A Vigilance control is a device fitted in the driving cab of a railway train to ensure that the driver is alert on the job. A simple vigilance control requires that the driver press a button at intervals not less than a certain amount and not more than another amount of time. If the driver fails to operate the vigilance control within those limits, a hooter sounds, and should the driver still doesn't operate the vigilance control then the brakes are applied. If the driver falls asleep or takes ill, then clearly such a vigilance control will sooner or later apply the brakes. The this vigilance control system which is applied to reduce the drive load at Syria diesel multiple unit train is proposed.

KORAIL has been established by 1st January 2005. From organization change to KORAIL(Korea railroad Corporation), labour union and company management team has been argument for their train crews and drivers operation system. For example, train crew and driver working conditions; working hours per week, off day and duty day time, over night time working payment, current position payment, preparation time, company own lodge operation and so on. I assure that this comparison study for train crew and driver operation between KORAIL and EWS will helps to improve other korean railway companies management efficiency. In conclusion, EWS has 4$\sim$6 times more efficient employee for active operation than KORAIL per 1 freight brock-train operation. EWS has very resonable train crews and driver operation system, and self-control regulation for employee and management team with trusty. This thesis propose that korean railway companies and their own labour unions need joint research and benchmarking other oversea railway companies as like EWS.

This paper show Device Driver for RTOS-FT Systems. In this paper, a definition of Device Driver is introduced which is used in RTOS-FT Systems. The structure of Device Driver is briefly divided into physical layer and logical layer. The specific characteristic of Physical Held and logical field which is discussed in this paper is suggested for the system which is satisfied with fault-tolerant theory.

Driver's cab shall be designed ergonomically to provide the comfort for a driver to gather the information from the equipments and to operate the equipments effectively. The typical three design factors effected on the comfort are the access of driver's cab, freedom of movement inside the cabs and visibility condition. All control equipments shall be arranged so that those which are most often used or are of critical importance are the most convenient to the driver. The layout of driver's cab shall maximize the use of available space to be rugged and easily maintained. The visibility for the running direction along the track shall be secured. The visibility condition apply the seating position of the driver. Not only the environment condition(temperature, humidity, rattle, etc) but also the construction of driver's cab can be ergonomic design factor.

The design of driver's cab includes the structure of cab frame, the layout of driver's cab equipment and facilities, i.e. driver's desk, seat, windows, floor, interior equipment, cab partition etc. The concept applied to the detail design has to be based on the ergonomics to guarantee the safety, comfort, and easy operation for the driver. In the aspect of manufacture, one more factor 'modulization' has to be considered into the design of sub blocks for cost-down. The design has to be implemented in the space allocated for driver's cab, which space is directly determined by the cab frame, optimized for the layout of driver's cab. The design process and results of the driver's cab for KHST will be described in this paper.

Belief revision involves integrating new information with the current belief. It is a ubiquitous human activity. A critical feature of belief revision lies in its sequential nature. Railroad system can be described as organic. Engine drivers take a great role in this system. Recently, Hogarth and Einhorn(1992) have posited a belief-adjustment model for updating beliefs. Based on a sequential anchoring and adjustment strategy, the model is important for decision makers. The sequential nature of information processing is affected by some task variables. The purpose of this study is to examin factors which influnce on the Enginr Driver's belief revision process. The factors are the order, experience and task. The difference of belief revision is due to the order and experience level.

The research will be essential that the method for strengthening safety are safe installations in a hardware portion, a safe running ceremony of the vehicle employee (an engine driver) and the estimate of the situation which is accurate. In railway car the window wiper which is auxiliary equipment for safe operation is changed the existing manual control method with automatic correspondence precipitation used raindrops censor which can assure the vision of driving. It can be easy to safe driving as might have expected the object. We carried out studies technical review investigation which can accomplish the best suited wiping speed in maintaining an introduction existing system in the manual control system applied the existing train and corresponding to precipitation. The observation fact in the studies can be possible to ensure safety operation. That is, Manual operation method (of the driver) to add the automatic speed adjust function can operate improved window wiper drive system when it rains and, as was expected, it is able to ensure the range of a good railroad driver's vision and to concentrate in working at rainfall.

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.

Because a driver is located in the front end of KHST, he is most likely to be insured at collision accidents. So, it is very important to design some survival space for the driver. To evaluate the driver's safety of KHST (Korean High Speed Train), the front structure of power car is analysed using PAMCRASH under the SNCF accident scenario(collision against a movable rigid mass 15 ton at 110㎞/h). Because the driver's cab of KHST is a modified version of TGV-K, which is not so strong as to protect him, it turns out to be inadequate to guarantee his survival space. Therefore it is recommended to redesign the driver's cab in a crashworthy point of view like the case of TGV-Duplex or NEC.
