Alcantarilla a Lorca 0-6-0 Locomotives in Spain

Class Details by Steve Llanso of Sweat House Media

Class 030-2366 (Locobase 3437)

Data from [], the web site of the Spanish National Railway. See also [], which describes the class. Works numbers were 3209-3214 in 1885.

The AL was one of the smallest Spanish railways, measuring only 57 km (35 miles). Such a small line didn't need many locomotives and, sure enough, these sturdy little Sharps were the only ones the AL would operate. They could be pushed to relatively high speeds when necessary without excessive bobbing and weaving and although fitted with small drivers, were quite suitable for local passenger traffic as well. (Such 0-6-0s were often used in mixed duty outside of North America.)

All of them were taken into RENFE where they served for more than a decade. All but one was scrapped in 1954. 030-2369 is preserved in Museo del Ferrocarril de Vilanova y la Geltr+.
