The TVV 73-77 were passenger train - tender - steam locomotives of the Tisza Railway (Tiszavidéki Vasút, TVV).
The TVV ordered five passenger locomotives from Günther in Wiener Neustadt in 1860 . In addition to the road numbers 73-77, the vehicles were given the names BARON BRUCK , VÁSONKEÖ , KOROMLA , NAMÉNY and M. SZIGET .
In 1867 the five machines were sold to the First Transylvanian Railway (Első Erdélyi Vasút, EEV). There the locomotives were given the numbers 11–15 and the names GYÖRÖK , SOBORSIN , DÉVA , PÍSKI and ALVINCZ .
In the course of the nationalization that took place in 1884, the Hungarian State Railways (MÁV) initially gave them the numbers 290–294, and from 1891 in the second designation scheme the category IIk with the numbers 1211–1215. From 1911 they were listed as 256.001–005.
