This class was the first express train locomotive with the Bavarian state railways. It was developed from the Class A IV. Unlike the A IV, the Class A V had a lower-pitched boiler and a wider firebox. In addition access to the valve gear was improved. Later still the vehicles were fitted with a steam dome. Because engines on the southern side of the Danube were fired with peat, they had a pear-shaped chimney. In addition these locomotives had different dimensions.

They were equipped with a 3 T 4.8 tender.
