The article presents an assessment of the efficiency of modernizing the SM series diesel locomotive based on LCC analysis. The analysis aimed to determine measurable economic effects expressed in costs generated by the modernized locomotive compared to a non-modernized locomotive over a 25-year service life.1. INTRODUCTION
Among the initiatives aimed at increasing the efficiency of rail transport, actions to reduce the operating and maintenance costs of traction vehicles play a significant role. A way to achieve this goal is the modernization of diesel locomotives, which additionally takes into account conditions regarding exhaust emissions and noise. The basic assumptions for locomotive modernization are [1, 2]:
− improvement of operational efficiency by reducing fuel and consumable consumption, − increasing intervals between repairs, − adapting technical and operational parameters to the requirements of international regulations, − improving environmental impact indicators, − improving the working conditions of the locomotive driver, − introduction of modern control systems.
In recent years, there has been great interest from rail carriers in the modernization of diesel locomotives. They have been carried out or are in progress (…)
