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.
