Alquife Mines & Railways 2-8-0 Locomotives in Spain
Class Details by Steve Llanso of Sweat House Media
Class 140-2025 (Locobase 3369)
Data from [
], the web site of the Spanish National Railway and [].
This site notes that the Andaluces later took this Belpaire-firebox class up as the first four engines in a larger group that included identical engines operated by the Sur de Espana. RENFE (1941) took all four Consolidations.
