The World version of Rail Chase likely features adjustments to the original Japanese version, potentially including language localization and minor gameplay adjustments. It serves to make the game accessible to international markets.  Namco often released international versions to expand their reach globally.  Therefore, the core gameplay remains largely unchanged, maintaining the thrill of navigating the intense environments and shooting encounters as established by the original Japanese release.
