'''TCDD HT80000''' is a series of high-speed [[Engineering:Electric multiple unit|electric multiple unit]]s built by [[Company:Siemens|Siemens]] for the Turkish State Railways. The EMUs are used for the Yüksek Hızlı Tren (YHT) services on the Turkish high-speed railway network and especially on the Polatlı–Konya high-speed railway, where they can reach a maximum speed of 300&nbsp;km/h.<ref name=pdf>{{cite web|url=https://assets.new.siemens.com/siemens/assets/api/uuid:0e1ccf29-d0bf-468e-a9c6-2722aea68261/datasheet-velaro-tr-e.pdf|title=Velaro Turkey: High-Speed Train for TCDD|publisher=[[Company:Siemens Mobility|Siemens Mobility]]|access-date=2020-04-16}}</ref><ref name="SiemensVelaroTR">{{cite web|url=https://press.siemens.com/global/en/feature/velaro-turkey-high-speed-train|title=Velaro Turkey High-Speed Train|publisher=[[Company:Siemens Mobility|Siemens Mobility]]|access-date=2020-04-16}}</ref>

==History==
[[File:InnoTrans 2016 - TCDD HT 80000 - Siemens Velaro TR (2).jpg|thumb|left|180px|TCDD HT80105 (Velaro TR)]]
In 2013 TCDD concluded three contracts with [[Company:Siemens|Siemens]] for the acquisition of these seventeen units (1 unit for the first, 6 for the second and 10 for the last contract).<ref name=pdf/> Furthermore, Siemens would provide 7 years of maintenance and cleaning, and also provide a simulator.
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.<ref>{{cite web|url=https://railturkey.org/2014/11/11/high-speed-train-tender-cancelled/|title=Tender for HST Sets Cancelled. Now What?|website=Rail Turkey}}</ref> The bids for 10 high-speed train sets were repeated on 30 January 2017 with [[Company:Siemens|Siemens]] having proposed the Velaro TR again against [[Company:Alstom|Alstom]] and CAF.<ref>{{cite web|url=http://www.rayhaber.com/2017/02/tcddnin-10-adet-yuksek-hizli-tren-alimi-ihalesi-gerceklesti/|title = TCDD'nin 10 Adet Yüksek Hızlı Tren Alımı İhalesi Gerçekleşti|website=RayHaber|access-date=7 April 2017}}</ref>

In September 2013, the first set - a train originally intended for operation in {{wipe|Germany}} - was sent east for testing. Siemens also sent a Vectron MS demonstrator locomotive along with the [[Engineering:Siemens Velaro|Velaro]] train to [[Place:Turkey|Turkey]].<ref>{{cite web|url=http://www.railjournal.com/index.php/rolling-stock/first-siemens-velaro-en-route-to-turkey.html|title = First Siemens Velaro en route to Turkey|website=International Railway Journal|access-date=2 June 2015}}</ref> This first unit entered service on 23 May 2015 between Ankara and Konya.<ref name=2ndset/><ref name=TCDDVelaro>[https://railturkeytr.files.wordpress.com/2016/04/tcddvelarobyjeff.jpg TCDD's first Siemens Velaro train set at the Ankara Central Station] {{Webarchive|url=https://web.archive.org/web/20161013125028/https://railturkeytr.files.wordpress.com/2016/04/tcddvelarobyjeff.jpg |date=2016-10-13 }}</ref><ref>[http://www.tcdd.gov.tr/upload/Images/BannerImages/yolarkadas.jpg TCDD advertisement with Siemens Velaro]</ref> 
The second unit (but the first produced for TCDD) departed from Germany on 29 January 2016 and reached [[Place:Ankara|Ankara]] on 17 February 2016.<ref name=2ndset>{{cite web|url=http://www.tcdd.gov.tr/cok-yuksek-hizli-tren-setlerinin-ikincisi-geldi+h1362|title = Çok Yüksek Hızlı Tren Setlerinin İkincisi Geldi|website = TCDD|access-date=17 May 2016}}</ref> But the entry to service did not happen progressively and the 6 Velaro TR entered service on 10 March 2017.<ref>{{cite web|url=https://railturkey.org/2017/03/09/new-siemens-sets-on-service/|title = New Siemens sets on service|website=Rail Turkey|access-date=7 April 2017}}</ref>

