, but the scale of railroad accidents tend to be growing large. On considering the opening of the high speed railway in 2004, the problem of railroad safety is very important. The purpose of this study is to make plans for improving railroad safety of Korea. To make this plan, we generally analyzed the future railway traffic, and reviewed annual statistics of railroad accidents trend and case studies of foreign railway accidents.

The purpose of Overall Railroad Safety Audit(ORSA) is to prevent railroad accidents, and, every two years, to inspect and evaluate whether or not railroad operators faithfully adhere to railroad safety guidelines in accordance with the Railroad Safety Law. However despite of the many contributions of ORSA, due to lots of railroad accidents such as train failures and derailment caused track irregularity this year, it has been recently considered that ORSA will be renewed into Safety Certificates System as a complement. In order to guarantee railroad safety, new Safety Certificates must included appropriate safety standards considering current our country's railroad conditions. Therefore, in this study we're going to compare safety components of foreign audit system with those of Airlines field, based on ORSA's contents for years, to review Safety Management System and Safety Culture, as a result, we'd like to suggest to updated Railway Safety Standards.

On 16Dec. 1999, It was 100 years since the opening the first railroad section of 33.2km on Sep. 1899, Korea High Speed Railroad had a successful trial run of 200km/h on test track section. And the test speed 300km/h was achieved an 28 June 2000 during continuous commissioning. In the 21st century, the High Speed Railroad will be opened commercially in Korea and will contribute to technical development. Now, it is necessary to re-evaluate the role of railroad in modern society and to activate the railroad system. Ultimately, the competitive power of nation will be strengthened with energy saving, reduction of pollution and transportation cost. It conclusion the railroad system have to be expaned about 50% of total transportation to make preparations for reopening of Eurasia silk route through KyungEu railroad connection.

As the opening of Korea Railroad Express on April 1, 2004, it has extended the transportation capacity of railroad, and decreased the time and moving cost. Railroad Express is industry composed of transportation, advanced technology, and grand project for synthetic plan. Hence, here now, as the anniversary of Railroad Express, we should analyze the overall effect of Korean Economy by KTX. relationship with other industry, social and cultural change. That is the key point what is the change during the year and how we catch the chance to develope the Korea Railroad for the national economy. The KTX has overcome the speed which the traditional railroad not been. But the Express has a weakness in searching of customer or goods. KTX is helped by electronics and telecommunications. so we need to find new industry in relation to KTX. And we should have open mind and vision for international railroad.

Since the railroad accidents due to the human error occupy considerable proportion among the railroad accidents, it is necessary to study the propriety of the physical examination system for the railroad workers. Our government is promoting some systematic supplementation for railroad safety on the basis of the Railroad Safety Act. In this paper, we perform a comparative analysis of domestic and foreign physical examination systems for railroad workers. We also compare the physical examination system for public officials with that for railroad workers. Then we consult expert opinions of the Korean Society of Occupational and Environmental Medicine. Through the comparative analysis, we provide useful information that is needed to amend the physical examination system.

Present status of railroad slopes through the field investigation in 26 selected slopes and/or rockfall at risk was grasped. From the evaluation of field data, main characteristics of railroad slopes are that 1) the possibility of failure by rockfall is high, 2) the Possibility of failure by slope itself is low and 3) rockfall's risk at the in and out part of tunnel is especially high. To maintain the railroad slopes systematically and reasonably, it is necessary to make and to use the database of slopes information along the railroad. Furthermore, through the construction of basic slopes' information, maintenance system of railroad slopes was developed in connection with IR-DiPS(Intelligent Railroad - Disaster Prevention System) in the future.

Test evaluation field of railroad system that safety and reliability are important is to verify basic performances of unit products and system that were producted according to the specifications. Also, it is important works that verify finally in respect to commercialize verifying reliability and safety. As one part of system technology, this field is to construct database based on know-how of accumulated technology till now than high technical idea and, is to construct test evaluation system of railroad system that can utilize the constructed database. According to the necessity, our researchers investigated good measuring system of foreign country and performed research on performance test and evaluation technology of high-speed tilting vehicle that suits to domestic state.

In this paper, we propose the ergonomics design method in shape design applicable which considers the user interface for railroad. This study focuses on ergonomics design and sensibility engineering design, user interface, which should be considered from the conceptual design stage of the rolling. Human's sensitivity and User Interface of railroad investigated ergonomics studies of several type. The sensibility engineering design made approach of user center design in railroad design. New design railroad to satisfaction passenger's various desire, to safety and convenient through high technology, to sufficient passenger's aesthetic sense. Therefore, we have application to properly of ergonomics design element in railroad design. we expert visual design and user interface help greatly in excellent railroad design.

Derailment due to wheel failure would cause a tremendous social and economical cost in service operation. It is necessary to evaluate quantitatively the safety with respect to high-speed train. Although the safety of railway wheel has been ensured by an regular inspection, all critical defects cannot be detected in inspection cycles and the wheel has been replaced because a defect quickly become critical for safety. Therefore, it is important to calculate quantitatively the fracture limit and remnant life of damaged railway wheel in wheel-rail system. In present paper, the critical crack size of wheel for high-speed train is simulated based on fracture scenario and the safety of wheel is evaluated.
