The Compañía de los Ferrocarriles de Lorca a Baza y Águilas, also called Great Southern Railway of Spain, was mainly built to haul iron ore from the Sierras to the port of Águilas. They received the first six Moguls in 1889 from Neilson in Scotland. These locomotives had a large grate and a high boiler pressure for this time. They were built for mixed traffic with a driver diameter of 57 inches (1,448 mm) and had an output of around 700 hp.
Neilson delivered six more in 1890, followed by two from Kitson in 1894, five from Sharp, Stewart in 1901 and six from North British in 1905. When RENFE was founded in 1941, all were still in service and got the numbers 130.2121 to 130.2145. They started to be withdrawn in 1966. Only 130.2124 was preserved, today it is on static display at Águilas.
