The route from Ueda to Kumagaya is primarily serviced by the Limited Express trains, specifically the Azusa and the Super Azusa services. These trains operate at speeds of approximately 120 km/h (75 mph) and cover the distance in about 2 hours, with several stops along the way. The Azusa service is designed for comfort, featuring spacious seating arrangements and onboard facilities that cater to travelers.

Both train types provide a variety of seating options, including both standard and reserved seating. Passengers can enjoy scenic views of the surrounding mountains and countryside during their travel. While not classified as high-speed trains like the Shinkansen, the Limited Express services offer a reliable and efficient way to travel between these two cities.
