The electric locomotives of the SJ Ö series were Swedish accumulator locomotives that were purchased by Statens Järnvägar from 1926 . This was the time when the Swedish rail network was electrified on a larger scale. The locomotives had pantographs , rectifiers and batteries in order to be able to use them as construction locomotives on routes on which there was no overhead line. The electricity was drawn from the contact line .
Series Öa
The first two locomotives were built in 1926. They were biaxial and had the cab in the middle. They did not prove to be suitable for shunting traffic and were mainly used for the overhead line assembly trains.
Zö series
As part of a re-drawing, the locomotives were given the numbers Zö 100 and Zö 101 in 1929.
The Zö 100 was in use until 1960 and was scrapped in Vislanda in the same year, the Zö 101 was parked in 1963 and scrapped in Notviken in 1967.
Series Öb
In the early 1930s, SJ ordered eight more powerful locomotives. These were biaxial and did not meet expectations. They were withdrawn from circulation between 1963 and 1970 and scrapped between 1964 and 1970.
Series Öc
The next series was built based on experience as a bogie locomotive. The twelve locomotives delivered by ASEA in 1935 and 1936 were the first bogie locomotives in Sweden. As in the previous series, the driver's cab was arranged in the middle. The batteries were housed in one of the two fronts, the engines were in the other.
The batteries with 360 cells connected in series were charged via a charger when the locomotive was used in catenary operation. The traction current for the motors was taken from the batteries.
Öc 396 was used for rectifier tests from 1960 to 1963, after which it was shut down and scrapped in 1964. The rest of the series was parked with two exceptions from 1967 and scrapped until 1975. Öc 491 was transferred to the SJ's official vehicle inventory in 1981 and was given the number Qaz 9451116. After being shut down in 1983, it became a reserve locomotive for the Swedish Railway Museum in 1988; it was scrapped in Grängesberg in 2003. Öc 395 also became a service vehicle in 1981 as Qaz 9440076, was given the new designation Qzg 9440076 in 1986 and was handed over to the Railway Museum in 1987.
Öd series
The strongest series followed in the 1940s. These locomotives could be driven as normal electric locomotives either with batteries or via overhead lines. In addition to the electrification work, they were mainly used in shunting operations. Here it was possible to drive on sidings without overhead lines in battery operation.
The first locomotives were shut down in 1970. After the series Öa and Öb had been retired, further locomotives were transferred to the service vehicle fleet and only used for track construction.

The last locomotive in normal service was parked in 1981 and scrapped in 1982.
Whereabouts
In the early 1990s there were advanced plans for Öd locomotives that were to take over the loading of wagons onto the rail ferries at the new Helsingborg C station . Preparations for a decommissioned locomotive began. However, it was never completed. The Z68 series took on this task .
The SJ had no successors for the locomotive type. It was cheaper to use diesel locomotives instead of maintaining the heavy and maintenance-intensive accumulators.
Two locomotives have been preserved: Öc 395 at the Sveriges Järnvägsmuseum in Gävle and Öd 450 at the Malmbanans Vänner museum company.
