This series was ordered in two batches of ten and two trains. They are being financed via a foreign loan over 22 years, with a seven-year grace period. Later, 4 more sets came to Turkey in 2008, 3 more in 2009 and 2 more in 2010. On 13 March 2009, the inaugural ceremony took place in
Ankara; attended by President
Abdullah Gül, Prime Minister
Tayyip Erdoğan, and Minister of Transport
Binali Yıldırım, who started the
YHT service with one of these sets. Subsequently, 2 additional sets were ordered with the same characteristics, reaching a total of twelve HT65000 trains. On 13 November 2009, the HT65006 derailed and became temporarily unusable after an accident (without injuries or fatalities) at Hasanbey near
Eskişehir while it was passing from the high-speed line to the classical line. ==Design==
