To improve the railway transportation capacity and maximize the benefits of railway transportation, a method for layout optimization of railway transportation route based on deep convolution neural network is proposed in this study. Considering the transportation cost of railway transportation and other factors, the layout model of railway transportation route is constructed. Based on improved ant colony algorithm, the layout model of railway transportation route was optimized, and multiple candidate railway transportation routes were output. Taking into account external information such as regional information, weather conditions and actual information of railway transportation routes, optimization of the candidate railway transportation routes obtained by the improved ant colony algorithm was performed based on deep convolution neural network, and the optimal railway transportation routes were output, and finally layout optimization of railway transportation routes was realized. The experimental results show that the proposed method can obtain the optimal railway transportation route, the shortest transportation length, and the least transportation time, maximizing the interests of railway transportation enterprises.

A route control in railway is one of the very important system to operate a train. An efficient train route control assures to increase train operation performance with a same railway system. The erroneous route control can accompany serious accidents which occur train collision or derailment which provokes death. A Route control carries out exactly lest the accident should take place. An interlocking table is widely used for the exact route control. The table has the problem of its exactness proving because it has been established by experts. In this paper, We tried to formalize a route control using mathematical logic. A route consists of symbolized tracks, signals, switch and crossing. It represents as a set, respectively. We proposed route setting control logic, converted the elements to set logics and construct route logics with the set logics of the elements. Finally we proposed a model which presents a prototype routes and we proved the proposed logics using the proposed method.

TSR (Trans-Siberian Railway) route is losing price competitiveness versus Deep Sea route in the transportation from East Asia to Europe, including Moscow. To further attracting the containers to the TSR route, it will be necessary (1) to keep competitive through rate, linked to fluctuating Deep Sea rate; (2) to strengthen speed advantage; (3) to enforce seamless transportation system, including simplified customs clearance procedures. In transportation to Central Asia from East Asia (Korea and Japan), TSR is competitive versus TCR (Trans-China Railway), depending on destinations. Korea has been the leader in revitalizing the TSR route since 2000. Key contributors were affluent export containers to Russia and Central Asia, port of Busan, efficient maritime transport network to Far East Russia, and Korean forwarders' persistent efforts for activating the market. Korea and Japan have a possibility of cooperation in using the TSR route efficiently, such as organizing a joint block train to a same destination.

The alignment design is one of the most influencing elements in earth work for the railway design. The amount of earth work mostly depends on the route, and the construction cost for railway construction largely depends on it. For this reason. it is necessary to develop a program for the construction cost estimation by route alternatives. This study introduces a program for the estimation of the earth work amount including the logics and the way to use.

Optimal route selection of railway should take consideration of the function of the railway, topography, practicability of construction and management as well as the cost. This study performed the surveys for experts and surrounding industries and the review for the bid guidelines in order to develop the quality model with the AHP method and establish the weight for each factor. Six quality models were developed for such as the efficiency of railway operation, structure design and practicability, economic feasibility, correspondence with other plans, civil appeal and environmental sustainability, and correspondence with system. The detailed evaluation elements were also derived by each factors.

This study is to develop the model of alignment optimization based on design criteria by approaching through alignment of railway design and problems in economy, environment and technology for satisfying traffic volume of the main roads caused by economical and social developments. Now, Geographic Information System isn't applied when designing a present railway in home. And the design of railway alignment is still set on importance of transition curves and cant according to passenger comfort in abroad so tile study of railway alignment is at initiation phase so far. This paper is about decision of optimal alignment between two stations such as starting point and ending point automatically using GIS in optimization of railway alignment. A route between Sungsan city and Shinpung city is the training area and the study compared and evaluated optimal railway route by GIS automatically with present railway route designed. Present optimal fomulas was used in this study for optimization of railway alignment. The model of optimization of railway alignment was developed through topographical elements and it was mentioned by the model of road alignment because of the similarity in design of alignment. But the design of lateral track irregularities, cant fur passenger comfort and motion sickness fellowed by train rolling have to be considered more. Anyway, this study farmed the basis of using GIS and the study should be keep going on in the future.

In this paper, an electrical power simulation program was developed to predict the energy consumption of the electrical railway propulsion system, which considered the actual operating conditions of the electric railway vehicles. The developed program was designed to predictable the energy consumption during a virtual driving in the actual route of the virtual railway vehicles equipped with a propulsion system consisting of power conversion equipments and traction motors. In addition, the accuracy verification of the electrical power simulation program for a propulsion system was performed by using a real power consumption data, which was measured during the driving of the railway vehicles in the Gyeongui Line. In conclusion, the electrical power simulation program for a propulsion system was validated throughout a comparative investigation between the simulated values and the experimental values and the energy consumption characteristics of electric railway vehicles on the existing route or the new route will be possible to predict throughout the virtual simulation considering the driving conditions of the electric railway vehicles.

The improvement of the situation on the Korean Peninsula, following the June 2000 Summit, has opened up the possibility of reconstructing the railway between the North and the South. The interconnection of the railway systems would allow cargo transportation from the south of the Korean Peninsula to Russia, China and Europe. This could open up a faster and more economical cargo transportation route than the all-water route.(omitted)

Serving a function of transportation information and geographic information together with proper composition of design elements, railway route maps have to be designed to easily recognized to the concerning passengers as they offer users to access to the guide information. This study analyzed visual aspects of the maps of 8 underground routes linking Seoul and urban cities(D1 - D8) and the maps of 8 different cities overseas (A1 - A8). As a source of information with condition of easy recognition, universality and aesthetics, route maps should be designed and consistently managed by the manual which establishes the principle of the logical system and the standardized form.
