Our small C class locomotive was built by Dubs and Company of Glasgow in 1875, makers number 885,  the last of the class to be built and was delivered to the then isolated Greymouth Section in December of that year. At first the locomotive was not numbered but named Pounamu a common practice at the time. In 1877 it was numbered C 132 and later in 1882 renumbered C 2. When originally built it had a 0-4-0 wheel arrangement but this was changed in 1879 to a 0-4-2 after the addition of a Bissell trailing truck.

Barclay 1181 was built in Scotland in 1909 for the Wellington Meat Export Company Ngauranga freezing works. It was used to shunt wagons from the NZR sidings up into the works. 1181 was in use until c1963 when serious boiler trouble saw it withdrawn from servie. 1181 was aquired by preservationist Len Southward who moved the loco to his factory in Seaview. In 1981 1181 was gifted to Steam Incorporated and stored at the Paekakareki depot. In1996 a group of Steam Inc's younger members nicknamed the Barclay Boys commenced work on a project to evantually return the loco to operation.

After being withdrawn in 1981 Ed101 was moved to the railway in May 1984.
 

Ww571 was built at the Hillside workshops in Dunedin in 1914 with makers number 147 and entered service on the 4th of November of that year. Initially based in Wellington, 571 was also based in places as far away as Thames and Napier before returning to Wellington in 1936, where it was mainly used on suburban passenger trains until withdrawn from service in 1953 following the introduction of the De class diesel electrics in 1952. 571 was stored along with other withdrawn engines at Hutt Workshops, its future uncertain.

Eb26 was built by NZR at the Hutt Workshops using componants supplied by the Goodman Manufacturing Company in the USA in 1929, originally as a battery electric locomotive. It was based at the workshops for many years being used on light shunting duties in the car and wagon workshop. Over time the storage batteries started to fail so a war surplus AEC generator set was mounted on the original underframe along with a new cab in 1953. The generator was hooked up to the original traction motors converting the loco into a diesel electric.

Entering service in October 1941, Ka 935 maker’s number 318 was built at Hutt Workshops in Wellington. When built 935, along with most of the rest of the Ka class were coal fired but was converted to oil firing in 1948. They were also fitted with a “streamlined” casing over the front of the smoke box, boiler and running boards. The purpose of this was to hide the ACFI feed water pump and associated piping. 935 had its casing and ACFI pump removed in 1950 and was fitted with an exhaust steam injector.
