The MÁV I was the first outspoken fast - Tender Locomotive series of Hungarian State Railways MÁV for the express train service on main routes:
The six machines were supplied by the StEG locomotive factory in 1874. They belonged to the Rittinger type typical of Austria-Hungary at that time. The rear coupling axle was relocated behind the standing boiler. The two running axles were designed as a bogie.
The MÁV gave the machines the numbers 159–164 in their first designation scheme. In the second scheme from 1891 they were classified as Category I with the numbers 1-6. In the third scheme valid from 1911 they were given the designation 259,001–006.
In operation, the vehicles proved to be too weak due to insufficient steam generation.
