As a Type 78 , the designated Budapest Maschinenfabrik MÁVAG a series of narrow tank locomotive for Bosnian track (760 mm).
history
The type 78 was part of a series of narrow-gauge locomotives that had been designed by MÁVAG especially for field and forest railways . The type 78 machines were built from 1908 to 1914 in a number of 18 machines. In addition to various private industrial railways, the Borzsatalbahn , which serves public transport, and the ku k also belonged. Heeresbahn to buyers of this type.
technical features
The locomotives had a long boiler consisting of two sections with a steam dome . The sandpit was arranged on the second boiler section. The second series, Type 78.1, received a slightly larger steam generator. All wood-fired locomotives were equipped with a Kobel chimney .
A two-cylinder engine with simple steam expansion and Stephenson control served as the steam engine . The third coupling axle was driven.
The driving axles were rigidly mounted in an outer frame.
The water supply of 1.25 m³ was in two lateral water boxes. The fuel supply was behind the driver's cab .

Borzsavölgyi Gazdasági Vasút (Borzsa Valley Railway)
Four new locomotives came to Borzsavölgyi Gazdasági Vasút (BGV) in what was then Upper Hungary in 1909 . They were given the numbers 21 to 24. Two of the locomotives were used by the k.uk. during the First World War. Heeresbahn confiscated, the other two came in 1923 as U 34.001 and U 34.002 in the inventory of the Czechoslovak State Railways (ČSD). When the railway area fell back to Hungary in 1939, they were incorporated into the inventory of the Hungarian State Railways (MÁV) with the numbers 399.103 and 399.104 . There the 399.103 was stationed in Debrecen and was retired in 1961, the 399.104 came to the CFR in 1944 under the same number and was retired there in 1968.
ku k. Army Railway
The k.uk. In 1913, Heeresbahn acquired three MÁVAG type 78.1 locomotives with different parameters. They were given the numbers III 3001 to III 3003. Two of the locomotives came to Nyíregyházavidéki Kisvasutak (NyVKV) after the First World War and in 1939 to MÁV, which classified them as 399.101 and 399.102. The third came to Poland, where it was used by the PKP with the number 1570. During the Second World War, the locomotive belonged to the Deutsche Reichsbahn as 99 2513 .
Further locomotives were from the ku k. Army railway confiscated from various railways. One of these locomotives remained in Czechoslovakia in 1918 and later joined the ČSD fleet as U 35.301.
