Uddevalla - VSnersborg - Herrljunga 2-6-0 Locomotives in Sweden


Class Details by Steve Llanso of Sweat House Media

Class 16/L6 (Locobase 20395)

Data from Litt. L6, 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. See also Rolf Sten's history of the UWHJ/UVHJ at [link] (thanks to Google Translate); and the English-language history of Vanersborg at [link], both, last accessed 20 July 2018.

VSnersborg lies at the very southwestern end of Sweden's Lake Vanern, about 85 km () north east of Gothenburg. The first impetus for a railway was dissatisfaction with the canal connecting the two. Shippers complained that the travel time between VSnersborg and Gothenburg was the same as transit time between Gothenburg and England. Later, the railway extended a line southeast from VSnersborg to Herrjunga to compete for the oat-grain trade generated by farms on the Vara plain.

Five small Moguls were the first standard-gauge locomotives bought by the UVHJ after gauge widening from 1,219 mm (48") was completed in 1899.

In 1908, the Borss - Herrljunga railway bought a single superheated Mogul (road #20) based on the earlier saturated-steam engines. A year later, the UVHJ returned to Nohab for more 2-6-0s, they ordered a superheated variant in 1909, which entered service as the 16. Apparently satisfied with the upgrade's performance, they bought another two in 1917 (17-18), and superheated the 14.

The design's maximum speed on the UVHJ was 80 kph (50 mph).

The 18 was the last new locomotive purchased by the UVHJ, although the railway remained independent for another 23 years before the Statens Jarnvagar (SJ) absorbed it in 1940. At that point, the four superheated 14-17 and the BH Mogul were placed in class L6. 14 and 16 were withdrawn in 1943 and scrapped a year later. Ex-BHJ 20 remained in service until 1952 and was scrapped in 1956. 18 retired in 1956 and was cut up a year later. 17 enjoyed the longest life, remaining on the roster until 1964.

(Inside tube and flue diameters measured 42.5 and 122 mm, respectively, which led to a tube heating surface area of55.65 sq m (599 sq ft) and evaporative heating surface area of 68.8 sq m (741 sq ft).)
