Data from Litt J, one of a series of SJ locomotive diagrams archived by Anders Lundbing on [], last accessed 10 June 2017 (Snabcon AB advertised its tools for mounting RJ45 connectors on bundled cables.) and Olavia Hokas's Swedish Steam website at [
], first accessed 21 January 2006 (most recently 29 April 2018); and Tommy Nilsson's Svenska-lok.se website at Svenska-lok.se, last accessed 5 May 2018. Works number was 1931.
Nilsson's descriptions says that Beyer Peacock delivered a dozen of these small four-coupled leading engines for passenger work. Normally, all of the class would have been discarded well before the SJ acquired a single example in 1948. But the 29 had moved from main-line service to hauling an inspection train and thus was still available.
Within six years, however, the 1821 was scrapped and its boiler sent to the Prins August museum.
