The train service from Pinarli to Diyarbakir is predominantly operated by the YHT (High Speed Train), which provides a comfortable travel experience between these two locations. The YHT trains are known for their efficient service and modern amenities. Traveling at speeds of up to 250 km/h (155 mph), the journey typically takes approximately 6 to 7 hours, depending on the specific service chosen and the number of stops along the route. On the other hand, the slower Regional train services may also be available, offering a different travel experience with slightly longer durations but often at a lower ticket price. These regional trains usually operate at speeds of around 100-160 km/h (62-99 mph) and provide access to additional smaller stations along the route. For travelers who prioritize speed and comfort, the YHT is the preferable option, while those looking to explore more regional stations may find the Regional train more suitable.
