In August 2017, Trenes Argentinos suspended the Puente Alsina–Aldo Bonzi service due to a derailment near Puente Alsina station. Since then, the service has not been re-established. Because of that, the National Government ceded the lands occupied by the line to the Municipality of Lanús with the purpose of building a park there. The Buenos Aires station was closed in May 2018, leaving Dr. Sáenz as new terminus of the line. A viaduct was built between Sáenz and Villa Soldati to avoid level crossings. A second stage of the project included to extend the viaduct to Plaza Constitución, connecting both lines, Belgrano Sur and Roca.

Prior to the complete replacement of the existing rolling stock by the Chinese DMUs, the line consisted of a variety of diesel locomotives pulling carriages in a number of different combinations.
