Kitson (A8) and Esslingen (A9) supplied this design, which was bigger than the earlier P1s of the same wheel arrangement, had taller drivers, and higher pressure in the boiler. They were about the same size as the 0-4-2s being procured by the London, Brighton & South Coast in England (Locobase 3005) and Spain's Madrid, Zaragoza & Alicante (Locobase 3329), but had taller drivers.
The design was fitted with a Belpaire firebox and a firebox nestled between the second driving axle and the trailing carrying axle. They were first fitted with Ricour vaccuum brakes, which were later replaced by Westinghouse air brakes.
Some of the class ran until the 1920s.

According to the description, these locomotives were originally ordered to operate between Halle and Guben, but were transferred to Elsass-Lothringen (Alsace-Lorraine) after Prussia's victory over France in 1870.
The design was fitted with a Belpaire firebox and a firebox nestled between the second driving axle and the trailing carrying axle. These were classed as passenger engines, but the small drivers suggest low speed.
Some of the class ran until the 1920s.
Data from G F Tyas, "Early Locomotives of the Alsace-Lorraine State Railways", Locomotive Magazine, Volume XXV [25] (15 February 1919), p. 31.
At the same time Kitson delivered 25 2-4-0s to the EL (Locobase 20727), they supplied the railway with 25 smaller mixed-traffic engines. The boiler was smaller, the grate a bit larger, drivers quite a bit smaller. They too had the raised Belpaire firebox, tall dome, and capuchon stack.
Also like the 2-4-0s, these engines first were tested in Britain then partially dismantled and sent by sea from Hull to Antwerp. Two were lost in a storm on the North Sea and Kitson supplied two more locomotives to make up the loss.
