The BBÖ 2041 / s was a series of diesel-electric narrow gauge - baggage railcars of BBÖ . In practice, however, they were used almost exclusively as diesel locomotives .

history

2091.02 was given the original green paint again, here in Alt Nagelberg (2015)

This series was a more powerful further development of the diesel-electric BBÖ series 2040 / s built in 1934 . The vehicle was designed as a light luggage railcar. Luggage was supposed to be loaded in one of the two stems, making it unnecessary to carry a separate baggage cart. Hardly any use was made of it in practice; instead, the vehicles were used as locomotives.

The first seven locomotives were delivered in 1936/37 by the Simmeringer Maschinen- und Waggonbaufabrik (mechanical part) and Siemens-Schuckert (electrical part). From 1938 to 1940 another five followed, which had already been ordered by the Deutsche Reichsbahn . The latter differed in details from the first delivered (see table). The DR (B) classified the twelve vehicles as motor coaches 137 332-137 343. During the Second World War , the DR (B) converted seven locomotives to gas propulsion due to a lack of fuel; she turned the others off. After 1945 the vehicles were dismantled or reactivated.

With the exception of the Steyrtalbahn and the Vellachtalbahn, the locomotives were used on all ÖBB narrow-gauge lines with a gauge of 760 mm. The ÖBB gave them the designation 2091.01-12 from 1953 , with the leading number 2 again classified as a locomotive.

technical description

The weight of the locomotive is carried by four axles. The two central axles are rigidly mounted and driven. In addition, there is a Bissel-type running axle on each side. This structure ensures a particularly smooth and stable run even through arches. Under the front of the engine there is an R8 diesel engine that drives a generator. The direct current produced here is fed into the two traction motors that drive the two central axles.

In order to be able to heat the cars with steam, a diesel-fired steam boiler was originally housed in the driver's cab. When the vehicle fleet was equipped with Webasto heating, the steam boiler could be omitted. It was subsequently removed from all 12 locomotives. Only the missing second driver's cab window on the luggage compartment side of some locomotives still indicates the time of the steam boiler.

In order to enable one-man operation, it was necessary to constantly check the driver's ability to react. A dead man's system was therefore installed. The traction lever had to be constantly pushed forward against a spring force. When this lever reached the zero position, this system had to be operated by pressing a button. If the staff - for whatever reason - no longer actuate the traction lever while driving and do not press the dead man's button, an acoustic warning signal sounds after 75 m. After another 75 m, an emergency brake is initiated.

Conversions

In addition to the modifications already mentioned, various modernizations were carried out. From 1963, the steam boilers for train heating were expanded because the wagons were equipped with Webasto heaters. In return, Webasto devices were installed in the locomotives to preheat the cooling water.

WSV 2091.02, recognizable the original front of the luggage compartment

In the 1970s, new noise protection regulations meant that sound insulation had to be installed in the locomotives, as measurements in the driver's cabs had shown that the limit values ​​were exceeded. In 1979/80, in addition to soundproofing, the luggage compartment of the 2091.09 was replaced by a lower front structure in which some technical equipment could be found. Furthermore, a SIFA pedal was installed and the drive switch was modified so that it clicks into place and does not have to be held against a spring, which makes the work of the train driver much easier.

In the 1980s and 1990s, the look of the luggage compartment of the 2091.010 and 2091.011 was changed: the step at the top signal was removed and adjusted to the height of the rest of the luggage compartment. This means that the distinctive step has been omitted.

In 1992, the same technical changes were made to the 2091.011 as to the 2091.09 (SIFA, equipment cabinet instead of a luggage compartment, more ergonomic arrangement of the controls). Visually, nothing changed except for the retrofitted tail light. The shape of the (former) luggage compartment remained unchanged.

Coloring

Originally, the vehicles were painted the pine green color of the passenger cars. At the end of the 1960s they were painted in blood orange and ivory, and later they were only painted in blood orange. The 2091.02 was the only ÖBB-2091 to be painted in the so-called “Valousek design” (named after the creator of this color scheme at ÖBB) with a beige band and gray “glasses” around the driver's cab window. In the mid-1990s, individual copies were painted traffic red.

Whereabouts

2091.07 at Heidenreichstein on the Waldviertel narrow-gauge railways
2091.10 as 199 030 of the Döllnitzbahn in front of the locomotive shed in Mügeln

In 1973 the 2091.06 was the first locomotive of this series to be retired after an engine fire. From 1988 some locomotives were sold. In 1992 the 2091.05 retired after an accident. The last four machines (2091.02, 07, 09 and 11) came to the "ÖBB Erlebnisbahn" in 1998, but some of them were sold on. Several of the vehicles received are ready to drive.

  • 2091.01 was painted green by the Austrian Society for Local Railways after all usable spare parts had been removed and initially erected as a memorial at the Lunz am See train station , where it was scrapped in 2013 after advanced dilapidation.
  • 2091.02 is privately owned and received a general inspection including a return to its original state (without steam heating). It is used on the Waldviertel narrow-gauge railways in front of the special trains of the WSV ( Waldviertel narrow-gauge railway association ). As of June 2011, it was in Zell am See, where various repairs (replacement of a drive motor) were carried out.
  • 2091.03 is owned by Club 760 on the Taurachbahn and has been painted in blood orange and ivory. It is currently located at the Pinzgaubahn .
  • 2091.04 is a spare parts donor at the Bregenzerwaldbahn .
  • 2091.07 is owned by the Waldviertler Schmalspurverein (WSV) and has been waiting for a defect to be reconditioned for several years.
  • 2091.08 is in use at the Bregenzerwaldbahn.
  • 2091.09 is owned by the Waldviertler Schmalspurverein (WSV) and is based on the appearance of the 1980s. It runs most of the construction and special trains between Heidenreichstein and Altnagelberg.
  • 2091.10 (now 199 030) was sold to the Döllnitzbahn and re-gauged to a gauge of 750 mm. After the overhaul at BMS Stahlbau in Ostritz , it has been in use again since 2010. It currently has a paint scheme based on the DR scheme.
  • 2091.11 is owned by Club Mh.6 and housed in the heating house Obergrafendorf on the Mariazellerbahn .
  • 2091.12 was also re-gauged to 750 mm and initially sold to the Öchsle narrow-gauge railway , from where it came to the Döllnitzbahn (199 031 there). The two locomotives located in Saxony have now received several new paints. 199 031 were initially parked after an accident or after the deadline had expired. At the end of 2007, the 199 031 was transferred to Ostritz for a general inspection, where it was painted according to the DR color scheme. It has been operational again since July 2008.
