Gavle-Dala 2-6-0 Locomotives in Sweden

Class G/L 1 (Locobase 2732)

Data from Eric V Snall, "Recent Swedish Locomotives", The Locomotive Magazine, Vol VI (August 1901), p. 139. See also"GSvle - Dala JSrnvSgar - GDJ. Anglok" at Tommy Nilsson's Svenska-lok.se website at Svenska-lok.se, last accessed 21 June 2018. Works numbers were 525-528 in 1899.

A long-wheelbase Mogul using the Golsdorf system of compounding. For a long time, Locobase couldn't identify the railway, the construction date, or the engine's history. Then information from Tommy Nilsson's site persuaded him that the original British correspondent had given the railway's name as "Pefle-Dala" by mistake. (Some Swedish sources use "Gefle Dala".)

In addition, the writer described the leading pony truck as an "Adamson", most likely meaning an Adams truck. The G class's original configuration featured an inside link motion with rocker arms operating the outside slide valves. A large steam dome perched over the middle driving axle and a smaller sand dome sat over the lead axle.

Like many Continental railways, the GDJ took its time converting compounds to simple expansion. This quartet was modified and superheated in 1928 at which point they were reclassed L3 and renumbered 38-41; see Locobase 20397.

Class L/L30 (Locobase 20797)

Data from Litt. L30, 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 21 June 2018.

Built by NOHAB in 1894 and 1896 (works numbers 401-404 and 450), this Mogul quintet received new boilers topped by a bread-loaf dome that held both the steam dome and sand box. 33-34 were first in 1925 with 35-37 updated in 1932.

The entire class went on the Statens Jarnvagar roster in 1948 as L30s and new numbers 1860-1864. Locobase suspects that 1861 had suffered some sort of casualty as it was struck in 1951 and scrapped in 1952. The other continued on until 1862 left the roster in 1963 followed by the other three in 1964. 1864 was scrapped in 1965, the rest in 1966.

(Inside tube diameters measured 48 mm, which led to a tube heating surface area of 85.60 sq m ( 932 sq ft) and evaporative heating surface area of 95.64 sq m (1,029 sq ft)).

Class L3/L16 (Locobase 20397)

Data from Litt. L16-2, 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 21 June 2018.

Locobase describes the four two-cylinder Golsdorf-system compounds that constituted the first class of locomotves on the GDJ.
