On the route from Karaisalibucai to Mersin, passengers can travel on the regional trains provided by TCDD (Turkish State Railways). The primary service on this route is the DMU train, which typically operates at speeds ranging from 80 to 120 km/h (50 to 75 mph). This journey of approximately 140 kilometers (87 miles) takes about 2 to 2.5 hours, depending on the specific schedule and stops made along the way. The DMU trains provide standard seating and basic amenities for passengers, including luggage racks and restrooms. While not as fast as high-speed trains found on other routes in Turkey, such as the Ankara to Istanbul High-Speed Train, the regional service is essential for connecting smaller towns to the more significant urban centers. Travelers should expect a few stops along the route, which may include small towns and key stations where passengers can board or disembark. Although the train's speed and travel time are more modest, it offers a direct and straightforward way to reach Mersin.
