| dc.description.abstract | Rail infrastructure is a large and costly investment, therefore infrastructure managers should manage the infrastructures properly to achieve the aim of the project. Ones the railway line is constructed it should be managed efficiently. In order to have an efficiently management system the infrastructure manager should know all cost during railways life time. Life cycle cost analysis help the infrastructure manager to know the cost of maintenance, risk, renewal, organization, Train delay and initial cost. The aim of this research is to analyze the Life cycle cost of Addis Ababa – Djibouti Railway track. In this research rail, Sleeper and ballast LCC models are developed separately. For the rail and Sleeper LCC model, an existing model is used, whereas for the ballast LCC model, a new model is proposed based on a track geometry degradation model. This paper also describes a decision support system approach for railway track maintenance and renewal management system to analyze the track components and suggests methods for helping the track managers and help engineers decide when maintenance is necessary and when is the best time for renewal. In this Thesis, the Life cycle cost of the track is determined and the results shows that the maintenance cost of rail using lubrication has less LCC than without use lubrication. The analysis also shows the best Grinding interval, Inspection interval, Tamping interval and Renewal interval which give the least LCC of the line. | en_US |
