New railway legislation in Sweden has increased the need for transparent access charges on the Swedish railway network. We estimate cost functions for infrastructure operation, maintenance and renewal in the Swedish national railway network, using unobserved effects models and calculate marginal costs for railway infrastructure wear and tear. We find evidence of unobserved fixed effects at a tr...

Railway capacity is not only the basic condition for the allocation of railway resources but also an index set for the evaluation of the usage of them. Sometimes the maximum theoretical results calculated according to the coefficient methodology for the capacity calculation of the Existed Chinese traditional railway (abbreviated as ECTR) would be less than those statistical results from the rea...

The economy of China and the travel needs of its citizens depend significantly on the continuous and reliable services provided by its railway system. However, this system is subject to frequent natural hazards, such as floods, earthquakes, and debris flow. A mechanism to assess the railway system vulnerability under these hazards and the design of effective vulnerability mitigation strategies ...

A railway interlocking system (RIS) plays a vital role in the safe transportation of a railway system. It is responsible for the safe routes of trains making sure that each train movement follows the other in a proper and safe sequence. Detailed verifications and evaluations are mandatory before deploying an RIS, since it is a safety critical system (SCS). But the increasing complexity of the R...

China Railway consists of eighteen regional bureaus, geographically distributed across China, with each regional bureau having their own regional Data Center. Physically distributed and managed at a regional level, the information system of China Railway is a highly complex distributed mission critical system, integrated in networks but largely isolated in term of system resources with applicat...

The performance of railway operations depends highly on the quality of the railway timetable. In particular for dense railway networks it can be a challenge to obtain a stable robust conflict-free and energy-efficient timetable with acceptable infrastructure occupation and short travel times. This paper presents a performance-based railway timetabling framework using an integrated approach on t...

Railway capacity has been a significant issue in the railway industry. Over the last few years, numerous approaches and tools have been developed to compute railway capacity. In this paper, we compute railway capacity to design a topological model for solving periodic train scheduling, developed in collaboration with the National Network of Spanish Railways (RENFE). This topological technique t...
