Turkey’s High-Speed Train Revolution: The YHT Network and Future Ambitions
Over the past two decades, Turkey has transformed its rail system with a rapidly expanding high-speed train (Yüksek Hızlı Tren, or YHT) network. These trains connect major cities, dramatically reduce travel times and represent the country’s ambitions for modern, efficient transportation. Below is an in-depth look at the high-speed network: its history, key routes, trains, current developments and future plans.
Origins and Early Development
Turkey’s journey into high-speed rail began in the early 2000s as part of a nationwide effort to modernise railway infrastructure. The first major YHT line opened in March 2009 between Ankara and Eskişehir, reducing a four-hour journey to around 1.5 hours. This marked the start of a rapid expansion programme.
In 2011, the Polatlı–Konya high-speed section entered service, connecting Polatlı (near Ankara) to the city of Konya. Two years later, the Konya–Eskişehir connection was completed.
A significant milestone came in 2014 with the opening of the Ankara–Istanbul high-speed line, followed shortly by direct Konya–Istanbul services. In April 2023, the network expanded further east with the opening of the Ankara–Sivas high-speed line.
Key High-Speed Lines and Performance
Ankara – Eskişehir
This was Turkey’s first high-speed corridor. Trains reach speeds of up to 250 km/h, cutting travel time to about 1 hour 30 minutes.
Polatlı – Konya
Opened in 2011, this 212 km line operates at up to 250 km/h and supports services between Ankara, Konya and Istanbul.
Ankara – Istanbul
One of the busiest routes, this line links the capital with Turkey’s largest city. Several sections are designed for speeds up to 250 km/h, and multiple services operate daily.
Istanbul – Konya / Karaman
YHT services run from Istanbul through Ankara or Polatlı towards Konya, extending further to Karaman with a section opened in 2022. Trains on this route regularly exceed 200 km/h.
Ankara – Sivas
Launched in 2023, this important eastern extension significantly increases the reach of the high-speed network.
The Rolling Stock: Trains on the YHT Network
Turkey operates two main types of high-speed trainsets:
- TCDD HT65000:
Built by CAF in Spain, these six-car sets run at speeds up to 250 km/h and carry roughly 419 passengers. - TCDD HT80000 (Velaro TR):
Manufactured by Siemens, these eight-car trainsets can carry around 450 passengers. Although capable of speeds close to 300 km/h, they typically operate at lower speeds depending on line limits.
Usage, Ridership and Impact
Since its launch, the YHT network has carried more than 100 million passengers. The Ankara–Istanbul line is the busiest, with tens of millions of journeys recorded.
When combined with feeder services and conventional rail, the YHT system serves about half of Turkey’s population. Ongoing construction aims to expand the total length of high-speed and rapid rail lines—currently over 2,000 km—to more than 4,000 km within the next few years.
Future Plans & Indigenous High-Speed Train Projects
Turkey is developing ambitious new projects, including a proposed super-high-speed line between Ankara and Istanbul, designed for speeds of up to 350 km/h, potentially reducing travel time to around 80 minutes.
International connections are also in progress, including the Halkalı–Kapıkule high-speed line towards the Bulgarian border. Within Turkey, new corridors such as Sivas–Erzincan are in planning, designed for speeds up to 250 km/h.
Turkey is additionally investing in domestically produced electric multiple units through TÜRASAŞ, aiming to become self-sufficient in manufacturing high-speed and rapid-speed trainsets.
Strategic Significance
The YHT network has become a cornerstone of Turkey’s modern transportation system. It improves mobility between major cities, reduces highway congestion, lowers carbon emissions and supports regional economic development. As the network expands, it strengthens Turkey’s role as a bridge between Europe and Asia.
A Reflection: Britain vs. Turkey
It is striking to compare Turkey’s rapid progress with the much slower development of high-speed rail in the United Kingdom. While Turkish cities are now linked by fast, reliable rail services, the UK continues to struggle with delays, cancellations and political disputes over long-term projects like HS2. Turkey’s achievements show what can be accomplished with clear planning, sustained investment and a commitment to modernising the country’s transport future.
