service between Santiago and Nos was completed. The project added two, brand new lines for exclusive use of the service, renovations in electrification, infrastructure, and rolling stock, with the tunneling of every level crossing and station mezzanines, and the purchase of new X'Trapolis Modular trains, based in the Civia train, to Alstom. The services reduced the time of travel to Nos to less than 40 minutes. In 2017, the service formally started and it was definitely integrated to the Santiago public transport system. During this time, it was decided to scrap the plans for an express service to Rancagua because of the costs of the new rolling stock, and the service restarted in 2017 as it was before the renovations. Also, given the low profitability of services to San Fernando and the renovation work, the Metrotren stopped all frequencies to the town in 2013, letting the station only served by the Santiago-Chillan service with 2 frequencies every day. The local authorities of the towns between Rancagua and San Fernando, and the authorities of San Fernando itself had continuously demanded to the central government to restart services, specially after the effects of the COVID-19 pandemic, which represented a hard hit to the tourism sector of the zone. The government promised the restoration of rail services in the second half of 2021. In 2021, all EFE services, with the sole exception of the Biotren, were rebranded to give generic and separated denomination to the services. This led to the end of the Metrotren brand after almost 31 years. The services are branded now as the Santiago-Rancagua line, and the Santiago-Nos line.
