Carlskrona-Vaxso 2-6-0 Locomotives in Sweden


Class Details by Steve Llanso of Sweat House Media

Class 14/L11 (Locobase 20398)

Data from Litt L11-1, one of a series of SJ locomotive diagrams archived by Anders Lundbing on [link], 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 number was 815 in 1906.

Possessing the same power dimensions as other Moguls delivered to several railways during the same period. this CWJ 2-6-0 was the only one built by Nohab (all others came from Motala). Its superheater upgrade resulted in a shorter boiler and a few more flues than the others.

Along with other CWJ Moguls, the 14 was taken into the Statens Jarnvagar and given road number 1562. It was retired in 1957 and eventually scrapped in 1974.

(Inside tube and flue diameters measured 43 and 118 mm, respectively, which led to a tube heating surface area of 66.8 sq m (730 sq ft) and evaporative heating surface area of 74.6 sq m (803 sq ft).


Class 15/L11 (Locobase 20399)

Data from Litt L11-2, one of a series of SJ locomotive diagrams archived by Anders Lundbing on [link], 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 406 in 1908, 419 in 1910, 578 in 1916, and 650 in 1919.

Two years after the CVJ received its first small Mogul from Nohab, Motala began supplying locomotives as well. These were virtually identical to the Cristianstadt-Hasselholm locomotives shown in Locobase 20066.

(Inside tube and flue diameters measured 43 and 119 mm, respectively, which led to a tube heating surface area of 66.8 sq m (730 sq ft) and evaporative heating surface area of 74.6 sq m (803 sq ft).


Class 20/L15 (Locobase 20403)

Data fromLitt L14, one of a series of SJ locomotive diagrams archived by Anders Lundbing on [link], last accessed 10 June 2017; and Tommy Nilsson's Svenska-lok.se website at Svenska-lok.se, last accessed 20 July 2018. Works number was 734 in 1928.

The CVJ was not quite satisfied with its duplicate of the 1918 Christianstadt-Hasselholm Mogul delivered by Nohab in 1926 and shown in Locobase 20402. According to Tommy Nilsson, the drivers proved to be a bit too tall, so the 20 rolled on the 1,600 mm drivers shown in the specs. The boiler and firebox were smaller, too. This engine was rated at 90 kph (56 mph).

When the CVJ merged with the Statens Jarnvagar in 1941, the SJ assigned it its own class ID and gave it the next road number in the sequence.

The L15's smaller size--compared to almost all other superheated 2-6-0s in the SJ--and unique characteristics may have prompted an early retirement in 1954. In reserve for years, it was finally deleted in 1969 and scrapped in 1971.

(Inside tube and flue diameters measured 41 and 119 mm, respectively, which led to a tube heating surface area of 66.93 sq m (741 sq ft) and evaporative heating surface area of 75.95 sq m (818 sq ft).)
