The 73 class are a diesel-hydraulic locomotive built by Walkers Limited, Maryborough for the New South Wales Government Railways between 1970 and 1973.
History
The New South Wales Government Railways placed an order in October 1969 with Walkers Limited, Maryborough for 20 Bo-Bo shunting locomotives.[1] These were the only New South Wales locomotives to be built in Queensland.[2]
Delivery
The first unit was delivered in October 1970. When the whole of the first order had arrived, all steam shunting on the North Coast line and the Sydney Metropolitan area, as well as at Goulburn had been replaced. In July 1971 a further 30 units were ordered. The last of these arrived in March 1973 and this brought to an end all remaining steam shunting operations in New South Wales.[1]
In traffic
The New South Wales Government Railways purchased the class mainly for shunting and their prohibition from mainline use was 'officially' due to the lack of vigilance controls. However, despite its absence, the class was still seen on many suburban trip workings and when mainline operation was a necessity, there seemed to be no hesitation to use them.
One advantage a diesel-hydraulic locomotive has over a diesel-electric variety is its ability to negotiate up to 300mm of water over the tracks. Big floods in March 1976 gave 7323 an opportunity to show off its swimming ability when water covered the line near Bourke and this locomotive was used on a couple of freight trains and a ballast train from Nyngan to Bourke and return. At least two other occasions when their water resistance was put to use was Menindee in 1976 and Hexham in 1977.
Multiple unit operation was common, although the flood event at Hexham is the only known occurrence of triple-heading. A number of units were fitted with exhaust gas scrubbers for use on Eastern Suburbs Railway construction in the 1970s.[3]
Depot allocation
As an example of the spread of the members of the class throughout the system, the fleet was allocated as follows as at 30 August 1977:
| Depot | Allocation |
|---|---|
| Eveleigh | 7301–7314, 7317, 7321, 7339–7345 |
| Goulburn | 7315, 7316 |
| Cootamundra | 7319 |
| Junee | 7320 (actually working at Albury) |
| Lithgow | 7326 |
| Orange | 7322 |
| Dubbo | 7323, 7324 |
| Parkes | 7325 |
| Broadmeadow | 7327–7338 |
| South Grafton | 7318 |
| Werris Creek | 7346 (actually working at West Tamworth), 7347 |
| Yeerongpilly | 7348–7350 |
Withdrawal
With a reduction in locomotive hauled passenger trains and the closure of a number of yards, withdrawals began in February 1987.[4] By October 1991 only three remained in service with FreightCorp.[5] One was repainted into CountryLink livery for use as a depot shunter at the XPT Service Centre.
Disposals commenced in 1990 with three sold to the Canberra Railway Museum.[6] Four were sold to the Manildra Group in 1991.[7] Many were sold to Queensland sugar cane companies for conversion to 610 mm (2 ft) gauge.[8] A number have also been preserved.[9][10][11]
7301 & 7344 were placed on RailCorp's Heritage & Conservation Register.[12][13] 7301 was subsequently scrapped in January 2014.[14][15]
