Nassjo-Oskarshamn 2-6-0 Locomotives in Sweden

Class 127/L4 (Locobase 20392)

Data from Litt. L4, 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. Works number was 502 in 1913.

This relatively high-drivered Mogul repeated Motala's 1908 engine, which was delivered to the Ostra Centralbanab described in Locobase 20391) Like many Swedish Moguls, this locomotive had the Krauss-Helmholz bogie, which combined the truck axle and the leading driving axle. It resembled the L class, but its latter drivers made it even more suitable for the NOJ's passenger service, where its maximum speed was set to 90 kph (56 mph). It came to the SJ in 1946.

The 1777 was withdrawn in 1956.

(Inside tube and flue diameters measured 44.5 and 125 mm, respectively, which led to a tube heating surface area of 86.95 sq m (936 sq ft) and evaporative heating surface area of 97.05 sq m (1,045 sq ft)).

Class 33/L5 (Locobase 20393)

Data from Litt. L5, 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. Works numbers were 1878-1879 in 1931.

Eighteen years after the NOJ took delivery after its #27 (Locobase 20392), Nohab sent two of the last four new Moguls to be supplied to a Swedish railway. The design offered several differences from the 1913 engine, including the inside radial valve gear, smaller tubes, much more superheater area, less cylinder volume, and smaller drivers. Inside piston valves measured 200 mm (7.87") in diameter.

The pair joined the SJ in 1946. They hauled their last trains in eastern Smsland and on Mjölby - +deshög service southwest of Stockholm and Linkoping before being withdrawn in 1960.

(Inside tube and flue diameters measured 39 and 125 mm, respectively, which led to a tube heating surface area of 89.4 sq m (962 sq ft) and evaporative heating surface area of 98.8 sq m (1,063 sq ft)).

Class E7/L29 (Locobase 20796)

Data from Litt. L29, 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. Works numbers were 377 in 1907, 437 in 1910, and 577 in 1916.

The first of the three small Moguls delivered to the NOJ had lower heating surface areas than did the latter two. The most significant was the superheater, which was delivered with an installation measuring 21.75 sq m (234 sq ft). (Inside tube and flue diameters measured 44.5 and 125 mm, respectively, which led to a tube heating surface area of 71.72 sq m (772 sq ft) and evaporative heating surface area of 81.01 sq m (872 sq ft)).

Inside cylinders used piston valves of 200 mm (7.87 in) diameter.

The three engines remained in service into the 1950s. 1781 was idled in 1960, but held in reserve as an emergency locomotive. It went to the scrapper in 1967.1782 was idled in 1962, dismantled in 1963.1780 somehow lasted into the 1970s before being withdrawn in 1974 and scrapped in 1976.
