The route from Demiriz to Sivas is primarily served by the regional trains, particularly the Vangölü Express. This service operates at speeds ranging from 80 km/h to 120 km/h (50 mph to 75 mph) and takes approximately 6 to 7 hours to complete the journey. The Vangölü Express is known for its comfortable seating and scenic views of the Turkish countryside, making it a pleasant travel option. Another service available is the Taşımacılık A.Ş. train, which also offers a similar travel time and speed. While the Vangölü Express focuses on providing a relaxing experience, the Taşımacılık A.Ş. trains may offer more frequent stops, making them suitable for passengers looking to visit smaller towns along the route. Both services do not include high-speed trains, as the infrastructure between these cities does not support faster train travel.
