The series SJ Rb were six pre-series - electric locomotives for heavy haul service at Statens Järnvägar (SJ) in Sweden . The individual series of the SJ Rc series, which were delivered from 1967, were developed from the knowledge gained .
Technical background
Six copies of the pilot series were produced in different versions and placed in the sub-series Rb1, Rb2 and Rb3. They were used to test technical innovations.
The procurement was based on the SJ's knowledge that the 333 old D locomotives built since 1925 must be replaced. There were also employment policy reasons, as ASEA suffered from a lack of orders and was supposed to gain experience with the construction of AC locomotives.
Diodes were manufactured as early as the 1920s . At the time, this was so well developed that it could be used in power electronics . The first thyristors hit the market just a few years before the locomotives were built . The developers did not consider these to be sufficiently mature to use them in the construction of the Rb series .
The Rb locomotives were also used as models for locomotive sales and licensing abroad. So procured Romania ( CFR : about 1000 pieces CFR series 060 EA ) and Yugoslavia ( JŽ : 103 pieces JŽ-461 series ) a six-axle variant, some of which were built under license. The Norwegian El 15 locomotive , now used by Hector Rail as the 161 , has a structure that is partly based on the Rb .

In contrast to the later production locomotives, the pilot series had slightly lower windshields and a smooth outer surface. They were equipped with the current collector type LLXJE 135.
SJ Rb1
The two locomotives of the Rb1 series were given the numbers Rb1 1001 and Rb1 1002 . They were built by ASJ and ASEA as rectifier locomotives and equipped with high voltage regulation. The voltage was rectified with diodes .
The locomotives were powered by series-wound motors, which were operated with DC voltage instead of the single-phase series-wound motors used in earlier locomotive constructions . These two locomotives became the model for export because they offered the best solution for Romania and Yugoslavia (except Slovenia) with the existing line voltage of 25 kV / 50 Hz. They were planned for export right from the start, and the locomotive body received the narrower international profile of 3,100 mm.
The Rb1 1002 was parked there after its use in Ånge until 1976 and scrapped in 1985.
SJ Rb1T
When the use of thyristors was possible, the Rb1 1001 was converted into a thyristor locomotive in 1965 and called the Rb1T .
The thyristors allowed precise and variable control of the motor current so that the train driver could accelerate the locomotive to the desired speed without switching between different driving modes. In addition, there were other advantages: higher pulling force, less risk of slipping and less maintenance.
This locomotive became the prototype for the Rc series . After being used in Ånge until 1974, it was parked there and scrapped in 1985.
SJ Rb2
The two locomotives of the Rb2 series were given the numbers Rb2 1003 and Rb2 1004 . They were built by ASEA and Nydqvist och Holm .
These locomotives had the same type of controls and motors as the Ma and F series . This was a voltage regulation on the high voltage side and AC motors from the previous series. This version did not get along as well with the line voltage of 25 kV / 50 Hz as it was used in the export market. The locomotives worked well, but the diode technology of the Rb1 series was more interesting and so this version did not find supporters in Sweden or abroad. Both locomotives were therefore taken out of service after a long period of storage , the Rb2 1003 in June 1975 and the Rb2 1004 in June 1976.
The Rb2 1003 was used as a counterweight for the rail renewal train in 1984 and, like the Rb2 1004, was scrapped in 1985.
SJ Rb3
The two locomotives of the Rb3 series were given the numbers Rb3 1005 and Rb3 1006 . They were built by ASEA and Motala Verkstad .
Technically, they were identical to the Rb2 series and only differed in the manufacturer of the mechanical part. There were no successors for this series either. Both locomotives were taken out of service after a long period of storage , the Rb3 1005 in December 1975 and the Rb3 1006 six months later. Rb3 1006 was scrapped in 1976.
Rb3 1005 was officially assigned to Banverket in 1989 , because parts of the locomotive had been used years earlier for the prototype of a new rail conversion train .
Rail renewal train
The bogies of the Rb3 1005 were used for a rail conversion train that SJ constructed in the 1980s. Engineer Hamrin from Lesjöfors and Lennart Borup from SJ BAUR (Banavdelningens Rationaliseringskontor) were responsible for this . Rb3 1005 was converted into a car for this train in January 1978 in the test workshop in Falköping , which was scrapped in August 1990. The last parts of the locomotive were sold to Gotthard Nilsson Återvinning AB , Nässjö , and scrapped in November 1996.
The train was tested on the Västra stambana and produced good results on a straight line. After it got stuck in the curves at Kåhög between Partille and Jonsered , it was no longer used. This train has now been scrapped.
