Série 2550 were the second batch of 25 kV electric locomotives built for Portuguese Railways (CP). They entered service in 1964 and were used on the main line between Lisbon and Oporto. 20 locomotives were built; as of 2012 none remain in service. [1] Unlike the earlier Série 2500, the Série 2550 were built with unpainted stainless steel bodywork. They were constructed by Sorefame, with components from the French company Alsthom.

Comboios de Portugal Portuguese railway company

CP — Comboios de Portugal, EPE is a state-owned company which operates passenger trains in Portugal. Before June 2009, CP stood for Caminhos de Ferro Portugueses although the company has been using its current designation as a brand name since 2004.

Lisbon Capital city in Lisbon Metropolitan Area, Portugal

Lisbon is the capital and the largest city of Portugal, with an estimated population of 505,526 within its administrative limits in an area of 100.05 km2. Its urban area extends beyond the city's administrative limits with a population of around 2.8 million people, being the 11th-most populous urban area in the European Union. About 3 million people live in the Lisbon Metropolitan Area, including the Portuguese Riviera,. It is mainland Europe's westernmost capital city and the only one along the Atlantic coast. Lisbon lies in the western Iberian Peninsula on the Atlantic Ocean and the River Tagus. The westernmost areas of its metro area form the westernmost point of Continental Europe, which is known as Cabo da Roca, located in the Sintra Mountains.

Stainless steel steel alloy resistant to corrosion

In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable (inoxidizable), is a steel alloy, with highest percentage contents of iron, chromium, and nickel, with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass.

The Série 4700 were built in 2007-2009 as a replacement for the Série 2550.

CP Class 4700 locomotive class

Class 4700 are a series of medium power electric locomotives built by Siemens for Comboios de Portugal, the state owned railway company of Portugal. They were built to replace the CP Class 2550 locomotives dating from the early 1960s. Siemens were the natural choice for the original order for 15 machines, placed in 2006, as they built the older Class 5600 locomotives in the 1990s. An option for 10 further locomotives was provided for, and this was taken up in 2007, with delivery following on from the original batch.
