Class 24b Nr. 236 in action on a model railway.

The prototype:

In 1909 the Norwegian State Railways (NSB) invested in a new type of goods engine, primarily for the Randsfjord and Gjövik lines. The Class 24 was a development of the Classes 19 and 22 was built in several sub-classes: 24a (2-cylinder wet steam compound), 24b and 24c (2-cylinder superheated simple expansion) and 24d (also 2-cylinder simple expansion superheated). The Class 24b was built by Thune in 8 examples and was used by the NSB until the end of steam in 1969-70. Despite their low speed limit of only 45 kph (28 mph) these engines were very popular and well functioning. They provided a good tractive effort going uphill even on lines which only permitted low axle loads.

Some technical data:

The model:

Type 24b, as it is called in Norwegian, is an ideal engine to use on a model railway. It is relatively small, but powerful, and has a speed register very well suited to the relatively short distances on the average pike. Our model, which is completely hand-built in brass, represents a typical post World War II version of the locomotive. Enclosed with each model is a set of signs suitable for several individual engine identities. The flywheel equipped Swiss precision motor is placed in the tender. A drive system with ball bearings transmits the power to the third coupled axle and from there through the prototypically linked coupling rods to the other axles. The gear ratio chosen gives the locomotive extraordinary smooth running characteristics at speeds up to a scale 60 kph (37 mph).

The model is characterized by

• Exact scale 1:87
• 2-rail DC with current collection through 16 wheels
• May be equipped with digital control system / decoder
• Simulated 2-cylinder Walschaert steam machinery
• Cab with detailed interior and removable roof (screw fastening)
• Detailed smokebox interior and smokebox door which can be opened
• Glazed windows
• Drive system with ball bearings and exceptionally fine slow speed performance
• All axles sprung
• Wheel rims made of stainless steel with RP 25 flanges
• Minimum curve radius 500 mm
• Sprung couplers and buffers
• Alternative number plates and decals enclosed
• Realistic running characteristics 0-60 kph (0-38 mph)
• Exchange drive wheel set with rubber tire available
• Original Brimalm spare parts kept in stock
• Five year technical warranty.

"Museum" version as running today on preserved railway

The museum version is now sold out.

Versions with smoke deflectors

Versions with norwegian type or Witte german type smoke deflectors are available from stock, as is the standard version without smoke deflectors.

Locomotive in weathered condition

We offer this and other Brimalm locomotives in factory weathered (dirty) condition as often seen running towards the end of the steam era. Please expect a couple of weeks extra delivery time, since the weathering is done to order.
