Ferrocarriles Vascongados was a railway company in the Basque Country, Spain; founded in 1906 as the merger of three railway companies. It operated the Bilbao-San Sebastián line, as well as the Elorrio branch and the Deba railway. FEVE took over its operations in 1972, which in 1982 were transferred to the new company Basque Railways. Ferrocarriles Vascongados was dissolved in 1995, after more than two decades without activity.

The Urdaibai line, also known as the Amorebieta–Bermeo railway is a 29.19 km (18.14 mi) mostly single-track branchline in Biscay, Basque Country. Owned by Euskal Trenbide Sarea, it runs from Bermeo to Amorebieta, connecting with the Bilbao-San Sebastián mainline.
