“…We previously proposed a concept for a cost-effective communication-based train control (CBTC) system that provides train separation and route control functions without trackside central controllers and signal lines and presented its fundamental principle, i.e. ring topology information sharing among onboard and switch controllers (13) . We have now conducted a feasibility study of the proposed system.…”

Conventional communication-based train control (CBTC) systems enable the frequent operation of trains by detecting train's position and the telecommunication system between the onboard and trackside controllers compared to traditional signalling systems. However, the railway signalling system is still costly, and the cost of the trackside central controllers is particularly high because high-performance failsafe hardware and software are required to control the many pieces of field equipment. Given this situation, we have proposed a concept for a cost-effective CBTC system that provides functionalities equivalent to those of existing signalling systems by using ring topology information shared among the onboard and switch controllers without trackside central controllers. Its basic mechanism is the circulation of a telegram containing information about the exclusive rights to virtual blocks in turn among the controllers within each controlled section. This mechanism reduces the equipment cost to approximately one-third that of a conventional CBTC system. We have now conducted a feasibility study to verify the practicality of this system and have identified potential problems related to system reliability and transportation capacity. This paper presents solutions to these problems and experimental results to show that the proposed system is technically valid and can be applied to many railway lines.

Train speed control is a vital part of train protection to build safe movement at an operation track. There is a special condition of track that needs more attention to protect the train, for example in slope area. Moreover, in developing country with vandalism problem, it requires to install minimalized equipment on the trackside. In addition, in tropical country, on tracksides it will be potentially pooling water that influences to the performance of trackside equipment. To address these problems, we propose the train speed control for slope area using infrared system. By installing on the pole configuration, the system offers a less challenging, economically sensible, minimalized installation of equipment on the trackside and reliability for heavy rain environment. This paper concentrates on the controlling train speed and measurement performance evaluation in slope area. The proposed train speed control system can monitor and control the speed in sloping area with maximum 3.6% and controlled speed about 20 km per h.
