Main reference

Série 9020 was a class of metre-gauge diesel locomotives built by Alsthom for the Portuguese Railways (CP). They entered service in 1975. By the early years of the 21st century the metre-gauge lines on which they operated (such as the Corgo line and the Tua line) have now almost all been closed, resulting in the withdrawal of the locomotives. After their withdrawal, some of the locomotives were sold to Madarail in Madagascar.
