The TV was a 2-6-2T tank locomotive intended for branch line service. Between 1907 and 1923, MÁVAG built a total of 596 which had some differences depending on construction year. Most locomotives built between 1908 and 1913 were saturated two-cylinder compounds, while production of a superheated simple started in 1911. The saturated locomotives had an axle load of only 10.3 tonnes, while the superheated ones had an axle load of nearly 11 tonnes.

In addition to the locomotives of the MÁV, more were built for state, private and military railways in Hungary, Czechoslovakia, Romania and Yugoslavia. They had a top speed of 60 km/h and were designated class 375 in the later scheme. Additionally, the MÁV ordered the TVa, later class 376, that had smaller drivers for a top speed of 50 km/h.

After World War I, the ČSD received 58 of these locomotives and designated them class 331.0. They were only used on the Slovak part and many of the saturated compound locomotives received a superheater. Today, some are preserved in different countries. The only operational one is ČSD 331.037 that can be found at Bratislava-Vychod.
