Class Details by Steve Llanso of Sweat House Media

Class 111/321/449/718/3001 (Locobase 20663)

Data from Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T48. (For roster details, see Josef Pospichal's Lokstatistik at [link], last accessed 15 August 2019.) Parent & Schaken works numbers were 132-141 in 1857-1858 (road numbers 111-119, 130), Koechlin's works numbers were 336-342, 391-393 in 1857 (, and Schneider works numbers were 333-352 in 1857.-

Given its size and power, this design couldn't vary too much from all of the other Italian six-coupled freight engines of the time. But it was bigger and had boilers set to a higher pressure; a tall, cylindrical steam dome stood over the middle axle. A small grate and an uneven spacing between drivers were standard.

All 40 locomotives were taken into the Strade Ferrovie dell'Alta Italia (SFAI) in 1865 and 20 years later the entire set served the larger network formed by the Rede Adriatico. But only five remained when Italy formed the Ferro Stato in 1905.

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 100.0 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 161/120/709/773/3001 (Locobase 20649)

Data from Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T46. (For roster details, see Josef Pospichal's Lokstatistik at [link], last accessed 15 August 2019.) Works numbers were 574-583 in 1857.

Resembling most other Italian six-coupled freight locomotives, these French engines had no steam dome. Just behind the stack a small regulator distributed steam from the dry pipe through outside pipes to the inside valves.

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 85.0 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 183/322/450/714/778/3948/3971 (Locobase 20650)

Data from Ferrovie Dell' Alta Italia, Album Delle Locomotive (Torino, 1o Luglio 1876), T47. (For roster details, see Josef Pospichal's Lokstatistik at [link], last accessed 15 August 2019.) Works numbers were 218-221 in 1857-1858.

A relatively large design with tall drivers, these four engines were built by the company that would be renamed Fives-Lille in 1865. The grate was quite small for the size of the firebox and the boiler's heating surface area.

But all four engines survived to be taken into the Rede Meterraneo from the SF Alta Italia (SFAI). And three were taken into the Ferro Stato in 1905.

Locobase found an inconsistencies between the given values for the tube diameters, tube lengths, and for the evaporative heating surface area given as 95.0 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.
