Works number was 1158 in March 1930.
From Roman times, Spain's southern region of Huelva yielded large amounts of iron, copper, sulphur, and other minerals. As the 19th century proceeded, the pace of exploitation picked up and many companies staked claims throughout Huelva.
One was the Scottish company TOS that bought this eight-coupled locomotive to run on the Tharsis-La Zarza-Corrales railroad (sic) that the Google Arts & Culture interactive account says was "the backbone of the ore extraction and transformation system."
