CP Class 2550

The 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 Porto. Twenty locomotives were built with all withdrawn by 2012. Unlike the earlier Série 2500, the Série 2550 were built with unpainted stainless steel bodywork. They were built by Sorefame, with components from Alstom. The Série 4700 were built in 2007-2009 as a replacement for the Série 2550.
