This study aims to investigate the effects of the centralized allocation and optimization of Taiwan’s railway resources (personnel and equipment) on the overall operational efficiency of its railway industry, based on the concept of two-phase centralized allocation and reallocation of resources. A Taiwan railway data analysis conducted in 2011 showed that the high overall output due to the effi...

The project named “the rescue system and key technology of high-speed railway in perilous mountains” primarily focuses on current railway constructions and operations in China. To state the relationship between risk events and risk factors, we classified the risk sources of operating tunnels of high-speed railway in perilous and mountainous area and established a hierarchical assessment system ...

In this paper, analysis for reducing lateral forces is implemented by using a railway vehicle model on a sharp curved track. Also, in order to minimize some problems when a railway vehicle runs on a sharp curved track, an active-steering bogie system is investigated. An active steering bogie system of a railway vehicle is designed to alleviate contact forces and to decrease wear of wheel/rail i...

In this paper we present a verification strategy for signalling principles for the control of a railway interlocking system written in ladder logic. All translation steps have been implemented and tested on a real-world example of a railway interlocking system. The steps in this translation are as follows: 1. The development of a mathematical model of a railway interlocking system and the trans...

In this project the verification of safety conditions for the control of a railway interlocking system written in ladder logic is carried out. All translation steps have been implemented and tested for a real-world example of a railway interlocking system. The steps in this translation are as follows: 1. The development of a mathematical model of a railway interlocking system and the translatio...

Introduction Providing more comfortable station environment foremost from the customer’s point of view is essential for sustaining railway customers. As the result of surveys regarding comfort and cleanliness of railway stations and airports, approximately 90% of customers answered that airports are more comfortable and cleaner than railway stations (Fig. 1). Customers also have shown a keen in...

Historically, changes in transport infrastructures have produced a progressive contraction of space, in the sense that travel times have been shortened and transport costs have been reduced. Improvement of transportation networks reduces interaction costs, increases the overall competitiveness of the system and allows for more specialization such that economies of scale and specialization benef...

SAR differential interferometry is an innovative space-based measurement technology for ground deformation. Under inclement Qinghai-Tibet plateau environment, monitoring and analysis of railway subgrade deformation using satellite interferometry in plateau permafrost region has very important engineering significance for stability evaluation and safety management. In the paper, a brief descript...
