REFER, Rede Ferroviária Nacional, EP (i.e. National Railway Network) was the Portuguese rail infrastructure manager. It was a state-owned company and was created to manage the Portuguese rail infrastructure, previously under control of CP, which became exclusively a train service operator.
It was incorporated on 29 April 1997 by government decree no. 104/97 and was 100% owned by the Portuguese state.
As per a decree-law dated 29 May 2015 and taking effect as of 1 June 2015, Portugal’s rail infrastructure manager REFER, EP has merged with Estradas de Portugal S.S., the Portuguese road manager, creating a new company called ‘Infraestruturas de Portugal, S.A.’
All duties and competences of Estradas de Portugal and REFER, EP, have therefore been transferred to Infraestruturas de Portugal.
The Portuguese railway network consists (2010) of 2,843 km of track:
The first railway in Portugal was between Lisbon and Carregado, now referred to as the Linha do Norte; it opened on 28 October 1856. It was extended to Porto, joining Portugal's two largest cities, in 1877.
Meanwhile, on 1 February 1861 the lines between Barreiro Pinhal Novo and Vendas Novas (the Linha do Alentejo) and between Pinhal Novo and Setúbal (the Linha do Sul) followed.
The Linha do Sul, at 274 km was the principal main line in the south of the country, but it terminated short of Lisbon on the south side of the river Tagus (Tejo in Portuguese) but it received a considerable improvement when it was extended from Pinhal Novo to Lisbon over the Ponte 25 de Abril, which was provided with an additional railway deck.
The earliest railways in Portugal were built to standard gauge (1,435 mm) but were regauged in the nineteenth century for compatibility with the trains of the railways of Spain, which at that time used a track gauge of 1,668 mm.
First electrification in Portugal was the suburban line from Lisbon to Cascais, at 1,500 V d.c., but it was another 30 years before the next electrification, the Norte line between Lisbon and Carregado, on 28 October 1956, exactly 100 years from the line's opening. This electrification was at 25 kV 50 Hz.
Through routes to Spain are single-track and are not completely electrified.
A number of new high speed lines are planned. These were to be built in standard gauge to allow easy connection with the Spanish high speed network but most have since been downgraded.
In addition some minor schemes are now to be completed :
