Administrador de Infraestructuras Ferroviarias

ADIF (Spanish pronunciation: [aˈðif], an acronym of Administrador de Infraestructuras Ferroviarias) is a Spanish state-owned railway infrastructure manager under the responsibility of the Ministry of Development, charged with the management of most of Spain's railway infrastructure, that is the track, signaling and stations.[4] It was formed in 2005 in response to European Union requirements to separate the natural monopoly of infrastructure management from the competitive operations of running train services. It is the legal successor of RENFE, FEVE (Ferrocarriles de Vía Estrecha), and GIF (Gestor de Infraestructuras Ferroviarias).

ADIF is the result of Railway Sector Act, which arises from the transposition of European Directives. It requires that large European national railway independently manage the infrastructure and trains on it. The ultimate goal was to allow any other rail operator operating on the network to do so on equal terms with the operator, in this case, Renfe, promoting free competition. The RENFE division became effective on 1 January 2005 between the two companies:

  1. Renfe Operadora (newly created entity): Owner of trains and responsible for its circulation, which works in competition with other railway companies
  2. ADIF (Legal successor of RENFE): Owner of infrastructure and responsible for its management, which provides its services to any rail operator who requests

A similar operation was conducted on 31 December 2012 with FEVE, a company that managed the narrow gauge railways. ADIF took charge of all narrow gauge infrastructures not transferred to the autonomous governments.


ADIF is responsible for administrating rail infrastructures (tracks, stations, freight terminals, etc.), managing rail traffic distributing capacity to rail operators, and the collection of fees for infrastructure, station and freight terminal use [5]

Alta Velocidad Española (AVE) is a service of high-speed rail in Spain operated by Renfe, the Spanish national railway company, at speeds of up to 310 km/h (193 mph). Alta Velocidad Española translates to "Spanish High Speed", but the initials are also a play on the word ave, meaning "bird". As of August 2017, the Spanish AVE system is the longest HSR network in Europe with 3,240 km (2,010 mi) and the second longest in the world, after China's.AVE trains run on a network of high-speed rail track owned and managed by ADIF (Administrador de Infraestructuras Ferroviarias), where other high-speed (Avant, Alvia) and mid-speed (Altaria) services also operate. The first line was opened in 1992, connecting the cities of Madrid, Córdoba and Seville. Unlike the rest of the Iberian broad gauge network, the AVE uses standard gauge. This permits direct connections to outside Spain through the link to the French network at the Perthus tunnel. AVE trains are operated by RENFE, but private companies may be allowed to operate trains in the future using other brands, in accordance with European Union legislation. Some TGV-derived trains used to run on the broad-gauge network at slower speeds, but these were branded separately as Euromed until new rolling stock was commissioned for these services.

Arc Infrastructure

Arc Infrastructure (previously known as Brookfield Rail and WestNet Rail) is a transport infrastructure owner and access provider in Western Australia with a long-term lease on the network from the Government of Western Australia. It operates approximately 5,500 km of standard, narrow and dual gauge rail infrastructure in the southern half of the state.

California High-Speed Rail

California High-Speed Rail (abbreviated CAHSR or CHSR) is a publicly funded high-speed rail system under construction in the U.S. state of California. It is projected to connect the Anaheim Regional Transportation Intermodal Center in Anaheim and Union Station in Downtown Los Angeles with the Salesforce Transit Center in San Francisco via the Central Valley, providing a one-seat ride between Union Station and San Francisco in 2 hours and 40 minutes, a distance of 380 miles. Future extensions are planned to connect to stations in San Diego County via the Inland Empire, as well as to Sacramento.

CAHSR plans to operate on dedicated, grade-separated tracks for the entirety of its route between San Jose and Burbank with speeds of up to 220 miles per hour (354 km/h), with early ridership projections for the San Francisco to Los Angeles leg at 28.4 million per year. The San Francisco–San Jose and Los Angeles–Anaheim sections will be shared with local trains in a "blended system". The project is owned and managed by the state of California through the California High-Speed Rail Authority (CHSRA). The Bakersfield to Los Angeles segment would be the first instance of a direct passenger train route between the cities since the termination of the Southern Pacific Railroad's San Joaquin Daylight in 1971.

The CAHSRA was established by an act of the California State Legislature and tasked with presenting a high-speed rail plan to the voters. This plan, Proposition 1A, was presented to and approved by voters in 2008 and included a $9-billion bond to begin construction on the initial leg of the network. Construction began in 2015 after a groundbreaking ceremony in Fresno. The ARRA funding agreement, which CAHSR intends to utilize to build the Central Valley segment, specifies a completion date of December 31, 2022, and the 2018 draft Business Plan calls for opening the initial operating segment between San Jose Diridon station and Bakersfield in 2027. The complete first phase between San Francisco and Anaheim is expected in 2033. Phase 2 extensions to Sacramento and San Diego are still in the planning stages.

On February 12, 2019, Governor Gavin Newsom in his first State of the State address announced that, while work would continue on the 171-mile (275 km) Central Valley segment from Bakersfield to Merced, the rest of the system would be indefinitely postponed, citing cost overruns and delays. Project costs have escalated significantly from an initial estimate of $33.6 billion in 2008 for the Anaheim to San Francisco section according to the 2008 business plan, and a $40 billion total figure given to voters whose approval was sought in 2008. The 2008 business plan proposed a 2028 completion date for Phase 1 and a one-way fare of $55 from Los Angeles to San Francisco. In 2012 the Authority re-estimated the project's cost at $53.4 billion (2011$) or $68.4 billion (YOE). In 2018 the Authority pushed estimated costs to between $63.2 billion and $98.1 billion (YOE) and delayed initial service to 2029, with Los Angeles to San Francisco service in 2033. However, environment reviews for the entire San Francisco to Anaheim route would continue. The cost for Bakersfield to Merced is $12.4 billion.