===Accidents and incidents===
The unit HT80101 was involved in the Ankara train collision on 13 December 2018.<ref name=Aljazeera181213051334317>{{cite news |url=https://www.aljazeera.com/news/2018/12/turkey-train-crash-killed-high-speed-train-collision-181213051334317.html |title=Turkey train crash: Several killed in high-speed train collision |newspaper=Al Jazeera |access-date=13 December 2018}}</ref>

== Design ==
The train is based almost entirely on existing technology from the [[Engineering:Siemens Velaro|Siemens Velaro]] platform. Like most it is formed of one eight-car 200m set that can be coupled with another to produce a 16-car 400m set. Like other Velaros they can operate at temperatures between -25&nbsp;°C and 40&nbsp;°C. Most new technical features will also be used in all future Velaro trains.

=== Visual ===
A ''white - turquoise - grey'' colour scheme has been selected for the livery of the TCDD HT80000 high-speed train sets, instead of the traditional ''white - red - dark blue'' colour scheme used on the [[Engineering:TCDD HT65000|TCDD HT65000]] high-speed train sets. 

The appearance of the TCDD HT80000 is closer to that of the '2nd generation' [[Engineering:Siemens Velaro|Velaro]] trains (e.g. Eurostar E320) as opposed to the look of older [[Engineering:Siemens Velaro|Velaros]] like the ICE 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 older [[Engineering:Siemens Velaro|Velaro]] models. All electrical equipment is covered, that also enhances aerodynamics.

=== Technical ===
[[File:YHT train at Ankara railway station.jpg|thumb|left|TCDD HT80004 waits to depart the ATG terminal in Ankara]]

Each eight-car, 200m set has 32 [[Engineering:Axle|axle]]s, 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 with ETCS.<ref name=pdf/> Siemens gained data on aerodynamics from Germany, China, Spain and Russia. A high roof from the middle portion of the end car was introduced as it reduces sonic boom in tunnels, improves the driving friction and reduces exterior noise. Further aerodynamic improvements to the nose and spoiler means reduced CO<sub>2</sub> emissions of 14 g/passenger-km. In comparison, the average CO<sub>2</sub> emission of an aircraft with the same payload is 136 g/passenger-km.<ref name=pdf/>

As the first set was originally destined for DB, it differs from the rest of the series at some points. First, this set can reach a maximum speed of 320&nbsp;km/h contrary to 300&nbsp;km/h for the following sets. The electric system will also be different. While Velaro D can run under four different voltage systems (15 kV, 16,7&nbsp;Hz AC / 25 kV, 50&nbsp;Hz AC & 1.5 kV DC/ 3 kV DC), Velaro TR is a pure [[Engineering:25 kV AC railway electrification|25 kV, 50 Hz AC]] system vehicle. Finally, the interior and number of seats also varies.<ref>{{cite web|title=Here Comes New High Speed Train of Turkey|url=http://railturkey.org/2016/02/01/here-comes-new-high-speed-train-of-turkey/|website=Rail Turkey|access-date=3 February 2016}}</ref>

=== Interior ===

The first set has a total capacity of 460 places (333 in Economy class, 111 in First class and 16 for bistro).<ref>{{cite web|title=Siemens Velaro Started Service on Ankara-Konya Line|url=http://railturkey.org/2015/05/24/siemens-velaro-started-service/|website=Rail Turkey|access-date=4 February 2016}}</ref> The second set has a bit different configuration: 45 places in First class, 424 places in Economy class, 2 places for disabled passengers, a Business class with 3 compartments of 4 seats (12 places) and a bistro with 36 places for a total capacity of 519 places.<ref name=2ndset/> First class seats have also a personal media screen<ref>{{cite web|title=Here is the new luxury high speed train of Turkey|url=https://railturkey.org/2016/09/23/here-is-the-new-luxary-high-speed-train-of-turkey/|website=Rail Turkey|access-date=7 April 2017}}</ref> The rest of the series is expected to have the same capacity.
