The station complex comprises a type 4, brick standard roadside station (1889) and platform, a
weatherboard skillion roof (1912), an out-of-shed ( 1940, and a timber and
corrugated iron goods shed. The station yard includes loading banks, weighbridge, weighbridge office and fettlers shed. The locomotive precinct includes the engine
shed (1889), engine store, turntable (1902), coal stage (timber slabs), water
column (cast iron with hose attachment), water tank (2000), original water tank site, and ash pits (4 pits, bricks and concrete). The heritage listing also includes the District Locomotive Engineer's (DLE's) Office (1950), the Barracks & Laundry ( 1940) and the Railway Institute Hall & Tennis Courts ( 1958), and the diesel depot, consisting of two small timber
sheds with corrugated iron roofs and diesel pipework. The signals and signal gantries ( 1950s), fuel unloading points including pipework and stands, signs (entrance sign, nameboards, platform signs, warning signs, heritage signs), slab (retaining and crossover), platform benches (3 timber and cast iron railway benches) and the station landscape are also heritage-listed. ;Station building (1889) The station building is a standard roadside design, symmetrically planned with
awning supported on cast iron posts and decorative
brackets. The brick building comprises seven main rooms, toilet skillion, entrance vestibule with
verandahs and platform with awning. The roof is gabled and clad with painted corrugated iron and features a central transverse
gable. The
gables display
fretwork and
finials and rendered walls have masonry detailing. The building, erected in 1888, has undergone a series of modifications but still displays its Railway Gothic architectural style with many original elements and decorative features in situ. Major modifications were undertaken during the 1920s and the 1960s, the latter owing to increased activity during construction of the Snowy Scheme. The original side pavilions have been replaced by later extensions. At one end new toilets were provided on a larger scale than previously along with additional rooms for luggage and waiting. The building is located on a brick and concrete platform. ;Signal box (1912) The signal box was erected on the platform in 1912 and is a small scalloped weatherboard building with a corrugated iron pitched gable roof. An extension was built in 1955 on the western side to house relays and batteries for track circuits and the electric staff. ;Out-of-shed ( 1940) The small building, which is presently used as a store, is known as the out-of-shed. It was relocated to the platform prior to 1949 and is thought to have been originally a waiting room at a small unattended station. The section at the rear was constructed to house batteries and electrical equipment at the time the signals were electrified. The building has a brick footing, timber
skirting, scalloped weatherboard walls, and timber sliding door. ;Goods shed and yard (1889) The goods shed is made up of four separate sections constructed over 100 years. The earliest part is the central section, dating to 1889. It has brick
pier footings, vertical
tongue and groove dado and corrugated iron walls, a corrugated iron roof, and a platform and loading stage with timber sleepers running north south. Newer sections of the shed include a 3-room and toilet addition with brick piers, weatherboard walls, and corrugated iron roof cladding, as well as Colorbond clad extension with a platform and loading stage. A suspended concrete platform
loading dock has also been added, with Colorbond cladding and a corrugated iron roof. Other important components of the goods yard are the metal weighbridge, weatherboard weighbridge office, wool and cattle loading ramps dating to 1889, consisting of concrete banks with railway line edges and gravel floors, and a corrugated iron fettlers' shed. ;Locomotive precinct (1889) The main element of the locomotive precinct is the straight type engine shed but also included is the store, turntable, coal stage, water column, water tank, ash pits and other infrastructure necessary to service and maintain rolling stock. The engine shed has 1889
English bond brickwork footings. The walls are made of vertical corrugated galvanised iron, with some panels on the east
facade made of clear corrugated perspex. The roof is clad in corrugated iron. The doors and windows date to 1997 and 1998 respectively. The engine store has concrete footings, scalloped weatherboard walls, timber doors and window frames, and a corrugated iron roof. The turntable is 60 ft in length with timber and steel platform set on a concrete pit directly connected to the engine shed and yard. ;District Locomotive Engineer's (DLE's) Office (1950) The DLE's office is a single storey face brick building, constructed in an L shape, with a corrugated galvanised iron gable roof, and timber doors, window frames, and
fascias. It was built in 1950 to provide an office for the DLE and amenities for those working in the engine shed, such as a meal room, locker room, washrooms and so on. The building has now been converted to a residence with little alteration to the floor plan. ;Barracks (1941) The building initially consisted of six bedrooms to sleep 12 men, with bathroom facilities, a kitchen and dining room. There is also a separate laundry. Some years later, between 1952-1955, an extension of four more bedrooms was attached. The interior of the building is relatively intact however four of the original bedrooms have been combined to form a meeting room. The barracks building has brick footings and walls, corrugated asbestos roof cladding, with timber post verandahs to the east and west, and a brick
chimney. ;Railway Institute and tennis courts (1958) The railway institute hall is a small, single storey building of two rooms, comprising a hall and annex, erected . The tennis court was built around the same time. The institute hall has exposed brick piers, asbestos cement sheet cladding, and a corrugated iron roof. The tennis courts consist of two gravel courts with wire netting fence, a slab
retaining wall, and timber benches. ;Landscape Photos from the 1920s show that there were no exotic plantings in the old railway yard. Since then gardening at railway stations has become a tradition with such features as rose species in forecourts, approaches lined with trees and plants in tubs on platforms. This trend is demonstrated at Cooma. The majority of the yard is covered with native grasses, which are kept slashed and quite a few areas are infested with noxious weeds. Rubbish and extraneous items have built up around the engine shed, goods shed in the ash pits and the DLE's office garden.
Condition The station was reported to generally be in good condition as at 11 November 2009. The station group including the station buildings, platforms and related structures have a high level of integrity. The Cooma Railway Station precinct retains its ability to demonstrate 100 years of rail which sets it apart from other railway sites in NSW. All necessary elements for operating the railway are in place and of the past 61 major fixed items which were previously at the railway yard, 55 are still found. == Heritage listing ==
