The portion of the rail line from Ankara Station to Sincan was completed in 1892, and a few trains ran daily on it.
It was not until TCDD took over the line that a few suburban trains were put into service. Original service was by a steam engine locomotive, pulling up to 3 cars. In 1972, the line was electrified, and the E14000 units were put into service. In 2010, the new E23000 sets replaced the old ones.
On 11 July 2016, the line was closed for 18 months for complete rebuilding (stations and rail lines). It reopened on 12 April 2018 as part of the metropolitan network, with payment by AnkaraKart; four of the 28 stations, Subayevleri, Motor Fabrikası, Gülveren and Topkaya, did not reopen.
