Abstract

This study explores whether urban rail modes differ in operating cost. It does so by estimating a Trans-log Cost Function based on data from 46 Japanese urban rail companies from 2004 to 2015. Our findings from this study indicate that over-ground, monorail, and under-ground in Japan differ in returns to density (RTD) and returns to scale (RTS). With this understanding, we believe that the policymakers, regulators and stakeholders will be able to make more informed decisions on policies, regulations and future investments pertaining to urban rail services. For a more conclusive understanding on operating cost differences between urban rail modes, we suggest this empirical research be replicated in other regions where data are sufficient.
