New approach to maintenance based on functional analysis of traction engines: Case of Locomotives of the International African Transport Company by RAIL

Abstract

This document shows the difficulties encountered by railway companies in the operation of locomotives. He makes a special mention in the case of International African Transport Company by RAIL. To do this, the history of International African Transport Company by RAIL locomotive operating failures has allowed us to calculate their operational availability, their mean times of failure,2wsa3ewdcxe3rtf2wsa3ewdcxe3rtf6 and their average technical repair times. The analysis shows that out of twenty locomotives, 60 percent has an operational availability below the 95 percent reference value. Using the functional analysis method, the locomotive operating indicators are evaluated and represented in Operation Functional Specification showing the deficiencies and achievements. Ishikawa has also been used on the traction motor, the element at the origin of the unavailability of locomotives, to identify the major causes, allowing making proposals for solutions, to improve the operational availability of traction engines and, in turn, of locomotives.
