TCDD E44000, also referred to as the "National Electric Train" () by the media, is a model of electric trainset produced by TÃÂVASAà  (now under TÃÂRASAà Â) for TCDD Taà Âñmacñlñk. Trains started to be delivered to the Turkish State Railways (TCDD) on 27 April 2023.
The first unit produced for TCDD Transport was delivered to the Adapazarñ train station on 27 April 2023. After being exhibited at various stations in Istanbul in May, the train made its inaugural journey on May 27 along the Adapazarñ-Gebze line. TÃÂRASAà  plans to export E44000 units to European Union countries in the following years.

There are currently 3 sets in existence, with 2 being prototypes and 1 currently being used on the Ada Express. By the end of 2025, 15 sets are planned on being produced and by the end of 2030, 56 sets are planned on being produced.
In 2013, TÃÂVASAÃ Â was tasked with the production of domestically-produced diesel and electrical multiple unit trains. TÃÂVASAÃ Â originally planned on first delivering the electrical, and later the diesel multiple units, with a deadline to test the first prototype in December 2018. This date was then postponed to 2020, and later 2022. In 2020, with TÃÂVASAÃ Â merging with other railcar producers to form TÃÂRASAÃ Â, responsibility of the project was transferred to TÃÂRASAÃ Â.
The prototype units were manufactured with a goal of being 65% domestically produced, with the mass produced units having a goal of being 75% domestically made. The traction motor, transformer, transmission, control and management system are all supplied by Aselsan. The train was planned to reach an operational speed of by the end of 2023, but this has since been made its own project.
The testing of the first five E44000 units produced at the Turkish Wagon Production Factory () began in June 2020. After test drives that started in July 2021, 10,000 kilometers were covered as of September 2022. As of April 2023, 3 sets had been completed, with a total of 56 sets being planned to be produced by 2030.
