Tüvasaş will build 111 cars initially, with between three and six cars per train. The first train is due to be completed by the end of 2019. Eventually, Tüvasaş hopes to produce another 333 cars for TCDD, and export the trains as they are designed to meet the European Union’s Technical Standards for Interoperability (TSI). These are the first aluminium-bodied trains to be produced by Tüvasaş and a new building will be completed in June at Tüvasaş’ existing site at Sakarya to manufacture the trains. The trains, which are intended for inter-city services, will have a maximum speed of 160km/h and will have one motor and one trailer bogie per car. A five-car set will have one first-class coach, four second-class coaches with a buffet counter, and a total of 322 seats. There will be two seats for disabled passengers and a toilet for their use.
