TCDD HT80000, also known asSiemens Velaro TR, is a series ofhigh-speedelectric multiple units built bySiemens for theTurkish State Railways. The EMUs are used for theYüksek Hızlı Tren (YHT) services on theTurkish high-speed railway network and especially on thePolatlı–Konya high-speed railway, where they can reach a maximum speed of 300 km/h (186 mph).[1][2]

In 2013TCDD concluded three contracts withSiemens for the acquisition of these seventeen units (1 unit for the first, 6 for the second and 10 for the last contract).[1] Furthermore, Siemens would provide 7 years of maintenance and cleaning, and also provide asimulator.But in the end of 2014, the third contract on the last 10 sets was canceled by the Public Tender Committee of Turkey because of a missing certificate.[3] The bids for 10 high-speed train sets were repeated on 30 January 2017 withSiemens having proposed the Velaro TR again againstAlstom andCAF.[4]
In September 2013, the first set - a train originally intended for operation inGermany - was sent east for testing. Siemens also sent aVectron MS demonstrator locomotive along with theVelaro train toTurkey.[5] This first unit entered service on 23 May 2015 betweenAnkara and Konya.[6][7][8] The second unit (but the first produced forTCDD) departed from Germany on 29 January 2016 and reachedAnkara on 17 February 2016.[6] But the entry to service did not happen progressively and the 6 Velaro TR entered service on 10 March 2017.[9]
The unit HT80101 was involved in theAnkara train collision on 13 December 2018.[10]
The Velaro TR is based almost entirely on existing technology from theSiemens Velaro platform. Like most, it is formed of one eight-car 200 m (656 ft 2 in) set that can be coupled with another to produce a 16-car 400 m (1,312 ft 4 in) set. Like other Velaros, the Velaro TR can operate at temperatures between −25–40 °C (−13–104 °F). Most new technical features will also be used in all future Velaro trains.
Awhite - turquoise - grey colour scheme has been selected for the livery of the TCDD HT80000 high-speed train sets, instead of the traditionalwhite - red - dark blue colour scheme used on theTCDD HT65000 high-speed train sets.
The appearance of the TCDD HT80000 is closer to that of the '2nd generation'Velaro trains (e.g.Eurostar E320) as opposed to the look of olderVelaros like theICE 3M, that have the lights closer to the coupler, as opposed to the newer position against the windscreen surrounds, although if you look more closely this is the fourth stage of evolution which can be seen on the outside with the new Velaro. The door windows are larger, square windows, as opposed to the airplane style oval windows on olderVelaro models. All electrical equipment is covered, that also enhances aerodynamics.
Each eight-car, 200 m (656 ft 2 in) set has 32axles, of which 16 are driven. This gives the following wheel arrangement:
Bo’Bo’+2’2’+Bo’Bo’+2’2’+2’2’+Bo’Bo’+2’2’+Bo’Bo’
All trains are fitted withETCS.[1] Siemens gained data onaerodynamics from Germany, China, Spain and Russia. A high roof from the middle portion of the end car was introduced, as it reducessonic boom in tunnels, improves the driving friction and reduces exterior noise. Further aerodynamic improvements to the nose and spoiler means reduced CO2 emissions of 14 g/passenger-km. In comparison, the average CO2 emission of an aircraft with the same payload is 136 g/passenger-km.[1]
As the first set (HT80001) is aVelaro D which was built according toDeutsche Bahn specifications, it differs from the rest of the trains (Velaro TR) at some points. The first set (Velaro D) can reach a maximum speed of 320 km/h (199 mph) contrary to 300 km/h (186 mph) for the following sets (Velaro TR). Their electric systems are also different: While the Velaro D can run under four different voltage systems (15 kV, 16,7 Hz AC / 25 kV, 50 Hz AC & 1.5 kV DC/ 3 kV DC), the Velaro TR is a pure25 kV, 50 Hz AC system vehicle. Finally, their interior and number of seats are also different.[11]

The first set (Velaro D) has a total capacity of 460 places (333 seats in Economy class, 111 seats in First class, and a bistro with 16 seats).[12] The following sets (Velaro TR) have a different configuration: 45 seats in First class, 424 seats in Economy class, 2 seats for disabled passengers, a Business class with 3 compartments of 4 seats (12 seats in total), and a bistro with 36 seats, for a total capacity of 519 places.[6] First class seats have a personal media screen.[13]
