Once the most ubiquitous locomotive in New South Wales (and Australia), the locomotives were built by A. E. Goodwin, based on Alco frames and prime movers, using General Electric (later AEI) electrical equipment. With 165 examples of the type built over 11 years, the 48 Class was a common sight on lines all over New South Wales. The South Australian Railways 830 class were of a very similar design.

Buffing Plate
To suit coupling to passenger cars fitted with concertina gangways, the 48 class were fitted with buffing plates, which were rather like buffers linked together. Eventually when locomotive hauled passenger cars disappeared, the buffing plates were removed.
History
The 48 Class have an Alco 6-251B prime mover delivering 1,060 horsepower, and have a maximum speed of 120 km/h. They ride on standard gauge Co-Co bogies, are 14.76 metres long, and weigh 75 t. Delivered in four batches (broken down as follows), there are still 69 48 Class locomotives in operation, primarily with Pacific National. Silverton Tramway and Railcorp also operate a few such locomotives. Junee Railway Workshop (formerly Austrac) own 4814, 4816, 4820 and 4836. JRW are rebuilding 4820 with a new powerplant, dynamic brakes and full-width cab. GrainCorp have twenty-four locomotives which are gradually being refurbished for grain operation. Most others have been scrapped, stored, or purchased by heritage groups.
The four batches are as follows:
- Mark I: 4801 – 4845
- Mark II: 4846 – 4885
- Mark III: 4886 – 4899, 48100 – 48125
- Mark IV: 48126 – 48165.
Currently there are seven preserved locomotives, five of them in operational status:
- 4801: State Rail Authority Heritage Unit, Eveleigh - since moved
- 4803: New South Wales Rail Transport Museum, Thirlmere, NSW. Operational.
- 4805: State Rail Authority Heritage Unit, Eveleigh. Inoperable. - Visible between Newtown and Redfern in the sidings - since moved.
- 4807: Australian Railway Historical Society - Canberra Railway Museum. Operational.
- 4821: Goulburn Rail Heritage Centre Operational.
- 4822: Dorrigo Steam Railway and Museum.
- 4833: Privately owned by Goodwin ALCo Ltd. Operational.
Various members of the 48 Class have had a total of Seven liveries over their more than 40 years of service. On delivery they wore the standard NSWGR Tuscan livery (to which some preserved locomotives have been restored), but since then have worn the State Rail Authority’s 'Candy' scheme, along with FreightCorp's plain blue, in which most locomotives remain. Some have gained Pacific National markings.
In July 2010 locomotive units 4818, 4855, 4860, 4861, 4865, 4866, 4869, 4873, 4874, 4876, 4879, 4880, 4882, 4883, 4885 were lifted off their bogies and were scrapped at Werris Creek. for the full list of the 48 class please click here
PL class
Seven Mark II locomotives were rebuilt between 1999 and 2001 as the PL class. These locomotives were 4848 (became PL1), 4856 (PL7), 4867 (PL6), 4868 (PL4), 4870 (PL3), and 4871 which became PL2. Changes included the short end cab nose being lowered, the cab altered, and the installation of air-conditioning. PL1 and PL2 were transferred to South Australia after the forming of Pacific National for use at Keswick Terminal shunting for Great Southern Rail which was prior a National Rail contract. PL2 was transferred back to NSW with PL1 remaining in South Australia with its place taken by a 81 class loco when work is needed on the loco. In NSW the class see use on the former South Maitland Railway hauling coal along with 48 class locos. Their future is uncertain as the S.M.R will be brought up to mainline standard.
DA7
4813 and 4826 were sold to Australian National with 4813 rebuilt as DA7 for the Port Lincoln Division with 4826 scrapped some years latter at Pt Augusta. DA7 was the first narrow gauge loco in the GW orange due to being rebuilt at the time of the AN sale. With the new number system that was introduced it latter became 905 and to this day is still based at Port Lincoln.
CAR1
4812 was rebuilt and repainted by Cargills for Shunter at their Kooragang Island plant as CAR1. CAR1 was sold to J.R.W some time latter it believed it will be rebuilt at some point.
Models
The 48 class and its sisters the ST and 830 class have been produced in HO scale (1:87) by Trax/Powerline. Currently Powerline are working on a retooled 48 class, while Trainorama are concurrently in the process of producing a 48 and 830 class. In the early 1970s, Berg's hobbies produced a number of brass locos which featured a 48 class model. Gopher Models have produced an N scale (1:160) model of the 48 class and the SAR-AN 830 class.
Colour Schemes
All 48 class were delivered in the Indian Red Scheme and have gone to be one of the most repainted class of locomotive in Australia.
