The route from Koriyama to Hanamaki is serviced primarily by the Tohoku line, featuring two main train types: the Limited Express and Local trains. The Limited Express, known as the Rakuichi or Raku Raku, operates at speeds of up to 110 km/h (68 mph), completing the journey in approximately 50 minutes with fewer stops, making it suitable for travelers who prefer a faster option. In contrast, the Local trains make more frequent stops along the route, which can extend the travel time to around 1 hour and 30 minutes.
Both train types offer a variety of seating options, including standard and reserved seats, accommodating different preferences for comfort and budget. The Limited Express trains provide a more streamlined experience with more spacious seating areas, while the Local trains serve a more extensive set of stations, useful for passengers needing to reach destinations along the route. Overall, the choice between Limited Express and Local hinges on the desired balance between travel time and the number of stops.
