Line 2 runs east–west from Déli pályaudvar in Buda's Krisztinaváros, through the city center, to Örs vezér tere in eastern Pest. It offers connections to Hungarian State Railways at Déli and Keleti pályaudvars, to metro Lines 1 and 3 at Deák Ferenc tér, to line 4 at Keleti pályaudvar, to suburban railway lines 8 and 9 at Örs vezér tere, and to suburban railway line 5 at Batthyány tér. Prior to line 4's opening, it was (for more than 45 years) the only metro line that served the Buda side of the river. Line 2 underwent major reconstruction in the late oughts, with all of the track and stations completed in 2008
