The 5081 series diesel multiple unit of the ÖBB is the Austrian version of the Uerdingen rail bus .
history
SGP (Simmering Graz Pauker) in Graz developed an Austrian variant of the rail bus in 1954. This pre-series including the two trailer cars was taken over by the ÖBB in 1956, but there was no series production of these 5080 series light railcars . Instead, a few years later the ÖBB decided to purchase three Uerdingen rail buses on a trial basis , which had previously proven themselves in Germany (as DB VT 98 and 798), but also on the Graz-Köflacher Eisenbahn . In 1964 5081.01-03 (Uerdingen) were delivered; These German copies can be recognized by diamond-shaped factory plates on the fronts. To support the Austrian economy, both the Jenbacher Werke in Tirol (5081.11-22, built in 1965) and SGP Vienna (different colors of the seat covers of the train driver's chair) (5081.51-65 built in 1965-67) received the order for the delivery of a license-made one Series. There were deviations in several details compared to the German original. The ÖBB 5081 are equipped with translation windows ("half windows"), the doors extend further down (lower entry edge) or z. B. Wipers and headlights have been optimized.
In addition, the following sidecars were purchased: 7081.01–03 (Uerdingen, built 1964 - conversion 1974–75 to control car 6581.01–03), 7081.04–09 (built 1965), 7081.11–27 (Jenbach, built 1966–67) and 7081.51–54 (SGP-Vienna, year of construction 1967). In addition, there were control cars 6581.11–20 (Jenbach, built 1965–66) and 6581.51–67 (SGP-Vienna, built 1967).
The drive concept was extraordinary. There were two horizontal six-cylinder Büssing diesel engines with 150 hp each. These each drove a single axle via a mechanical six-speed gearbox. Due to the low vehicle weight, good acceleration rates could be achieved compared to steam locomotives despite the low engine power. In practice, 1 or 2 trailers could be used with a railcar. A freight wagon was very rarely added.
After the staff representatives refused to agree to a planned and inexpensive one-man operation (the train driver also sells tickets), instead of rationalizing the operation on branch lines, the vehicles were also used on main lines with a driver and z. Sometimes one conductor was used per sidecar (there were no crossovers).
The unplanned high point of the use of the 5081 sets designed for branch lines was their use as a high-speed railcar between Linz and Selzthal. Further areas of application existed in the area of the train conveyances Wels, Knittelfeld, Villach, Lienz (here as a demanding corridor train Innsbruck - Lienz), Vordernberg, Mürzzuschlag and Wiener Neustadt. Six railcars were retrofitted with additional magnetic rail brakes and exterior mirrors for use on the Erzbergbahn and numbered as 5081.560-565. A battery room was built into this, which connects to the toilet, recognizable from the outside by a ventilation grille instead of the second window; four seats have also been omitted.
The railcars were very popular with passengers because, thanks to their unique design, similar to a bus, they allowed a real all-round view and also offered the opportunity to look over the driver's shoulder. In addition, the backrests of the seats could be folded down in the direction of travel. A disadvantage compared to other types of railcars was the more restless running behavior of the two-axle vehicles and the lower level of passive safety in the event of a collision.
Accelerated by a serious accident on the Schneeberg Railway (head-on collision), the last rail buses were withdrawn from service by 1994 and replaced by the 5047 and 5147 series railcars . Although the 5081s were delivered much later than the DB originals of the 798 series, the plan service ended earlier than in Germany. Some cars were converted into trailers for use with 5047s: four sidecars were designated as 7047 cars with modern seats. The two wagons 7081.24 and 7081.54 became the bicycle transport wagons 7147.001 and 7147.002. The benches and the toilet were removed and suspensions for 30 bicycles were attached. Both the 7047 and 7147 were painted in ivory, blood orange and ultramarine.
Occasionally, the 7081 and 6581 were added to the new railcars as wheeled transport wagons (e.g. Almtalbahn). A further 3 railcars have been used since the withdrawal from planned operation with the number designation 8081 as service railcars, primarily for the route training of train drivers.
Whereabouts
Until December 2010, three rail buses were still in the ÖBB's portfolio as the 8081 series (8081.001, 015, 021, 055) and were used for in-house tours and training trips; they were sold to Austrovapor, ÖGEG and Erzbergbahn. Four copies are in use on the Erzbergbahn, which has been preserved as a museum railway . In addition to the 5081.15, which is operational again (as of September 2013), there are other railcars in the Strasshof Railway Museum .
The railcar 5081 051, control car 6581 055 and trailer car 7081 023 were sold to Germany in 1991. However, there was no reconditioning, so the set came back to Austria. The NÖVOG let the set worked up and painted in gold NÖVOG design, the clothing was planned because on from 2014 Wachau railway use. It has not yet been deployed there, operations are carried out with the 2043.24 and Schlieren car . The set runs every April on the Retz – Drosendorf local railway with 2 pairs of trains each. The 7081.23 sidecar was sold in 2019 to the Zayataler Schienentaxi of the Neue Landesbahn association, where it runs between two X626 draisines as a sandwich set between Mistelbach-Interspar, Asparn an der Zaya and Draisinenalm Grafensulz.
Some vehicles were sold to Germany after decommissioning. These included 5081.003 as one of the three first Uerdingen rail buses delivered, as well as 6581.001, which was converted into a control car in 1974. With 6581.053, they belonged to the Westfälische Localbahn eV Bielefeld until 2015, where they were to be restored to working order and used for museum trips. In 2015 the 3 vehicles were sold to the Friends of Rail Bus eV in Kornwestheim. 5081.003 was refurbished ready for operation and adapted to the color scheme of the DB's VT98. Since May 1, 2016, it has been used for excursions on the Krebsbachtalbahn .
Since 2009 three vehicles have been with the rail bus association in Kornwestheim (near Stuttgart). There are 5081.561 (the VT was retrofitted with an engine brake and additional batteries and renamed as 5081.61), 6581.054 and 7081.017. The color scheme there was adapted to the DB's VT98. The three vehicles are currently carrying a double-sided advertisement for the Stuttgart Wulle brewery.
