ÖBB Class 1042

The Series 1042 is an electric locomotive of the Austrian Federal Railways. She was in the 1960s a mainstay of the electric railway operations of the ÖBB. From the serial number 1042.531 numerous machines to the series in 1142 were rebuilt in the 1990s.

History

In the 1950s, the electrification of the Austrian route network was already far advanced. The ÖBB required particularly for the southern runway, including the ramp route over the Semmering, new and more powerful locomotives. Due to negative experiences with the six-axis series in 1010 and 1110 on winding ramp routes they wanted to obtain from now on only four-axis machines.

The new locomotives for which the series designation was provided in 1042 should reach a top speed of 130 km / hr. The applied power was approximately 3500 kW hours.

In the years 1963-1977 a total of 257 locomotives were delivered to the ÖBB, the individual series differed in detail. Due to increased demands in fast mode, the maximum speed from the 1042.501 150 km / h was increased.

The first 80 locomotives were delivered in green livery, the other locomotives in blood orange. The green box in the middle of locomotives had a revolving screwed-on aluminum profile, the red locomotives painted decorative lines. Until 1987, the locomotives were repainted green, with the exception of 1042,044.

Technical design

The electrical equipment was developed by the company ELIN, BBC and Siemens, the mechanical part was built by the locomotive factory Floridsdorf which later Simmering -Graz -Pauker Graz belonged. The Series 1042 can be seen as a purely Austrian development. Drive, frame and roof structures are a further development of the Austrian 1046 dar. When driving the best in the 1141 Siemens rubber ring spring drive was changed slightly, the spring elements were behind the arched Vollradscheiben.

Developed by ELIN high-voltage stage controller with 34 selectable speed levels enables a particularly smooth starting of the locomotive. The electric brake is also represented an Austrian redesign: it is a combined regenerative and resistance brake, the braking force reaches more than half the hours pulling force of the locomotive.

The locomotives from 1042.531 received a thyristor BBC resistor brake, but an extension of the roof structure was required.

The first 30 locomotives were Scherenstromabnhmer 1974 were 1042.20 converted to 30 on pantographs. From 1042.31 all locomotives received the same pantograph, with the knee initially showed outward from 1042,531 to the inside.

The car body is supported on a balance beam to the bogie. The locomotive body was load-bearing and took the train to the frame and impact forces. At the bogies massive imaginary as Schneeräumpflüge obstacle deflector were installed. The draw hooks could be advanced pneumatically, to facilitate the disconnection of discharge.

Modifications and improvements

Shortly after the commissioning of the new locomotive type occurred electrical arcing at higher speeds with the engines. The problem could be eliminated by collector treatments and carbon exchange. It came later but the conclusion to install a new engine type.

It came after two new engines for use:

  • An improved engine the origin type, the EM 891
  • The " Gotthard engine ", a Swiss development (EM 910)

Extensive testing with these newly developed engines gave very valuable insights, which were decisive for the future engines. The new motor EM 910 allowed an increase in the power of the locomotives from 890 kW to 1000 kW. Thus it was possible, through a change of gear ratio a top speed of 150 km / h to.

Because of the higher speeds, the electric brake of the locomotive was not sufficient, so the machines 1042.531-707 received a thyristor high- resistance brake.

In the early 1990s began, because Nachlieferungsschwierigkeiten and concerns Dielectric strength developing or verblechen the corner window of the locomotives. This conversion is carried out since 1993 in part repairs. The right entrance door was closed from 1995.

The newer locomotives were fitted with push-pull train 1995-2001 and then performed as a series in 1142. 99 locomotives were equipped with emergency brake from 2002 to 2005.

Whereabouts

With the extensive renewal of the vehicle fleet at ÖBB from about the mid- 1990s through 1042 newly delivered machines of the Taurus family ( ÖBB 1016/1116 ) has been superseded and replaced in subordinate services. As of early 2007, the number 1042 is the oldest electric locomotive type on the standard gauge network of ÖBB and with continued withdrawal only a few pieces available.
