Infrastructure condition indicators: trends vs absolutes

The frequency of broken rails, track misalignments, rail defects, track geometry irregularities, structural defects and failures in signalling and electrical systems are often used as indicators of the condition and operational performance of rail networks. An operator's assessment of whether systems are improving, remaining steady or deteriorating is typically based on the analysis of trends in these indicators. While trends are important they give no indication to the operator of how the condition or operational performance of the rail network compares with either 'industry norms' or results being achieved by others. The purpose of this study is to demonstrate that it is possible to compare condition and operational performance indicators between operators. This is achieved by 'normalising' the raw counts of network failures.
