2-2-2 Steam Locomotives in Italy

Class 1 (Locobase 6231)

Data from users.libero.it/allesandro.tuzza/fonti/sfr/1879sfrindice.htm (8 July 2004), an 1878 album of locomotives for the SFR reproduced by Allesandro Tuzza. (Reference: 18785751 STRADE FERRATE ROMANE Album delle locomotive Firenze : Benelli, 1878, found in bibliography at [], Tavola 1, last accessed 28 July 2007)

An upright single-wheeler with inclined cylinders within the plate frame. For Canada Works they were locomotives 143-149, and 154-160. Compared to the British 2-2-2s, these were quite a bit smaller.

Class 25 (Locobase 6232)

Data from users.libero.it/allesandro.tuzza/fonti/sfr/1879sfrindice.htm (8 July 2004), an 1878 album of locomotives for the SFR reproduced by Allesandro Tuzza. (later cite: [], Tavola 2)

This 2-2-2 was small in almost every respect, even when first delivered by Sharp, Stewart (works #1040).

The Album data contain an inconsistency that Locobase can't resolve with available information. The stated evaporative heating surface area--55.30 sq m--is approximately 20% too low when compared to the sum of firebox heating surface area and the calculated tube heating surface area. Locobase's specifications adjust the EHS to reflect the higher value.

Class 41 (Locobase 6233)

Data from users.libero.it/allesandro.tuzza/fonti/sfr/1879sfrindice.htm (8 July 2004), an 1878 album of locomotives for the SFR reproduced by Allesandro Tuzza (later cite: [], Tavola 3). See also Alexandre Louis Deghilage, Origine de la Locomotive (Paris: Imprierie A Broise et Courtier, 1886), p. 38. (Thanks to Teemu Koivumaki for his 4 January 2021 email supplying the link to Luigi M Impallomeni, "Locomotive impiegate nelle strade ferrate granducali 1844-1860", archived at []. last accessed 1/12/2021). Its summary of Grand Ducal locomotives has been very helpful. Works number was 400 in 1844.

See Locobase 3238 for a brief history of the Leopolda.

This was a Stephenson longboiler by all appearances with the three axles grouped in the middle, the inside cylinders and stack ahead, and the haystack boiler behind. Deghilage describes the design (with these same dimensions) as operating on "divers chemins de fer".

The engine survived to be taken into the Strade Ferrate Romane in 1865 as their #41.
