This study examines the rail spare ratios for all heavy and commuter rail systems over a seven year-span, 1985 to 1991. In accordance with the Section 15 Glossary of Transit Terms, this study will reference Rapid Rail as "Heavy Rail". The actual annual spare ratio percentages are appended. This study is stratified into two major sections for analysis purposes, they are current developments and systems size analysis. The current development analysis specifically examines Section 15 data for heavy and commuter rail systems for the 1991 report year. The system size analysis examines heavy and commuter rail systems according to systems size. Heavy rail systems are divided into three categories those agencies operating a Total Active Fleet (TAF) of over 500; 200 - 499 TAF; and under 200 TAF. Commuter rail systems unlike heavy rail operate less vehicles in maximum service nationally. Thus, commuter rail systems were divided into three categories that differ fi-om the heavy rail categories, they are over 350 TAF; 100-350 TAF; and under 99 TAF.
