The StEG category Vd designated 13 0-8-0T tank locomotives built between 1879 and 1891 by their own factory in Vienna. Their original numbers were 1301 to 1313. Like other StEG locomotives, the French influence could clearly be seen. They had inside frames, outside cylinders and outside Stephenson valve gear. The long boiler and the short wheelbase of only 3,555 mm resulted in long overhangs. The first and fourth driving axles had 8 mm of lateral play, what led to a rigid wheelbase of only 1,185 mm. Later, the boilers were equipped with two interconnected domes. 

The first four were built for the steep Oravica-Anina in today's Romania with inclines of up to 2.1 percent. The other nine were used as shunters in several places. In 1891, the nine locomotives on the Hungarian part of the network became MÁV TIV, later class 450. When the Austrian part of the StEG was nationalized in 1909, the four other locomotives became kkStB class 378. After World War I these became ČSD class 403.3. There they were used until 1939 and after that 403.303 came to a sugar works in Bohemia. Today it is on display in the museum in Jaroměř as the only survivor of the class.
