Lombardo-Veneto 2-2-2 Locomotives in Italy


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 10733)

Data from "Der Lokomotivestand der Sudtiroler-Ventiantishen Eisenbahn i. J. 1963", Die Lokomotive (1917), pp.65-69. E L Ahrons, M I Mech. E, "Early English Express Engines in Italy", The Locomotive Magazine, Vol XV (15 September 1909), p. 175; and Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T6. Works numbers were 1101-1150.

These singles entered service on the LV at the same time as the Beyer, Peacock locomotives described in Locobase 10731. They had slightly bigger fireboxes, but were otherwise similar. Die Lokomotive's extensive report included a list of manufacturers that indicates the data shown in this entry's specs refer to the first 15 from Robert Stephenson & Company and 16-25 delivered by Beyer-Peacock in the same year.

In 1865, the LV was taken into the SFAI and renumbered 31-80. SFAI rebuilt 11 of the class into 2-4-0s with the same driving wheel diameters, but larger 16 1/2" cylinders (Locobase 20585).

During the next reorganization in 1885, 8 (511-518) went to the Rete Mediterraneo, while the Adriatic took 22 of the singles and all of the 2-4-0s (numbered 1101-1111). All of the ex-Adriatic locomotives were scrapped between 1898 and 1904 and 3 of the RM engines were nationalized by the FS in 1905.


Class 81 (Locobase 10731)

Data from E L Ahrons, M I Mech. E, "Early English Express Engines in Italy", The Locomotive Magazine, Vol XV (15 September 1909), p. 174; and Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), . T7. Works numbers were 56-65.

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 82.5 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.

Ahrons notes that these locomotives were incorporated into the Strade Ferrate Alta Italia (SFAI) in 1865. In 1885, the Rete Mediterraneo took them over as 501-510. Four remained to be incorporated into the FS in 1905. By that time they had new boilers with 940 sq ft (87.33 sq m) of total heating surface, of which 80 sq ft (7.43 sq m) was supplied by the firebox.
