Data from Litt. L11-4, 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 were 480-482 in 1912.
This trio of small Moguls was identical to the two SaNJ L7s described in Locobase 20390 and preceded them into service by two years. Their smaller drivers marked them as the new railway's freight power. Like most of the L11 2-6-0s operated by private railways in Sweden, these engines were taken into the Statens Jarnvagar in 1940.
All were retired and placed in standby reserve in 1960.
(Inside tube and flue diameters measured 43 and 119 mm, respectively, which led to a tube heating surface area of 68.55 sq m (738 sq ft) and evaporative heating surface area of 77.30 sq m (832 sq ft).)

Locobase 20401 describes the freight Moguls that helped the SaNJ in its opening years. Two years after they entered service, these variants repeated the design but rolled on 200 mm (7.9") taller drivers that allowed an 85 kph (53 mph) maximum speed.
