Data from Litt W2 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 numbers were 704-706 in 1923.
Nilsson says that the Oxelösund-Flen-Westmanlands (later TGOJ) bought eight of this wheel arrangement and that two more were bought by the Ystad - Eslövs JSrnvSg (YEJ 4, 5) and two by the Landskrona - Lund - Trelleborg (LLTJ). Locobase cannot confirm that all twelve used the same specifications. In any event the LLTJ sold one of its engines to the TGOJ and one to the Kalmar.
Ultimately the state railway (SJ) took over the KJ Sc 18 (1940) and YEJ's 4 and 5 (1941) and put them on lines serving Malmö - Ystad and Alvesta - Kalmar / Karlskrona.
1620 was retired first in 1962 followed by the other two in 1967.
