Statement of significance:

Steam Locomotive 5595 has heritage significance as part of a class that was introduced to meet the increasing demand for goods traffic on the NSWGR. The construction of 5595 by Clyde Engineering in 1912, reflects the trend towards the acceptance of local manufacture of railway locomotives and the development of local railway technology. The locomotive is an interesting synthesis of American and British railway design practice, particularly in its use of the unusual American "Southern" valve gear, and successfully remained in traffic until withdrawal in the mid-1960s. Locomotive 5595 is rare as the only survivor of 120 examples of the D-55 Class.

Description

Designer/Maker: William Thow and EE Lucy
Builder/Maker: Clyde Engineering Ltd, Granville, NSW
Physical description: MECHANICAL
Locomotive 5595 is a two-cylinder, simple, non-condensing, superheated, coal-fired 2-8-0 ‘Consolidation’ steam engine. Locomotive 5595 is a member of the K class, and is fitted with a Belpaire firebox and Southern patent outside valve gear driving the outside cylinders, with fluted coupling and connecting rods. It is of typical NSWGR profile with a ‘trademark’ William Thow porthole cab window, and has a typically British appearance in the high shapely chimney and dome. Although the running plate is higher, it is relieved in way of the valve gear hangers, slightly valanced and radiused down to the buffer beam forward of the cylinders. It has small diameter wheels for goods working and is fitted with a 5,000 gallon ‘Commonwealth’ bogie tender of riveted construction. The two inside sets of driving wheels are fitted with flange-less tyres. It is provided with electric power driven from a boiler-mounted turbo-generator, driving a headlight and marker lamps. The locomotive and tender are fitted with automatic couplings.

The engine and tender are painted overall black, with red running plat edges, and red rims on the cab porthole windows and with the road numbers in white on the front buffer beam, with brass numerals on the cab sides.
Physical condition and/or
Archaeological potential:
Operational Status: Non-Operational
General Condition: Good Condition
External Condition: Good Condition
Internal Condition: Moderate Condition

EXTERNAL CONDITION
The frames, though corroded are in fair condition, with encrusted dirt and grease. The transverse structural members are displaying hard-scab pitting corrosion and scale build-up in crevices with no protective paint system evident. Driving wheels are in good condition with a significant amount of tyre wear remaining. The pony truck bogie and frame is heavily fouled with dirt and grease. The brake system appears intact with many components appear with pitting corrosion. The air receiver is generally covered in surface corrosion and no paint system remains.

The external condition of the boiler shell is unknown, though surface corrosion is expected. The steel cladding is in part corroded at the lower levels, though the paint system is good. Lagging is present under the cladding and appears to be asbestos. The firebox wash out plugs and mudhole door are missing. (A threaded plug was found under the footplate) Injector steam pipe (RHS) missing. Small diameter cylinder lubricating oil delivery piping missing L&RHS.

Corrosion and scale build-up is evident in way of the smokebox, and also the firebox behind the air receiver.

Cylinders are in moderate condition with asbestos lagging present. There is a build-up of corrosion and scale in way of the frames. The motion and rods are in good condition though there is evidence of hard-scab pitting corrosion especially in the fluted area of the RHS connecting rod under the paint system.

INTERNAL CONDITION
The internal condition of the boiler is unknown. The brick arch in the firebox has collapsed, and the grate has generally been removed. Cab ceiling timbers are in moderate condition. Some boiler mountings are missing. Two gauge glasses are missing, one pressure gauge glass is broken, and other instruments and controls have been partially dismantled or are missing capillary lines. The multi-position light switch is incomplete and hoses are perished.

HAZARDOUS MATERIALS
Asbestos is present under cladding on boiler barrel, backhead, cylinders and air compressor. Asbestos may be also present in jointing material on all pipe flanges. Assume lead is present in all extant paint systems.
Date condition updated:09 Nov 09
Modifications and dates: 1920s - built by Clyde Engineering as part of an initial order of 120 locomotives of the K class and completed as builder’s number 334
1924 - entered service
1930s - Rear sandboxes were fitted under the seats in the cab with access from a port in the cab side. Originally fitted with flanges on all driving wheels, these were progressively removed from the two inside sets of drivers. The original tapered boiler was replaced in the late 1930s with a standard superheated boiler (used for all three standard goods classes from 1935). Originally fitted with an outside bearing pony truck, this was later (1930s) altered to an inside bearing arrangement.
July 1966 - withdrawn and condemned
1975 - transferred to the New South Wales Rail Transport Museum
Current use: NSW Government Railways Collection
Former use: locomotive

History

Historical notes: Locomotive 5595 was built by Clyde Engineering as part of an initial order of 120 locomotives of the K class, placed on 13 March 1916. Completed as builder’s number 334, it entered service in 1924. The class was introduced to meet the increasing demand for goods traffic on the NSWGR. Constrained by existing axle load restrictions on many lines (no increase in axle loadings could be made) the class remained a development of the earlier T and TF classes. On entry to service the class saw service on all mainlines. The class was the third of the three "Standard Goods" classes. They were allocated in large numbers at Enfield with allocations in major regional depots such as Goulburn, Cowra, Harden and Junee. Mindful of the high cost of maintenance, the Chief Mechanical Engineer of the day, E.E.Lucy, modified Thow’s original specifications further by adopting the ‘Southern’ valve gear and placing the outside bearings on the leading pony truck. These modifications were not totally successful, the valve gear being sensitive to vertical track irregularities, affecting valve events. Displaced from the heaviest mainline goods traffic by the D57 class and the later D58 class engines, the standard goods continued on in service past the more modern larger classes until the end of steam traction on the NSWGR in 1972. The final years were spent in Sydney and Cowra, mainly on trip trains and suburban shunting, but also some enthusiast trains in the 1960s. Locomotive 5595 was withdrawn and condemned in July 1966. It was transferred to the New South Wales Rail Transport Museum and arrived at Thirlmere in 1975, where it is on display.
