Due to an increase in traffic, Ferrocarriles Vascongados decided in the 1920s to electrify most of its network.

A series of six railcars was ordered to Ganz in 1928 for use in the Bilbao-San Sebastián line.

However, these trains were too long to negotiate the tight curves in the Deba railway [es], so Ferrocarriles Vascongados bought another five railcars from Ganz.

These railcars were mechanically identical to the other series, but were noticeably shorter.

In 1989 it was selected for preservation at the Basque Railway Museum, and in 1995 it was restored by CAF in its Irun facilities.
