On the Mihara to Osaka route, the main service available is the Sanyo Line operated by JR West. This line accommodates both local and rapid services, with the fastest rapid train known as the Special Rapid Service. The Special Rapid Service can reach speeds of up to 120 km/h (75 mph) and completes the journey in approximately 1 hour and 30 minutes, making stops at several key stations like Fukuyama and Nishin Takamatsu. In contrast, local trains take longer, around 2 hours, due to more frequent stops along the route.
While both options allow for easy access between Mihara and Osaka, the Special Rapid Service is better suited for those prioritizing travel time. Trains are equipped with comfortable seating, though amenities may be limited compared to higher-end services. Ideal travelers choose the rapid service for an efficient trip, while local train users might enjoy the scenery and opportunity to explore smaller towns along the way.
