In a blog for European Railway Review, Graham Ellis looks at the varying growth of high speed rail services in Spain and Portugal.

The strategy for Portuguese railways 2014-2050

Issue 5 2015 / 1 October 2015 /

Infraestruturas de Portugal, the State-owned company established from the recent merging of REFER, E.P.E.,(railways administrator) and EP-Estradas de Portugal, E.P., (road administrator), both former public infrastructure managers, is putting together an ambitious programme to expand and modernise the rail network in Portugal, supported by EU funds, with a total investment of approximately €2.75 billion. António Ramalho, CEO of Infraestruturas de Portugal, provides more information…

The migration path towards ERTMS in Portugal

Issue 6 2014 / 3 December 2014 /

Interoperability has become a key word in the European transport policy, with the aim of improving transport services. The application/renewal of signalling and telecommunication systems in the Portuguese railway network will follow this legal requirement and migrate to the new European Rail Traffic Management System (ERTMS). Jose P. Neves from REFER Telecom and Fernando Vendas from REFER Engineering, provide more details…

Portuguese rail network developments: Challenges and opportunities

Issue 5 2014 / 18 September 2014 /

Portugal was affected by the international economic and financial crisis, like the majority of European countries, which determined the request for external help in 2011 and materialised with the Economic and Financial Assistance’s Programme. This context involved a change of strategy regarding public investment in transport infrastructures which became effective in October 2011, through the Transports’ Strategic Plan/Sustainable Mobility (PET – Horizon 2011–2015), that laid down the guiding principles for action in this domain. António Viana – Director of Strategy and Network Development at REFER (the Portuguese rail infrastructure manager) explains the direction for the future.

Strong commitment from the Spanish rail industry

Issue 5 2013 / 26 September 2013 /

As the result of a strong commitment to research and development, the Spanish rail industry has made available to the international market a modern fleet of rolling stock vehicles for all kinds of transportation for both passengers and goods, plus the offering of skilled train maintenance services as well as innovative track equipment solutions.

Railway transportation has experienced considerable development over recent years. Its great economic and environmental benefits have made it the best choice for improving connections, re-structuring territories, and contributing to sustainable mobility – for both freight and passengers.

The railway network evolution is closely linked to innovations and advances introduced by the industry in a number of fields such as infrastructure and superstructure, rolling stock and maintenance. All elements are essential in promoting the establishment of new connections and the modernisation of lines already in commercial operation.

Power quality (and monitoring) in railway systems

Issue 5 2013 / 26 September 2013 /

Electrical compatibility between fixed installations and rolling stock, at power supply level, is paramount when dealing with power quality, system availability and reliability. This article addresses power quality and power quality monitoring on alternate current 25 kV electrification systems, focused on overvoltages generated by near resonance frequency harmonics.
Theoretical background

According to Ohm’s Law, when a voltage is applied to an electrical circuit the resulting current flow is inversely proportional to the circuit impedance. By the same law, if an electric current is injected in a circuit the resulting voltage is directly proportional to the circuit impedance.

By definition the electrical impedance is the measure of opposition that an electric circuit presents to the flow of current. In alternating current (AC) the impedance has two components: resistance and reactance. The resistance component is intrinsic to the materials and shape of electrical elements. The reactance relates to the electromagnetic induction phenomena between electrical elements. While resistance is invariable with frequency, reactance is frequency dependent.

Promoting the internationalisation of Spanish railway technology

Issue 5 2012 / 19 September 2012 /

Since my appointment as CEO of Adif, one of my main strategic priorities has been to drive forward the internationalisation of Spanish railway technology and its companies, and to reinforce the ‘Spanish Brand’ on an international basis. By doing so, the international activity of Adif must be, and is, an important pillar of the company’s strategy because it consolidates our presence in the global arena and also paves the way to achieve new markets and, therefore, new economic resources.

In this sense, Adif, as infrastructure manager, works actively with Spanish companies to support them in their internationalisation strategies to help contribute to the projection of the railway sector abroad.

In my opinion, Spain’s experience of railway development would serve as a good example for numerous countries, especially in the technological field of construction and management of high-speed lines. We are proud of the support that we can give for the creation of Spanish consortiums for the design and construction of infrastructure projects abroad.

CP – an attractive transport brand with a clear future focus

Issue 5 2012 / 19 September 2012 /

The Portuguese Government recently decided to lease the suburban railway services of Lisbon and Oporto to the private sector, according its Strategic Plan for Transports, approved by the Council of Ministers Resolution Nº 45/2011 of 13 October 2011. The Government intends to define the model for the new private sector, as well as defining a model for the privatisation/concession of the incumbent – predicted for 2013.

The ongoing liberalisation of the domestic market in Portugal: A series of structural reforms have been adapted in Portugal aimed at enhancing the financial stability of the country’s business sector of the State, which includes CP – Comboios de Portugal, E.P.E.

A number of measures have already been established, including a review of pricing and cuts of operating costs, including the significant reduction of salaries. All of these measures, and others, are aimed at ensuring the long-term financial sustainability of companies.

FBSIC – an innovative tool based on GIS technology

Railway infrastructure managers and operators are huge property owners, managing important railway facility and infrastructure territories. Due to the historical background of the railway industry, valuable real estate assets can be found, and there are certain regulations concerned with urban and suburban environments associated with railway lines, stations, logistic terminals and interfaces, yards and workshops, etc.

The duty of railways to ensure compliance with requirements associated to urban/regional planning of territories, and the need to make adjustments in order to adapt to changing mobility conditions and transport markets (passengers and freight), has historically forced railway companies to introduce functional and topological changes that often disregarded the economic optimisation of property use.

There are many ways to implement real estate/leasing initiatives that can turn into signifi – cant money-making opportunities for the core business of railway entities, while contributing to increasing the transportation market.

Three new connections in the Portuguese network

Issue 6 2010 / 10 December 2010 /

In 2010, REFER EPE – the Portuguese rail infrastructure manager – opens three new connections of great importance for the rail network in Portugal. Three investments in the Main Network, considered as priorities in the Strategic Guidelines for the Railway Sector established by the Portuguese Government in 2006, include the rail link to the Port of Aveiro, the Trofa Bypass and the Alcácer Bypass.
