The "Ankara Metro" has been operating since 29 December 1997, with the opening of its first full metro line, M1, traveling between Kızılay, the city center, and Batıkent. The M2 line, operating from Kızılay, the city center, to Koru, opened 12 February 2014. The M3 line, which serves almost as an extension of the M1 line, operating from Batıkent to Törekent, opened a month later on 13 March 2014. For the first few years of operations on lines M2 and M3, both of them ran separately from the M1 line; since early 2019, the three lines are operated as one continuous service (M1) between Törekent and Koru.
