While the Trust's primary focus is No.9, it is also interested in the welfare of remaining Wellington and Manawatu Railway relics which have managed to survive into the modern day.

12104, Baldwin ID 10 24 1/4 D9 was one of two 2-6-2 wheel arrangement locomotives constructed for the Wellington and Manawatu Railway, and was given the road number 9.

No.9 and sister No.10 were constructed to a virtually identical design as the NZR N class of 1885, with notable differences including lengthened smokeboxes, spoked carrying wheels and no air brakes.

In 1892, No.10 set a World Speed Record for the 3 ft 6 in (1,067 mm) gauge of 64.4 mph (103.6 km/h), underlining the type's pedigree.

All other changes to the two locos during WMR service were minor, such as replacement of the original pressed steel & copper funnels in cast iron.

Despite this, in November 1926 No.9 was withdrawn from service, dismantled and tipped into the Bealey River on the Midland Line to check erosion.

The first item recovered was the locomotive frame and cylinders, which were trucked to the Canterbury Steam Preservation Society at McLeans Island, Christchurch.

As a part of the agreement with Steam Incorporated, No.9 is being restored to main line operating standard so that it can be used on the national rail network.
