The first Engerth type locomotives procured by the Southern State Railway after the Semmering competition were built in 1853 and 1854 in the Belgian Cockerill works in Seraing. The locomotives each had three coupled axles and behind the ball joint there was a two-axle tender. The firebox was roughly centered over the tender's axles. On four of them the first tender axle was connected to the coupled axles with a gear coupling and the rearmost axle was in turn driven by this via coupling rods, as can be seen in the illustration. Although the entire weight of the locomotive and tender could be used as adhesive weight, the technical implementation did not prove successful.

Only the first 16 locomotives of this series were manufactured by Cockerill. Ten more came from the Esslingen machine factory, the first of which was given the name “Kapellen”. When the railways were privatized in 1858 and the locomotives came to the Südbahn, they became class 19 and later class 33. All were rebuilt between 1861 and 1864, where they received a fourth coupled axle to support the firebox and the supporting tender was replaced by a normal tender. These locomotives were used until 1929.
