The 1042 series is an electric locomotive of the Austrian Federal Railways . Since the 1960s, it has been an important pillar of the ÖBB's electrical rail operations. Starting with the serial number 1042.531, numerous machines were converted to the 1142 series in the 1990s .
history
By the 1950s, the electrification of the Austrian route network was well advanced. The ÖBB needed new and more powerful locomotives , especially for the southern runway , including the ramp route over the Semmering . Due to negative experiences with the six-axis series 1010 and 1110 on winding ramp routes, from now on only four-axis machines were wanted.
The new locomotives, for which the series designation 1042 was intended, should reach a top speed of 130 km / h. The hourly output to be applied was around 3500 kW.
Between 1963 and 1977 a total of 257 locomotives were delivered to the ÖBB, the individual series of which differed from one another in detail. Due to increased demands in express train operations, the top speed was increased from the 1042.501 to 150 km / h.
The first 79 locomotives were delivered in green, the rest of the locomotives in blood orange. The green locomotives had a circumferential screwed aluminum profile in the middle of the box, the red locomotives had decorative lines painted on them. By 1987 the green locomotives were also repainted, with the exception of the 1042.044.
Technical design
The electrical equipment was developed by ELIN , BBC and Siemens , the mechanical part was built by the Floridsdorf locomotive factory , which later belonged to Simmering-Graz-Pauker Graz. The 1042 series can be seen as a purely Austrian development. Running gear, frame and roof structures represent a further development of the Austrian 1046. The Siemens rubber ring spring drive, tried and tested in the 1141, was slightly modified as the drive, the spring elements were located behind the curved solid wheel disks.
The high-voltage step switch developed by ELIN (rotary selector with main and secondary brush as well as the "turner") with 34 selectable speed steps enables the locomotive to start up particularly smoothly. The electric brake was also a new Austrian design: It is a combined utility and alternating current resistance brake, the braking force of which is more than half an hourly pulling force of the locomotive.
The locomotives from 1042.531 onwards received a thyristor-controlled BBC resistance brake (separately excited direct current high-performance resistance E-brake). An extension of the roof structure was necessary for this.
The first 30 locomotives received pantographs, in 1974 1042.20 to 30 were converted to single-arm pantographs. From 1042.31 onwards, all locomotives were given single-arm pantographs, with the knee pointing outwards initially, and inwards from 1042.531 onwards.
The car body is supported by a weighing beam on the bogie. The locomotive structure was load-bearing and took over the tensile and impact forces with the frame. Massive track clearers, also intended as snow plows, were attached to the bogies. On some locomotives, the tow hooks could be pneumatically advanced to facilitate uncoupling by relieving the load.
The electric motors are based on plans by Robert Stix .
Modifications and improvements
Shortly after the new type of locomotive went into operation, the motors began to experience electrical flashovers at higher speeds. The problem could be eliminated by collector treatments and carbon changes. However, it was later decided to install a new type of engine.
Two new motors were then used:
- An improved engine of the original type, the EM 891
- The "Gotthard engine", a Swiss development (EM 910)
Extensive tests with these newly developed engines yielded very valuable findings, which were decisive for future engine construction. The new EM 910 engine made it possible to increase the power of the locomotives from 890 kW to 1000 kW. It was possible to achieve a top speed of 150 km / h by changing the gear ratio.
Due to the higher speeds, the electric brakes of these locomotives were no longer sufficient, so the machines 1042.531-707 were given a thyristor-controlled high-performance resistance brake .
At the beginning of the 1990s, the corner windows of the locomotives were expanded or sheeted due to delivery difficulties and concerns about dielectric strength. This conversion has been carried out since 1993 with partial repairs.
From the mid-1990s, the locomotives were visually noticeably redesigned in addition to the technical overhaul in the course of the main repair due after partial repair 4. The headlight consoles with the large headlights and the tail light above were exchanged for smaller ones based on the ÖBB 1044 with a side tail light. The sliding handles have been rearranged and the sides of the sheet metal have been shortened. In addition, the locomotives have been repainted in the new Valousek design with umbra gray glasses on the front windows. From 1995, in the course of this work, the right entry door for each driver's cab was laminated in order to avoid drafts in the driver's cab. From the end of 1995, the conversion to series 1142 was also carried out as part of this HG repair . The third tail light was removed from now on, including the console. The conversion to the 1142 series was not only carried out when the HG was repaired, but also when partial repairs were due. This resulted in locomotives of the 1142 series in a blood orange design with large headlights or in the Valousek design with four doors. The tail light was removed and the console closed with a metal plate, but not completely removed. Between 2002 and 2005, 99 locomotives were equipped with an emergency brake override, for example in order to be able to leave the tunnel or bridge in a passenger car in the event of a fire despite the emergency brake being pulled.
Not only did a large part of the number group 1042/1142 531 - 664 undergo the visual changes in the course of the HG repair, but also some locomotives from other series due to accident repairs in the 1990s. This applies, for example, to 1042 008, 011, 018, 036, 038, 051, 059 and 508, which have also been optically adjusted in the HW Linz.

With the extensive renewal of the ÖBB fleet from around the mid-1990s, the 1042 was replaced by newly delivered machines from the Taurus family ( ÖBB 1016/1116 ) and pushed into subordinate services. As of the beginning of 2007, the 1042 series is the oldest type of electric locomotive on the ÖBB's standard gauge network and, with continued decommissioning, only available in small numbers.
