Rapport sur le materiel des chemins de fer. p. 50 (cnum.cnam.fr/CGI/fpage.cgi?8XAE277-11.1/54/100/312/0/0 (accessed 1 September 2005) table and page 91. (Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.) Works numbers wer 2151-2154 in 1877 and 2155, 1878 2194-2195 in 1878 and 2330-2333.in 1880.
Beginning in 1877, Fives-Lille delivered a narrow-gauge Mogul tank engine design that featured a Belpaire firebox to the Tramway de Nazare The fifth in the class first appeared in the 1878 Paris Exhbition. The last two finished the class as they joined the others on the the tramway's successor Central Pernambuco.
