Sur de Espana 0-8-0 Locomotives in Spain


Class Details by Steve Llanso of Sweat House Media

Class 040-2286 (Locobase 3466)

Data from [link] and from [link], which notes that these engines started out with the Sur. They were absorbed by the Andaluces as 241-244, but just one 2286 was taken up by RENFE on its founding in 1941.


Class 234/040-2331 (Locobase 3464)

Data from [link] . See also Justo Arenillas in "Las locomotoras belgas de Andaluces", Lineas Del Tren (as reproduced on (reproduced on [link], viewed 28 April 2003)

These locomotives were purchased directly by the Sur to complement the three they'd acquired when that railway took over the Torralba-Soria (Locobase 3463). Other than an increase in cylinder diameter, they were essentially identical to the earlier engines. Like those engines they too had Belpaire fireboxes and Walschaerts valve gear.

On the Sur, their names were:

104- Sierra de G+dor

105- Sierra Alhamilla

106- Sierra de Baza

107- Sierra de los Filabres

This quartet eventually belonged to the Andaluces (234-237) when that railway was formed and were handed over to the RENFE when the national system formed in 1941.


Class 61/245/040-2551 (Locobase 4910)

Data from [link] . Works numbers were 5055-5056 in 1904 and 5782-5783 in 1907.

The photograph shows a very high-pitched boiler. The dimensions suggest a powerful drag freight locomotive. When the Andaluces took over the Sur, this class was renumbered 245-248 -- RENFE apparently only took up one of the 4, numbering 040-2551.
