The '''Roca line''' is a {{RailGauge|1676mm}} [[track gauge|gauge]] [[commuter rail]] service in the [[Buenos Aires Province]], [[Argentina]], part of [[General Roca Railway]] network. The service is currently operated by [[Government owned corporation|State-owned company]] [[Operadora Ferroviaria Sociedad del Estado|Trenes Argentinos]], from the city-centre terminus of [[Constitución railway station|Constitución]] south to [[Ezeiza, Buenos Aires|Ezeiza]], [[Alejandro Korn, Buenos Aires|Alejandro Korn]], [[La Plata]], [[Cañuelas]], [[Chascomús]], Gutiérrez and [[Lobos]], and west to [[Sarmiento Line]]'s station [[Haedo, Buenos Aires|Haedo]]. The transfer stations between the branch lines are Avellaneda, [[Temperley, Argentina|Temperley]], Bosques and [[Berazategui]].

The line consists of 198 kilometres of track (55 of which are [[railway electrification system|electrified]]), 70 stations, 146 [[level crossing|grade crossings]], 907 daily services through its different branches, and carries half a million passengers daily, making it the longest and most extensively used line of the Buenos Aires commuter rail network. Large electrification and infrastructure improvement works were undertaken on the line in the early 2010s, with brand [[CSR EMU (Argentina)|new electric multiple units]] entering service on 8 June 2015.<ref>{{cite news|title=Los nuevos trenes del Roca operarán desde el 8 de junio|url=http://www.telam.com.ar/notas/201505/104713-los-nuevos-trenes-del-roca-operaran-desde-el-8-de-junio-anuncio-randazzo-tras-supervisar-las-pruebas.html|archivedate=2019-02-03|archiveurl=http://web.archive.org/web/20190203141020/https://www.telam.com.ar/notas/201505/104713-los-nuevos-trenes-del-roca-operaran-desde-el-8-de-junio-anuncio-randazzo-tras-supervisar-las-pruebas.html|date=12 May 2015|access-date=13 November 2017|language=es|agency=[[Télam]]}}</ref>

[[File:Formación del FCGR entre estaciones Claypole y Rafael Calzada.jpg|thumb|right|A train powered by an [[EMD GT22 Series]] locomotive near Claypole]]
This line had previously been run by the state-owned company [[Ferrocarriles Argentinos]] since [[Railway Nationalisation in Argentina|nationalisation of the Argentine railways]] in 1948. Branches from [[Constitución railway station|Constitución]] to [[Ezeiza, Buenos Aires|Ezeiza]] and [[Glew, Buenos Aires|Glew]] were [[Railway electrification system|electrified]] and the entire fleet of trains renewed, acquiring [[Toshiba EMU (Roca Line)|multiple units]] by [[Japan]]ese companies [[Nippon Sharyo]], [[Kinki Sharyo]], [[Japan Transport Engineering Company|Tokyu Car]], [[Kawasaki Heavy Industries Rolling Stock Company|Kawasaki]] and [[Hitachi]]. The electrified rail system was opened to public in November, 1985.<ref>{{cite web|url=http://portaldetrenes.com.ar/articulos/466/los-electricos-japoneses-del-roca?mkt_hm=3|title=Los eléctricos japoneses del Roca|author=Bilstein, Andrés J.|publisher=Portal de Trenes|date=20 October 2014|access-date=13 November 2017|language=es}}</ref> The design of these Japanese-built cars was based upon the [[Odakyu Electric Railway|Odakyu]] 9000 series, built for the first time between 1972 and 1977.

Ferrocarriles Argentinos operated the trains until 1991 when residual company [[FEMESA]] temporarily took over all the urban services prior to the privatisation of the network. After the Government of [[Carlos Menem]] [[Railway privatisation in Argentina|privatised the urban railways services]], the private company [[Metropolitano]] (TMR) took over Roca Line through concession.

