The locomotives No. 1-6 of Steyrtalbahn were a narrow-gauge - Steam Locomotive series for 760 mm track width which has been specifically developed for this route. It is the predecessor of the U series  , which is one of the most built narrow-gauge locomotives in Europe. After 1953 they were given the series designation 298.1 at what was now ÖBB . This type of locomotive was also procured from other private local railways in what was then Austria .

history

For the opening of the first section of the Steyrtalbahn in Upper Austria , three tank locomotives with a track width of 760 mm were procured from Krauss in Linz in 1888 (locomotives 1–3). These locomotives were designed as two-cylinder wet steam engines with external controls of the Heusinger type with flat slide valves.

A construction with three coupled drive axles and a trailing axle, which was mechanically coupled to the laterally movable third drive axle, was chosen for the chassis . This construction, known as the Krauss-Helmholtz frame , enabled optimal arc travel with minimum radii of 60 m and the same travel speed when traveling forwards and backwards. The storage of this trailing frame in an outer frame under the driver's cab also made a generously dimensioned fire box possible .

These locomotives fully met the expectations placed on them, so that the Steyrtalbahn had three more examples built, the last one which deviated significantly from the series after the line was extended to Klaus in 1914. It was analogous with a short smoke chamber the second series of SKGLB machines, but had long water tanks.

The No. 1 was retired after an accident in 1937. At the time of the Reichsbahn, the remaining machines had the numbers DR  99 7831-7835. With the takeover of this line in the state railway operation, the five machines were given the numbers 298.102-106 by the ÖBB . In order to increase the water supply, the water tanks were enlarged several times, at first they were made a little higher and later extended to the front to over the cylinders, these modifications significantly changed the appearance of the locomotives.

The last of them was 298,104 until 1972 in the Steyrtal valley, in 1973 the series was formally retired.

In 1891 four locomotives of the Steyrtal type were ordered for the Mori – Arco – Riva local line . The first three were delivered by Krauss in Linz in 1890, the last in 1892. They were given the names "ARCO", "RIVA", "LAGO DI GARDA" and "PINZOLO" and the numbers 1–4. The 1 came to Italy after the First World War . The 2 was brought to Poland by the Austro-Hungarian Army Railroad , where it stayed and came to a forest railway. In 1941 she came as 395.104 to MÁV in Marosvásárhely, today's Târgu Mureș in Romania . After the end of the war it was in the CFR's inventory as 395.104. The 3 landed as JDŽ 183-001 in Yugoslavia . Finally, the whereabouts of the 4 are not known.

In May 2018, the steam locomotive 764.007 was transferred from the Steyrtalbahn to the Stainzerbahn (Styria). It was originally (like the 764.411R locomotive) built for the Romanian forest railways CFF and later operated for the ÖGEG , but was last parked for over a year.

The Salzkammergut Local Railway (SKGLB) also procured such locomotives. The locomotives 3–5 built for the opening of the Salzburg - Mondsee line in 1891 were still almost exactly the Steyrtal railway type with the long smoke chamber , the engines 6–12 re-ordered from 1893 had a short smoke chamber.

Several copies have been preserved for posterity, some of them operational. The 298.102, which was reactivated in 2004, was rebuilt in the version with enlarged water tanks. It is the oldest locomotive in Austria with a track width of 760 mm and, like the 298.106, is now part of the active stock of the Steyrtal Museum Railway. 298.104 is located on the Ybbsthalbahn mountain route .

Three copies (No. 7, 11 and 12) of the SKGLB were sold to the Steiermärkische Landesbahnen (StLB) after they were discontinued in 1957 , others (No. 4 and 9) were erected as monuments and thus escaped scrapping. Locomotives 5 and 8 remained in Bosnia from 1915, locomotive 5 was acquired by Club 760 in the 1970s . Locomotive 12 is in use today on the Taurach Railway , locomotives 4, 5 and 9 are on display in the SKGLB Museum in Mondsee (the first two are preserved in working order). Locomotive 7 is parked with a U series boiler in the vehicle hall of Club 760 in Frojach.

One of the locomotives of the Mori-Arco-Riva local line, ex Southern Line 40.02, got to Romania after the First World War, was used there by the CFR until 1975 and now runs on a park railway in the Omaha Zoo in the USA .
