The objective of this study is to verify the hypothesis that cognitive process of railway drivers would be influenced by train speed. The hypothesis is tested by investigating railway drivers' cognitive processes at different speeds of a locomotion. The experiment shows that human performance of railway drivers decreases as the train speed becomes faster. In addition, simple signals outperformed complex signals at every train speed. Therefore, it is suggested to redesign complex signals simpler for improving drivers' human performance. It is also recommended that the Korean railway safety law should be revised to mention requirement of the signal design, especially for the fastest train including KTX. The implications of the experiments are discussed in detail.

The purpose of this paper is to suggest Korean regulatory requirements of railway drivers' qualifications. The qualification of railway drivers is one of major factors that should be managed to reduce human error induced incidents/accidents. We have collected those domestic/foreign cases for suggesting Korean regulatory requirements of railway drivers' qualifications. And we have analysed them to derive some regulatory requirements reducing human error. Finally, we have done preliminary FGI(focused group interview) to vitrificate and validate the regulatory requirements.

This study was performed to evaluate the whole-vibration of the subway drivers. Measurement, evaluation and assessment were based on the ISO 2631. When the vibration levels of the drivers are compared with the health guidance caution zones of the ISO 2631, those of the drivers of the rail maintenance train and the number 3 subway line exceed the limit of the health guidance zones, while those of the drivers of other subway lines drivers are below the limit. This indicates that the rail maintenance train drivers are exposed to potential health risks.

The purpose of this article is to find out and analyze the diverse factors that are incurring stress to the railway drivers, and to depict the moderating effects of personality factors(Locus of Control, Self-Efficacy, and Organization-Based Self Esteem) on the causal relationship between job stressors and job satisfaction in two groups(drivers who experienced accidents and drivers who did not). To attain this purpose, the 212 questionnaires received from the drivers of KORAIL, Seoul Metro, and Seoul Metropolitan Rapid Transit. Most crucial finding was that certain aspects of a driver's personalities measured by locus of control, self-efficacy, and organization-based self esteem showed significant moderating effects in predicting the level of job satisfaction, job stress and accidents. This result implies that the drastic testing of personality factors is so important when staffing drivers in the future.

The purpose of this article is to comparatively depict the organizational effectiveness of two rail firms based on the cognitive response of employees(group of drivers). To attain this purpose, several aspects of current personnel and organization management system and organizational culture are surveyed through questionaire and analyzed by SPSS. The questionaire includes two parts of items. First, it includes items on personnel-related factors such as evaluation system, job, wage, role, leadership and job satisfaction. Second, it includes items on organizational culture model suggested by Rousseau. The major findings are : 1) In general, the cognitive response of drivers in two firms concerning personnel-related aspects is to a certain degree negative. 2) The cognitive response of drivers in two firms concerning culture-related aspects is also awfully negative. 3) Job satisfaction of drivers in the firm A is highly related to role and leadership factors in terms of personnel-related aspects, on the one hand, and to achievement factor in terms of culture, on the other hand. In case of the firm B, job satisfaction of drivers is highly related to personnel evaluation factor as well as role and leadership factors in terms of personnel-related aspects, on the one hand, and to affiliation, power, and bureaucracy factors in terms of culture, on the other hand.

The launch of KTX (Korea Train Express) has brought the changes of people's life. People can get more time to work or enjoy leisure comfortably because the transfer time is decreased. According to these changes, the role of normal trains and express trains' drivers is getting more important. The purpose of this study is to suggest the advanced vision of Korean railway through comparing the domestic driver's qualification requirements of normal trains and express trains with international ones which are more developed.

During normal subway rush hours, a train-driver is in charge of more than 3,000 people on a daily basis. When an emergency event occurs, millions of people and their property come to depend only on the train-driver's ability. After the Daegu subway fire disaster in February 2003, the Railway Safety Act was enacted in October 2004 and the 'Train Drivers' Licensing System' was introduced by the National Railroad Administration in July 2006 to secure and improve protection. This study was conducted to investigate and evaluate the effects of the Train Drivers' Licensing System since the Licensing System was first introduced eight years ago. In addition, the analysis will suggest better policies for the effectiveness of the 'Train Drivers' Licensing System'.

The purpose of this article is to find out and analyze the diverse factors that are incurring stress to the railway drivers, and to depict the relationship among personality, job stress, job satisfaction, and accidents. To attain this purpose, the authors designed the questionnaire based on in-depth interview, scrutinized the factors of stressors, and statistically tested the study themes on the moderating effects of Personality Factors such as Locus of Control, Self-Efficacy, and Organization-Based Self Esteem on the relationship between Job Stressors and Job Satisfaction/Accidents, for the 212 samples received from KORAIL, Seoul Metro, and Seoul Metropolitan Rapid Transit. Resultedly, one of the findings indicate that certain aspects of a driver's personalities, as measured by locus of control, self-efficacy, and organization-based self esteem play important roles in predicting the level of job satisfaction, job stress and accidents.

In line with the expansion of electric railway, reducing carbon emission and optimal train operation are required by economical, eco-friendly and efficient management. Most of the energy consumption in electric railway is consumed by train operation. So it is important that minimize the energy consumption in train operation. An analysis of the operation performance of the new model vehicle which in South Korea, Korail introduced shows that the energy consumption is different in line with the skill level of the engine driver. In this study, the know-how of train operation of a skilled engine driver is systematized by using artificial intelligence, and the technique which supports engine drivers with train operation was offered. As a result of applying in South Korea, the Gyeongbu line by using simulation, it confirmed that the maximum 20% can reduce the energy consumption in comparison with unskilled engine drivers in case of applying the Expert System.
