Data from "Recent Superheater Locomotives," The Locomotive Magazine, Vol XVIII (14 December 1912), p. 254. See also Litt L11 - 5, 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 Tommy Nilsson's Svenska-lok.se website at Svenska-lok.se, last accessed 20 July 2018. Works numbers were 420-421 in 1908 and 464-465 in 1912.
These modest Moguls served a 30 km (18.6 mi) railway that ran northwest from the city on Lake Hammar to HSssleholm. Kristianstadt, near the very southernmost part of Sweden, lies east of Helsingborg and northeast of Malmo. (Distance from Kristianstadt by way of Hasselholm to Copenhagen by rail was about 170 km (106 miles).)
Data fromLitt L18, one of a series of SJ locomotive diagrams archived by Anders Lundbing on [], last accessed 10 June 2017; and Tommy Nilsson's Svenska-lok.se website at Svenska-lok.se, last accessed 20 July 2018. Works numbers for the CHJ 12-13 were 858-859 in 1907.
These small Moguls were the first superheated locomotives on the CHJ. The dimensions and photographs show an undersized boiler on the heavy frames. Its adoption of superheat at a relatively early time This variant used piston valves measuring 180 mm (7.09") to admit steam to the cylinders.
The CHJ was taken into the Statens Jarnvagar in 1944. The SJ placed the pair in Class L18 and renumbered them 1661-1662, but kept them on the former CHJ metals.. 1661 carried on for another nine years before being withdrawn in 1953. 1662 was then shifted to the Kristianstad - -lmhult service until its retirement in 1956.
