Data from a table in Walter Hefti's Dampf Strassebahn Locomotives in Welt (colaboracion de Don Enrique Andres Gramaje), presented by Gustavo Vieites Brignolo, website editor of es.geocities.com/gustavovieites1/materialrodantef.html (accessed 8 December 2005). This website covers Companias de Tranvias de Madrid.
If Locobase correctly interprets the notes in Hefti's columns, this class originally served the Madrid-Arganda line; two of the class were later incorporated into the (CMU) as 10-11.
