  • The automatic/driverless operation which are great important techniques in metro railway are required to increase higher safety, greater reliability, and transport capacity. To satisfy such demands, we must have the system design and testing technique for the railway system operation. These techniques are related to the onboard train control and communication systems which include TCMS(Train Control and Monitoring System), ATO(Automatic Train Operation), ATC(Automatic Train Control), and TWC(Train to Wayside Communication). These sub-systems must be interfacing with not only each others but also the signal system on the ground. We tested the train control system on Test line that has been developed on the basis of the standardized type EMU for korea railway systems. This test line which is located in Sangju, have been constructed for testing 7 & 8 line of Seoul Metro railway.

  • The train automatic operation control system is an on-board train control system that is widely adopted in modern rapid transit systems. The control system consists of TCMS(Train Control and Monitoring System), ATC(Automatic Train Control), ATO(Automatic Train Operation) and TWC(Train to wayside communication) in the train and wayside facilities. The functions of the system is to regulate train riding comfort, to service limited speed and smoothness during start, acceleration, constant speed travel, and fixed point parking under the corresponding commands. The paper describes the simulation model of the train automatic operation control of subway system, configuration of simulator hardware and software and operational algorithms.

  • Automatic Train Stop (ATS) is a device that automatically stops or decelerates a train when the train exceeds the permitted speed limits or violates the signal regulations. The railway signaling system has been evolved to an automatic train control system (ATC), and is being developed into Distance-to-Go and Communication Based on Train Control (CBTC). In spite of that, the ATS system is currently being operated in Seoul Metro (line 1 and 2) and most of railway lines in Korea as well as overseas. In this study, we presents the technical methodology to prevent human errors in order to secure the safety in operation of the ATS system.

  • An automatic operation of train is executed by an automatic train operation(ATO) system. The main function of ATO system is to control train speed. So it makes the train stop at the programmed position accurately and improve riding comfort. In this paper, A fuzzy control is designed for speed control. The simulation is executed for verifying the speed control performance of the fuzzy system and comparing with that of the conventional PI.

  • The present headway on KNR(Korea National Railway) lines varies from 6 to 10 minutes depending on the each line and by the operation of High Speed line in 2004, the bottleneck would be expected within a few sections such as Daejeon-Daejeon shunting yard which will be the common mute between KTX(Korea Train Express) and conventional trains. Therefore, KNR would like to reduce the headway of the all lines by 4 minutes with the implementation of ERTMS/ETCS on-board system. Where ETCS(European Train Control system), the subsystem of ERTMS, is Automatic Train Protection system for safety train running. This study will be analyze expected braking distance and running time depending on characteristics of conventional passenger and freight trains and high speed train will be operated within electrified conventional line for comparing the headways of ATS(Automatic Train Stop) system and ETRMS/ETCS system within the Daejeon-Daejeon shunting yard section.

  • The automatic-driverless operation, a very important technique for metro railways, is necessary for achieving higher safety, greater reliability, and bigger transport capacity. To achieve these things, we have to build up the system design and tasting techniques for the railway system operation. These techniques are related to the onboard train control and communication systems which include TCMS(Train Control and Monitoring System), ATO(automatic train Operation), ATC(Automatic train Control), and TWC(Train to wayside communication). These sub-systems should interface not only with each other but also between the sub-systems and the signal system on the ground. For the saving of energy, we designed coasting strategy of ATO system, In this paper, we developed ATO system and tested on the test line and ...

  • The ATO(Automatic Train Operation) System is used for train operation instead of drivers. It is interfaced with TCMS(Train Control and Monitoring System) and ATC/TWC system in the train and wayside facilities. In this paper describes configuration of ATO, specification of ATO hardware, construction of ATO software and the algorithm fur automatic train speed regulation in the carborn ATO system. ATO Application Software is consist of ART, SPR, REG, SRV and PSM tasks. ART task is main control part of the ATO that determine ATO control, ATO mode, state transition. SPR determine speed reference according to train motion status, track data, train data and restricted train speed. REG task regulated train speed form the starting of one station to the precision stop at the other station under the result of ART and SPR tasks. In this paper, a algorithm for the train speed regulation while running is described.

  • The Wolmi Eunha-Rail in Incheon is connecting Wolmido and Incheon Station with an elevated monorail road supported by piers. This railroad system is characterized by driverless automatic operation and moving-block based control. The main technology applied to this signal-controlled system is CBTC (Communications-Based Train Control) which based on wireless communications. The CBTC system is simple in that composition so that can minimize field facilities and lowers costs of construction and maintenance. This CBTC system is emerging as a major signal-controlled system in the future metro market.
