Source-derived summary

The SJ Class Ra (or Rapid) is an electric locomotive operated by Swedish State Railways (Swedish: Statens Järnvägar, SJ). Ten units were built by ASEA, two in 1955 and eight in 1961. Ra was used on express trains until the 1990s.

History

During the 1940s SJ had a need for lighter and quicker locomotives for their express trains. In 1953 two bogie-locomotives were ordered from ASEA. Inspiration for the appearance came from North America, with round shapes and a bulldog nose. The two first units were successful and SJ ordered additional eight units from ASEA, delivered in 1961. The Ra name follows SJs standard naming practices where "R" stands for a fast electric locomotive and the "a" denotes that its the first variation of the series.

They were capable of 150 km/h service but never reached more than 130 km/h in revenue service, mainly on the Stockholm - Göteborg line and Stockholm - Oslo line. During the 70s and 80s they were replaced on faster routes by newer locomotives such as the Rc series. The last two trains left the fleet in 1996, in their later years they mainly pulled exposition trains, for example before the Swedish EU membership referendum in 1994.

Editorial summary

Begin with the source’s own compact description: “SJ Ra” is locomotive class. The dossier treats that line as a proposition to test through locomotive and class, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1955, 1961, 1953, 1996—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, locomotive and class is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “locomotive class” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 21, 2026. The linked authority identifier is Q595856. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1955, 1961, 1953 and 1996.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
