Australia’s Heritage Recognition Guidelines and had been awarded Project Planning an Engineering Heritage National Landmark. The project was a major undertaking which required a planning Origin of the Project commitment of considerable magnitude and complexity. A The original 618 km 3ft 6in narrow special planning section was gauge (NG) railway joining Fremantle established by the Western Australian and Kalgoorlie was completed in Government Railways (WAGR) and a 1897. By an unfortunate accident senior departmental officer, the Co− of history the five mainland states ordinator of Standard Gauge Railway, had built their railways on three was appointed to be responsible different gauges, Queensland and for all aspects of planning. Because Western Australia had built narrow of the size of the project WAGR gauge railways, New South Wales appointed engineering consultants standard gauge ( 4ft 8½ in , SG), Maunsell and Partners to assist with and Victoria broad gauge ( 5ft 3in, the planning and to design and BG), while South Australia had both supervise the construction of a major broad and narrow gauge.

Avon Valley Midland to Northam The first and most difficult section of the project was a new route through the Darling Range. Forty kilometres of this alignment was confined within the narrow, steep−sided gorge of the Avon River valley. Tenders were called for contact C1 which provided for two bridges across the river near Bells Rapids. Thiess/Perron submitted an alternative (and more Blasting at Monument Hill cutting C1A Contract 1963 competitive) tender deleting the two bridges and replacing them with two large cuttings. Tenders were recalled with the additional earthworks option and subsequently C1A contract was awarded to Thiess/Perron for the work between Millendon and Smiths Hill. Contact C2, awarded to Leighton Contractors, incorporated an exceptionally deep cutting at the Windmill Hill site, between Toodyay and Northam, where the cutting was 100 ft (30.5m) deep at the formation centre line. Approximately 70% of the excavation in the Avon Valley route was in rock which was Excavating at Monument Hill cutting C1A Contract heavily jointed and faulted and was 1963 decomposed to a considerable extent, necessitating variations in batter slopes and benching in the deeper cuts. Construction work began in November 1962 when the then Premier of WA, the Hon ( later Sir) David Brand, with the Minister for Railways, the Hon ( later Sir) Charles Court looking on, pushed a plunger to initiate a blast to commence excavation of the main cutting at Monument Hill.

Toodyay and Northam Staging of the works through Northam was complicated because no interruption to traffic through this junction could be permitted. A major new marshalling yard, the Avon Yard, serving both gauges 3.

Some substantial service involving two crossings of the Avon diversions were necessary over this at Northam, another Avon crossing section, principally to the Great by the Calingiri & Miling NG line Eastern Highway, the Goldfields at Toodyay, and a rail over road Water Supply and the East−West crossing at Northam. Telephone Trunk route. A new marshalling yard for both gauges was provided on the western side of the town of Merredin and the three existing NG branch lines, from Nungarin ( to the north) and Bruce Rock and Narembeen (to the south), were connected into the yard. On 11 November 1966, the first SG train ran from Merredin through to the Leighton Yard at Fremantle.

Investigation of installations required to service all major catchments was made freight and passenger rolling stock. by helicopter, and of the smaller ones by wheeled vehicles. In areas subject to sheet flow, bunds and cut−off drains were provided to protect the toes of embankments. Culverts were sized to allow for the high rainfall intensities associated with remnant cyclones from the north−west passing through this area. Much of the route east of Koolyanobbing passes through salmon gum and morel woodland which has fine silty ‘bull−dust’ soil. Embankments of this material required special compaction and protection with layers of gravel. Forrestfield Locomotive Depot 5.
