The Kirikkale to Diyarbakir route is primarily served by regional rail services, with the most notable being the YHT (High-Speed Train) and the conventional train services. On this route, the YHT can operate at speeds up to 250 km/h (155 mph), making it a preferable choice for faster travel times. The journey typically takes around 7 hours, covering the distance with limited stops at major cities along the way.
In contrast, the standard train service takes a longer route, with travel times extending up to 10 hours, as it stops at more regional stations, making it suitable for travelers looking to reach smaller towns.
Both trains offer seating options that vary in comfort and pricing, allowing passengers to choose between economy and first-class services. The YHT trains are equipped with more modern amenities, focusing on speed and efficiency, while the conventional trains provide a more basic travel experience.
