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to shunt wagons from the NZR sidings up into the works. 1181 was in use until c1963 when serious boiler trouble saw it withdrawn from servie. 1181 was aquired by preservationist Len Southward who moved the loco to his factory in Seaview.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.

Built in 1921 at the Kilmarnock Scotland works of Andrew Barclay and Sons, Makers number 1749 is now the smallest Ex New Zealand Railways steam locomotive still in existence. Purchased by the Public works Department, 1749 became PWD 531.

Built in 1936, R.M.5 was one of 6 Wairarapa Railcars principally designed for use over the steep Rimutaka Incline railway between Upper Hutt and Featherston. The section between Summit and Cross Creek used the Fell Centre Rail for adhesion and braking. As this rail sat up higher than the running rails the car was designed to clear it. Originally powered with a Leyland petrol engine this was later changed to a Leyland diesel to lessen the fire risk. Mainly used between Wellington and Masterton the Wairarapa railcars did occasionally venture further afield to places like Gisborne.

R.M.34 named Tainui, has a similar history to R.M.30 except it was built with the seating arrangement it currently has as opposed to R.M.30 originally having a first class compartment. R.M.34 was the first of the Standard railcars to be repainted in the red livery. Retired in 1972, 34 was originally purchased as a source of spare parts but it was quickly decided that it would remain in operating condition.

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.

This locomotive was one of 15 of a class that were the first Diesel Electric locomotives to run in New Zealand. A diesel electric is a locomotive that uses a diesel motor to turn a generator which produces electricity to power electric motors that turn the wheels. Built in 1952 our locomotive first entered service in Wellington before moving to Auckland a few years later.

D137 was built in Christchurch at Scott Brothers in 1887 makers’ number 31, entering service with New Zealand Government Railways that year. 137 was based in Wellington all of its working life. In 1901, 137 was sold to the Gear Meat company in Petone becoming their number 2. It worked at the company's large freezing works with extensive rail sidings near the Petone foreshore.
