The Diyarbakir to Kayas route is serviced primarily by the regional train operated by TCDD, Turkey's state railway company. This train generally travels at speeds ranging from 80 km/h to 120 km/h (50 to 75 mph). The journey takes approximately 5 to 6 hours, depending on stops at various stations along the route.
The service features two classes of seating: standard and first class, allowing passengers to choose based on their budget and comfort preference. While the train offers basic amenities, such as refreshments and restrooms, it is designed to provide a reliable means of transportation between these two cities rather than speed. Overall, this train is a practical option for travelers looking to explore the region at a leisurely pace, without the high speeds associated with high-speed services.
