These were repeats of the P & S 2-4-0s of 1855 shown in Locobase 13418. They had 4 more tubes that were a little more than 5" longer. The 1860 batch built by successor Cail were a little lighter, but otherwise identical.
An 1873 modification resulted in a domed boiler. See Locobase 13420 for an example of an updated engine's resulting weights and areas.
Renumberings came in 1880 (824-833, 892-905) with a couple being renumbered 3 366-3 376, -3 390 in 1921.
Like the 824s, this class operated mixed-traffic service for over 50 years. Retirements occurred over the 1908-1924 period.

The builder would be reorganized as Fives-Lille in 1861 and continue building locomotives until the end of steam. This set followed a set of single-drivered locomotives described in Locobase 13362.
The locomotives were updated several times chiefly to increase boiler pressure; the big alteration in 1873 resulted in a domed boiler.
Remarkably, all of the class remained in service for over 50 years. 828 was withdrawn first in 1909, 824-825 followed in 1910, 830 in 1911, 826, 829, and 833 in 1912. It wasn't until 1919-1922 that 827-828 and 831-832 were retired.
