Today we are back in Buenos Aires, Argentina. We are riding the Roca Line, a super busy suburban railway line, from Plaza Constitución station in Buenos Aires to La Plata. At La Plata, we transfer to the Tren Universitario (University Train). This short line uses Swedish-built, formerly Portuguese NOHAB 0100 series. They were built in 1948 and shipped to Argentina in 2015 to replace the failed TechnoTrain.