Castile and León

Castile and León (UK: , US: ; Spanish: Castilla y León [kasˈtiʎa i leˈon] (listen)) is an autonomous community in north-western Spain.

It was created in 1983. Formed by the provinces of Ávila, Burgos, León, Palencia, Salamanca, Segovia, Soria, Valladolid and Zamora, it is the largest autonomous community in Spain in terms of area, covering 94,222 km2. It is however sparsely populated, with a population density below 30/km2. While a capital has not been explicitly declared, the seats of the executive and legislative powers are set in Valladolid by law and for all purposes that city (also the most populated municipality) serves as de facto regional capital.

Castile and León is a landlocked region, bordered by Portugal as well as by the Spanish autonomous communities of Galicia, Asturias, Cantabria, the Basque Country, La Rioja, Aragon, Castilla–La Mancha, the Community of Madrid and Extremadura. Chiefly comprising the northern half of the Inner Plateau, it is surrounded by mountain barriers (the Picos de Europa to the North, the Sistema Central to the South and the Sistema Ibérico to the East) and it is drained by the Douro River, flowing west toward the Atlantic Ocean.

The region contains eight World Heritage Sites. UNESCO recognizes the Cortes of León of 1188 as the cradle of worldwide parliamentarism.

Community of European Railway and Infrastructure Companies

The Community of European Railway and Infrastructure Companies (CER) brings together 75 railway undertakings and infrastructure companies from the European Union, the candidate countries (North Macedonia and Turkey) as well as from the Western Balkan countries, Norway, and Switzerland.The CER is also a member of Group of Representative Bodies.

O Porriño derailment

On 9 September 2016, a passenger train travelling from Vigo, Spain to Oporto, Portugal derailed at O Porriño, Galicia, Spain. Four people were killed and 49 were injured, seven seriously.

Orbital Railway Line

The Barcelona orbital line (Catalan: línia orbital) is a railway project forming part of both the Pla d'infraestructures de Catalunya (PITC), a long-term development plan due for completion in 2026, and the Pla de transport de viatgers de Catalunya (PTVC), a short-term plan due for completion in 2012. In following perimeter routes the orbital line and another railway project, the Eix Transversal Ferroviari de Catalunya, are the first railway schemes to depart from the radial system developed so far in the Barcelona area.Also known as the Quart cinturó ferroviari, the orbital line will connect Rodalies Barcelona services between Vilanova i la Geltrú and Mataró via a 119 kilometres (74 mi) line passing through Granollers, Sabadell, Terrassa, Martorell and Vilafranca del Penedès, but avoiding the actual city of Barcelona. Some sections will make use of existing track belonging to Administrador de Infraestructuras Ferroviarias (Adif) and operated by Renfe Operadora, whilst 68 km of track - of which 46 kilometres (29 mi) in tunnels - and 23 new stations will be constructed.

Rail transport in Spain

Rail transport in Spain operates on four rail gauges and services are operated by a variety of private and public operators. The total route length in 2012 was 16,026 km (10,182 km electrified).Most railways are operated by Renfe Operadora; metre and narrow-gauge lines are operated by FEVE and other carriers in individual autonomous communities. It is proposed and planned to build or convert more lines to standard gauge, including some dual gauging of broad-gauge lines, especially where these lines link to France, including platforms to be heightened.

Spain is a member of the International Union of Railways (UIC). The UIC Country Code for Spain is 71.

Renfe Operadora

Renfe Operadora (Spanish pronunciation: [ˈreɱfe opeɾaˈðoɾa]) is the state-owned company which operates freight and passenger trains on the 1,668 mm (5 ft 5 21⁄32 in) Iberian gauge, the 1,435 mm (4 ft 8 1⁄2 in) standard gauge and the 1,000 mm (3 ft 3 3⁄8 in) metre gauge networks of the Spanish national railway infrastructure company Adif (Administrador de Infraestructuras Ferroviarias—Railway Infrastructure Administration).

Track gauge

In rail transport, track gauge or track gage is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails.

All vehicles on a rail network must have running gear that is compatible with the track gauge, and in the earliest days of railways the selection of a proposed railway's gauge was a key issue. As the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network.

In some places there is a distinction between the nominal gauge and the actual gauge, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, and this device is also referred to as a track gauge.

The terms structure gauge and loading gauge, both widely used, have little connection with track gauge. Both refer to two-dimensional cross-section profiles, surrounding the track and vehicles running on it. The structure gauge specifies the outline into which new or altered structures (bridges, lineside equipment etc.) must not encroach. The loading gauge is the corresponding envelope within which rail vehicles and their loads must be contained. If an exceptional load or a new type of vehicle is being assessed to run, it is required to conform to the route's loading gauge. Conformance ensures that traffic will not collide with lineside structures.


VicTrack, the trading name of Victorian Rail Track Corporation, is a Victorian Government state-owned enterprise which owns all railway and tram lines, associated rail lands and other related rail-related infrastructure in the state of Victoria, Australia, with the exception of the heritage Puffing Billy Railway that is owned by the Emerald Tourist Railway Board.

VicTrack leases railway and tram land used for public transport to Public Transport Victoria which then sub-leases the assets and infrastructure to rail and tram operators, currently Australian Rail Track Corporation (ARTC), Metro Trains Melbourne, V/Line and Yarra Trams. VicTrack retains responsibility for the freight lines around the Dynon Intermodal Freight Terminal, South Dynon Locomotive Depot and in North Melbourne.VicTrack also carries out a range of commercial activities on railway land, including:

property leasing and licensing of surplus railway land

providing telecommunications services using surplus railway network capacity
