NSB 2-4-0 Locomotives in Norway

Class Class 1a (Locobase 6086)

Data from:

Svein Sando's Railway Site [] (9 June 2004)--(Later link: The Semaphore, accessed for link update 10 July 2022.)--and the Jernbane (Iron Road) site [] (June 2004).

This is the tank version of the Class 2 that arrived in the same year. According to Sando, the last of these little loks was withdrawn in 1915.

Class Class 2 (Locobase 1725)

Data from:

Svein Sando's Railway Site [] (9 June 2004)--(Later link: The Semaphore, accessed for link update 10 July 2022.)-- and the Jernbane (Iron Road) site [] (June 2004).

Began passenger service on the Kongsvinger line; later operated over most of the main lines in Norway. According to Sando, the last of these locomotives was withdrawn in 1920, 58 years after delivery.

Class Class 3 (Locobase 6101)

Data from:

Svein Sando's Railway Site [] (9 June 2004)--(Later link: The Semaphore, accessed for link update 10 July 2022.)-- and the Jernbane (Iron Road) site [] (June 2004).

A few years newer than the 3 class 2 engines and quite a bit bigger, but a solo effort apparently. Still, it remained in service until 1916.

Class Class 5 (Locobase 6103)

Data from:

Svein Sando's Railway Site [] (9 June 2004)--(Later link: The Semaphore, accessed for link update 10 July 2022.)-- and the Jernbane (Iron Road) site [] (June 2004).

Looks like a repeat of the Class 2, but a slightly larger boiler, heavier tender, and a 60 km/h (31 mph) speed rating, up 10 km/h (6.2 mph) from the Class 2. In any case, one of the smallest 2-4-0s of the time.

Remained in service until 1917.

Class Tryggve (Locobase 12393)

Data from "Norwegian Rolling Stock," Engineering, Vol 10 (11 November 1870). p. 348 and Charles Henri Couche (translated by J Edwards Wilson), Permanent Way Rolling Stock and Technical Working of Railways: Rolling stock (London: Dulau & Co, 1878), pp. 453-454. See also Frank Stamford's report on his 2008 visit to the Norwegian Railway Museum at [], Works numbers were 704-705 in 1866; 814 in 1867; 836-837 in 1868; 989-993 in 1870; 1105-1109 in 1871; 1316-1321 in 1873; 1399-1402 in 1874; 1581-1582 in 1875; 2249-2250 in 1882.

Stamford notes that Carl Pihl, the Norwegian engineer who developed the 3 ft 6 in gauge concept in Norway, struggled for a while to find the right locomotive design for the first railways. He and Charles Frederick Beyer "...came up with a 2-4-0T locomotive with leading Bissell truck, sloping cylinders and compensating beams between the driving axles."

Engineering describes a tank carriage often coupled to these engines. The carriage was essentially an auxiliary tender that carried a tank containing 162 US gallons. Water flowed directly into the engine through a pipe. (Locobase isn't sure of the destination--was it the boiler or, more likely, the tanks mounted on the locomotive?)

The design proved very successful. Its modest top speed of 55 km/h (34 mph) suited the traffic demands and the Bissell truck tracked truly over the light rails. The Engineering
