Class 4700 are a series of medium power electric locomotives built by Siemens for Comboios de Portugal, the state owned railway company of Portugal. 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.[1] The 4700 locomotives are part of the EuroSprinter family of modular locomotives built by Siemens for European railway companies. The machines feature a new cab design, meeting the latest EU safety directives,[1] a design which was continued with the Class 18 locomotives built for the Belgian state railway company.[2]
