The transfer center opened on 22 May 2000 together with a new metro station and bus terminals and was the first complex to offer direct connection between heavy rail and rapid transit service in Turkey.

The SCP was bought by the Turkish State Railways in 1934, which continued to operate commuter trains that stopped at Halkapınar.

[6] In anticipation for expanded commuter service to Aliağa, Halkapınar station was electrified with overhead wire.

Between 2006 and 2010, Halkapınar saw a suspension of heavy rail trains, due to the construction of railway tunnels in Şirinyer and Karşıyaka.

[1] Halkapınar has a total of five island platforms serving nine tracks, three for metro, four for heavy rail in the main complex and two in the tram stop.

Prior to 2016, that platform was used by intercity and regional trains to Eskişehir, Balıkesir, Bandırma, Uşak and Konya.

City buses arrive and depart from two separate bus terminals, located on opposite sides of the complex.