Nevertheless, non-compliance with the terms and conditions (such as lack of investment and poor maintenance of the line, in spite of the large government subsidies received by Metropolitano) led the [[Government of Argentina]] to revoke the contract of concession in 2007.<ref>{{cite news|url=http://www.lanacion.com.ar/910775-kirchner-le-quito-la-concesion-de-trenes-a-metropolitano|title=Kirchner le quitó la concesión de trenes a Metropolitano|trans-title=Kirchner revoked the Metropolitan train concession|work=La Nación|date=22 May 2007|access-date=13 November 2017|language=es|archive-date=13 November 2017|archive-url=https://web.archive.org/web/20171113165220/http://www.lanacion.com.ar/910775-kirchner-le-quito-la-concesion-de-trenes-a-metropolitano|url-status=dead}}</ref> The [[UGOFE]] consortium took over the service until 12 February 2014, when it was announced that the line would be granted to the local [[Emepa Group]].<ref>{{cite news|url=http://www.lanacion.com.ar/1663435-el-gobierno-vuelve-a-privatizar-la-operacion-de-los-trenes-mitre-san-martin-belgrano-sur-y-r|title=Trenes: le dan a Roggio el Mitre y el San Martín y a Emepa, el Roca y el Belgrano Sur|trans-title=Trains: They go to Roggio, the Miter and the San Martin and to Emepa, the Rock and the South Belgrano|work=La Nación|date=12 February 2014|access-date=13 November 2017|language=es}}</ref><ref>{{cite news|url=http://www.clarin.com/politica/privadas-volveran-operar-mayoria-ferroviarias_0_1083491853.html|title=Las privadas volverán a operar la mayoría de las líneas ferroviarias|trans-title=Private companies will re-operate most of the railway lines|work=Clarín|date=12 February 2014|access-date=13 November 2017|language=es}}</ref><ref>{{cite web|url=http://www.telam.com.ar/notas/201402/51395-el-gobierno-establecio-un-nuevo-regimen-de-operaciones-de-las-lineas-ferroviarias.html|archivedate=2022-05-22|archiveurl=http://web.archive.org/web/20220522033454/https://www.telam.com.ar/notas/201402/51395-el-gobierno-establecio-un-nuevo-regimen-de-operaciones-de-las-lineas-ferroviarias.html|title=El Gobierno estableció un nuevo régimen de operaciones de las líneas ferroviarias|trans-title=The Government established a new operating regime for the railway lines|agency=Télam|date=12 February 2014|access-date=13 November 2017|language=es}}</ref>

After the concession was revoked, a temporary consortium named "[[Unidad de Gestión Operativa Ferroviaria de Emergencia|UGOFE]]", took over the Roca line.<ref>{{cite web|author=Sanchéz, Nora|date=20 March 2007|title=En abril arrancaría la etapa final de la electrificación del Roca|trans-title=In April the final stage of the electrification of the Rock would start|work=[[La Nación]]|url=http://www.clarin.com/diario/2007/03/20/laciudad/h-03615.htm|access-date=13 November 2017|language=es}}</ref>

Several projects were announced to modernize the line and improve its service, setting as a priority the electrification of the whole system. Other projects included a new maintenance yard in the town of Tolosa in [[La Plata Partido]], several new bridges and tunnels at road crossings and improved grade crossings, all new concrete sleepers and welded rail joints for the entire line, the remodeling of 50 stations and the purchase of 200 electric coaches of the latest technology.<ref>{{cite web|author=DyN|date=11 March 2008|title=Electrificarán todos los ramales del Ferrocarril Roca|work=perfil.com|url=http://www.perfil.com/contenidos/2008/03/11/noticia_0053.html|access-date=1 March 2016|language=es|archive-url=https://web.archive.org/web/20160303170403/http://www.perfil.com/contenidos/2008/03/11/noticia_0053.html|archive-date=3 March 2016|url-status=dead}}</ref> Presently electrification of Avellaneda-Quilmes and Temperley-Bosques sections are under way.

===Recent developments===
[[File:Roca Line Electrification.jpeg|thumbnail|In recent years, there have been increased efforts to electrify the remaining parts of the line]]
In April 2013 the [[University train of La Plata]] service was opened, using [[railbus]]es built by the Argentine company [[TecnoTren]].<ref>[http://www.infoauto.com.ar/noticias.php?articulo_id=2613 "TecnoTren: La verdad es que nos cuesta muy poca plata fabricarlo" - interview to Jorge Beritich, president of TecnoTren, Infoauto.com]</ref><ref>{{cite news|url=http://www.eldia.com.ar/edis/20130426/Ya-rueda-tren-universitario-20130426080344.htm|title=Ya rueda el tren universitario|trans-title=The university train is already rolling|work=El Día|date=26 April 2013|access-date=13 November 2017|language=es}}</ref> In that same year, Argentine state-owned company [[Operadora Ferroviaria Sociedad del Estado|SOFSE]] announced that brand new [[electric multiple unit]] trains had been acquired for the line's metropolitan services.

The [[Government owned corporation|State-owned company]] [[Operadora Ferroviaria Sociedad del Estado|Operadora Ferroviaria]] took over Roca Line (operated by [[Argentren]]) after the [[Government of Argentina]] rescinded the contracts signed with the company on 2 March 2015.
