The MÁV Ih was an express train - steam locomotive series of the Hungarian State Railways MÁV.
The MÁV needed triple-coupled express locomotives for their mountain routes. So they had nine wet steam twin locomotives built with the 2C wheel arrangement in Budapest . These were the first European vehicles with this wheel arrangement. The boiler was very similar to the MÁV Ie range . They also had an outer frame and an outer Heusinger control.
In the second MÁV scheme, the nine twin locomotives were listed as Category Ih with the numbers 641–649. In the third scheme valid from 1911, they were given the designation 320,001–009.
The MÁV Ik series was procured in order to be able to compare the Ih series with its twin engine with a compound engine . The comparison was in favor of the Ik series.
In September 1919 eight of the nine locomotives came to the Romanian State Railways CFR, which they decommissioned in 1924 and 1925. The 320,007 remaining to MÁV was removed from the inventory in 1933.
