ANALYSIS OF THE PROFITABILITY RESULTING FROM THE INTRODUCTION OF IMPULSE STARTING IN TRACTION COMPLEXES OF THE POLISH RAILROAD SYSTEM

ANALIZA OPLACALNOCCI WPROWADZENIA ROZRUCHU IMPULSOWEGO W ZESPOLACH TRAKCYJNYCH PKP

Changes of operational parameters of the suburban rolling stock resulting from the introduction of SCR impulse starting equipment to replace resistance starting are analyzed. The effect of these changes on running costs is discussed under consideration of the changes appearing in the supply system. The notion of the modernization profitability index is introduced. It results from the comparison of the effectiveness indices of two comparable systems and makes it possible to determine the limit values of the modernization costs. As an example, the results of calculation for the suburban Polish Railroad rolling stock are given.
