This British-built set of 0-4-2s came from the country that introduced the wheel arrangement and may have inspired Giovanni Ansaldo's large homebuilt class described in Locobase 20598.

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 73.8 sq m. The EHS value shown in Locobase's specs is composed of the firebox heating surface area given in the diagram and the tube heating surface area calculated from the stated tube length, external tube diameter, and count.

Class 250/FS 111 (Locobase 20602)

Data from Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T22. The first six went to the Strade Ferrate dello Stato Piemontese in 1855 as the SFSP's 99-104. Three more were delivered to the Victor Emmanuel Railway (VE) in 1860. (Roster information from [], last accessed 15 August 2019).

Locobase 20601 describes the first six 0-4-2s from Robert Stephenson & Co. This nonet followed almost immediately and duplicated the design except for rolling on smaller drivers. Slight variations in weights and dimensions are much less visible in the SFAI diagrams than the built-up firebox on a boiler that had the sandbox, steam dome, and stacked bunched at the very front.

Taken into the Rete Mediterranea (RM) network in 1885, all but one of the class were placed in the new Ferrato de Stato Italiane (FS) in 1905 as the 111 class.

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 73.7 sq m. The EHS value shown in Locobase's specs is composed of the firebox heating surface area given in the diagram and the tube heating surface area calculated from the stated tube length, external tube diameter, and count.

Class 277 (Locobase 20612)

Data from Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T26. These were the first two locomotives turned out by the Ansaldo works.

At around the same time that Ansaldo delivered the 210 class to several railways (Locobase 20598), it produced these two for still another railway. With very minor differences, the pair duplicated the 210s. They were taken into the SFAI on its amalgamation of other railways in Upper Italy in 1865. Twenty years later, the SFAI itself was combined with two other networks to form the Rete Mediterranea (RM).

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 81.7 sq m. The EHS value shown in Locobase's specs is composed of the firebox heating surface area given in the diagram and the tube heating surface area calculated from the stated tube length, external tube diameter, and count.

Class 282 (Locobase 20614)

Data from Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T26. (For roster details, see Josef Pospichal's Lokstatistik at [], last accessed 15 August 2019.)

Gouin's 1862 passenger locomotives joined other French-built locomotives in rolling on relatively tall drivers. This batch, likely supplied to a different railway than the 279 trio shown in Locobase 20613, had three axles as well, but led with the two driven sets. Although their boilers included a relatively high amount of heating surface (among the largest anywhere at the time), their grates remained small.

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 101.5 sq m. The EHS value shown in Locobase's specs is composed of the firebox heating surface area given in the diagram and the tube heating surface area calculated from the stated tube length, external tube diameter, and count.
