Description

Designer/Maker: American Locomotive Company (ALCo), Schenectady, New York
Builder/Maker: A.E. Goodwin Pty Ltd
Physical description: EXTERNAL
This is a Mk 1 Diesel/Electric Goodwin Alco 1959, 900 hp double-cab (Co-Co) branchline locomotive, Model DL531. It is 14.76m long, and weighs 75t.

MECHANICAL
This locomotive is fitted with an Alco 6-251B engine, a GE GT584 generator, and GE 761 traction motors. It produces 780 kW / 1050 HP of power and has a tractive effort of 225 / 151 kN.
Physical condition and/or
Archaeological potential:
Operational Status: Non-Operational
General Condition: Poor Condition
External Condition: Poor Condition
Internal Condition: Poor Condition

EXTERNAL CONDITION
The body is in a poor condition due to severe corrosion as a result of being exposed to the elements. Handrails have been removed, draw gear is missing, the No.2 pilot light is removed, and head lights at A & B ends are missing. The fuel tank and air reservoir have been removed. Cab windows are broken, and there is graffiti on the body. Electric traction motors, air brake cylinders, and axle box covers have been removed. Wheel profiles are in poor condition. Many fittings have been removed, including the exhaust, radiator cover, engine pipework, injector covers and air intake filters. Note that a Hasler generator has been removed from an axlebox allowing contamination of the bearing. This needs to be covered as a matter of urgency and certainly prior to movement.

INTERNAL CONDITION
Many parts are missing due to being scavenged for spare parts for other 48 class locomotives. The wash basin, whistle valve and hand brake have been removed. The electrical cabinet has been stripped and seats are missing.

HAZARDOUS MATERIALS
Possible asbestos in electrical gear, lead based paints.

History

Historical notes: The 48-class locomotive is the most numerous class of diesel locomotive used in NSW. The class worked on every line due to its light axle load. Developed by ALCO and built under licence by A E Goodwin Pty Ltd at their St Marys workshops, the first locomotive was completed in 1959. Built to the American Locomotive Company DL531 design, the 48-class were to become the backbone of the NSW Railways, eliminating steam haulage from branch lines but also being used for mainline duties. Such was the popularity of the DL531 design that a total of 165 48-class units were eventually placed in service with the NSWGR as well as 44 being built for the South Australian Railways and another 3 for the Broken Hill based Silverton Tramway Company.

During their service life the 48-class proved to be extremely reliable units as well providing the flexibility to haul all types of trains over all lines in the NSW rail network. Despite having worn many different liveries and undergone various modifications their basic configuration remains the same as when first delivered. Several have been preserved in running condition and many are still being used in traffic.
