was a twin-coupled tender locomotive built for passenger services with the Royal Saxon State Railways.

Based on the design of the Saxon IIIb the Saxon Engineering Works (Sächsische Maschinenfabrik) built a compound engine.

In the years 1889 and 1892 a total of 18 units of the IIIb V were built for passenger train duties.

The locomotives had a boiler made from three shell rings with a semi-circular cover which, in the area of the firebox, was tucked in it between the frame plates.

The locomotiven were coupled to tenders of Saxon Class sä 3 T 9.
