Data from Ugo Poddine as contributor to Bryan Attewell ([] Steam locomotive simulator (April 2000). Additional data from the US Military Railway Service's Equipment Data Book for Italian Locomotives supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.
Poddine says that builders in Italy, Germany, and Hungary supplied this design from 1889 to 1913. They lasted until the 1960s.
The boiler generated 13,558 lb (6,150 kg) of steam an hour and the design was rated at 500 hp at 18 mph (29 km/h).

This was the precursor to the Gruppo 835, Locobase believes. The grate is smaller, but the boiler is the same size. Thus, boiler production was given by the MRS as 9,240 lb (4,191 kg) per hour and horse power was rated at 370 hp at 18 mph.
According to [] (visited 28 June 2005), this sextet arrived in 1900.

Interesting locomotive in its tube diameter (65 mm on the fire side) and relatively small number of tubes; otherwise it is of a kind with the 829 (Locobase . Steam generation came at 9,900 lb (4,491 kg) per hour and horspe power was rated at 360 hp at 18 mph.

These were built for secondary lines, but were soon adopted for switching duties.
According to the Italian-language website xoomer.virgilio.it/ihydig/museo/sch_835244.htm (June 2004), OMMN delivered 166, Breda produced 150 locomotives, OMRE added 30, and Ansaldo produced 24. Some of these operated until 1980.
Boiler production was given as 9,240 lb (4,191 kg) per hour and horse power was rated at 370 hp at 18 mph.

Built for mountain service on the Rome-Sulmona-Pescara service. When the Mikado tank 940 class was built, these were used for switching duties. It was credited by the MRS with 10,340 lb of steam per hour and rated at 400 hp at 18 mph.

This cross-compound six-coupled tank had large-diameter, internally finned Serve tubes. They were developed from the Gruppo 870 simple-expansion locomotives. They didn't prove suitable for the stop-start commuter traffic for which they were procured. So they were relegated to local freight and passenger work and ended their days switching (shunting) in the Cuneo railway yards.
