Synthesis of railway infrastructure [PDF]
WIT Transactions on The Built Environment, 2010 This paper addresses the problem of generating a cost-optimal railway infrastructure by stating and solving a linear optimization problem. Railway infrastructure is represented by a network consisting of nodes and arcs. The nodes represent stations; the arcs lines connecting the stations.

A Review of NDT Methods for Wheel Burn Detection on Rails
Sensors, 2023 Wheel burn can affect the wheel–rail contact state and ride quality. With long-term operation, it can cause rail head spalling or transverse cracking, which will lead to rail breakage.

Heuristics for railway infrastructure saturation
Electronic Notes in Theoretical Computer Science, 2001 AbstractThis research concerns the problem of the evaluation of the railway infrastructure capacity. It is an important question when railway authorities have to choose between different infrastructure investment projects. We developped independently two heuristic approaches to solve the infrastructure saturation problem.

Optimising Indian Railways Infrastructure by AI
Journal of Mobile Multimedia, 2021 The pressure on the Indian railway (IR) networks has increased due to higher demand for mobility and growth in India’s population over past several decades. In order to meet the higher demand, IR has put priority in capacity building by increasing the number of coaches per train, running more trains, and building more tracks.

Safety and risk analysis at railway crossings of north-south Addis Ababa light rail [PDF]
Smart and Resilient Transportation, 2021 Purpose – Railway-level crossings (RLCs) are the point of intersection between rail and road users and are therefore hotpots of road-rail user conflict and catastrophic collisions. The purpose of this study is to assess the risks associated with RLCs and

Detection of Rail Defects Using NDT Methods
Sensors, 2023 The rapid development of high-speed and heavy-haul railways caused rapid rail defects and sudden failure. This requires more advanced rail inspection, i.e., real-time accurate identification and evaluation for rail defects. However, existing applications

Research of geometric parameters of symmetric railroad switches [PDF]
MATEC Web of ConferencesTurnouts are a barrier in the track for setting the permissible speeds of trains movements on the main tracks, as they have special structural devices for branching traffic from the main track to the side one.
