Tren Urbano currently operates 15 trains during rush hours, while the remaining cars stand at the yards or serve as backup should a train experience problems. The rolling stock was assembled at the Siemens plant in Sacramento, California . 
With the Government of Salta as operator of the service, the Tren a las Nubes was announced to be running again by March, 2015,   although the service did not begin running again until 4 April 2015. During the 8-month closure of the line, both the National Government and the government of Salta had restored many of the rails as well as the rolling stock.  For that refurbishing, coaches were remodeled by the Province along with freight transport company Belgrano Cargas , while diesel locomotives were repaired at Alta Córdoba workshops.
