Data from [], the web site of the Spanish National Railway. See also the Madrid Railroad Museum's (Museo de Ferrocarril de Madrid) website at [], last accessed 9 April 2015. Three (works numbers 17647-17649) arrived in 1907, three more in 1909.
Combining a high-pitched boiler with Belpaire firebox and outside valve gear, this were a sextet of low-drivered freighters built originally for this Portuguese railway. According to the MdFdM website, their design harked back to a set of older Ten-wheelers of Scotland's Highland Railway known as the Castles (Locobase 3021). They were later sold to the Medina del Campo a Zamora, Orense y Vigo (M.Z.O.V) in Spain and taken into RENFE in 1941.
