Traveling from Karuizawa to Tsuruga, passengers can choose between two train services: the Limited Express Shinano and the Standard Express. The Limited Express Shinano operates at speeds of up to 120 km/h (75 mph) and completes the journey in approximately 3 hours 20 minutes, making fewer stops and providing a direct route to Tsuruga. On the other hand, the Standard Express takes a bit longer, around 4 hours, as it stops at several regional stations, allowing for more access to local areas along the route.
Both services feature reserved seating and have amenities such as food and drink options available on board. The Limited Express Shinano is better suited for those prioritizing travel speed, while the Standard Express may be attractive for passengers looking to explore additional stops along the way.
