33-647: The name of the brook is also the name of a number of features and organisations, including the Wooroloo Brook Landcare Group, the Wooroloo Brook Land Conservation District Committee. The brook alignment had been considered a possible route for the connection of the railway routes occurring at the time of the development of the Trans-Australian Railway . The locality of Wooroloo is in the upper reaches of

66-503: A desert, the original engineer, Henry Deane envisaged diesel locomotives for the line and made inquiries with potential manufacturers, although the technology was not well developed at the time. Unfortunately, a scandal involving the supply of sleepers led to Deane's resignation before the proposal had advanced. Initially trains were hauled by G class locomotives and from 1938 by C class locomotives, both steam. From 1951, diesel-electric locomotives hauled passenger services, using

99-534: A former sheep station at Yalata , where Yalata Mission was established by the Evangelical Lutheran Church of Australia . This was an environment quite alien to them, being desert people. The town was dependent on the Tea and Sugar Train for the delivery of supplies until 1996 when the train was withdrawn. The longest dead straight section of railway line in the world starts west of Ooldea before Watson at

132-545: A route from Port Augusta (the existing railhead at the head of Spencer Gulf in South Australia's wheatfields) via Tarcoola to the gold mining centre of Kalgoorlie in Western Australia, a distance of 1,063 miles (1,711 km). The line was to be built to the standard gauge of 4 ft  8 + 1 ⁄ 2  in ( 1,435 mm ), even though the state railway systems at both ends were narrow gauge at

165-403: A very fine pencil line across the desert". At no point along the route does the line cross a permanent fresh watercourse. Bores and reservoirs were established at intervals, but the water was often brackish and unsuitable for steam locomotive use, let alone human consumption, so water supplies had to be carried on the train. In the days of steam locomotion, about half the total load was water for

198-479: Is by train orders , using verbal communication. In the time of the operation of the railway, 'washaways' and 'flooding' in most cases rendered the railway inoperable at a range of locations. Washaways usually removed ballast, leaving rails suspended above the flooding areas. In most cases the underlying ballast was removed, and required replacing. Significant events on the line were in 1921, 1930 1937 and 2022. The 1930 flooding had two trains held up on sections of

231-545: The South Australian Railways extended its 1,600 mm ( 5 ft 3 in ) broad-gauge line 47 km (29 mi) north to Port Pirie from Redhill . These two projects made redundant the indirect 290 kilometres (180 miles), 1,067 mm ( 3 ft 6 in ) narrow-gauge connection from Terowie via Peterborough and Quorn, resulting in a much shorter and more comfortable journey to Adelaide . These two projects eliminated one break of gauge in

264-508: The Trans-Australian Railway . Ooldea is 143 km (89 mi) from the bitumen Eyre Highway . The site had a permanent waterhole, Ooldea Soak , also known as "Yooldil Kapi" in the language of the Aṉangu. The presence of the water caused it to became the site of a camp for railway construction workers in the early 20th century, and the Ooldea Mission from 1933 to 1952. The soak dried up and

297-509: The privatisation of Australian National, the Indian Pacific was sold to a company, Great Southern Rail (as of 2020 trading as "Journey Beyond"). As of 2020 , the Indian Pacific is a weekly, all-through, experiential tourism service. From the start of construction until 1996, the Tea and Sugar supply train carried vital provisions to the work sites and localities, all of them isolated, along

330-400: The turnouts as required. Crossing loops have self-restoring points, so that points are reset to the straight route when a train departs from a crossing loop. The loops are fitted with radio controls so that train crew can set the points as they approach. Locomotive cabs are fitted with an activated points system (ICAPS) to set the required route without having to stop the train. Safeworking

363-505: The 797 km post and continues to a point between Loongana and Nurina , a distance of 478 km (297 mi). The historic Ooldea Soak and Former United Aborigines Mission Site and Daisy Bates' Campsite are both listed on the South Australian Heritage Register . Yooldil Kapi was handed back to the Aṉangu people in 1991 and is as of 2023 closed to the public. In 2023, Bangarra Dance Theatre performed

396-674: The area, who were Pila Nguru (Spinifex people, of the Great Victoria Desert ) were moved to the Ooldea Mission, which closed in 1952 due to internal divisions in the church. The people did not want to move from there, as they were used to ranging the desert, and had used the Ooldea Soak as a water source for many generations. The people were forcibly moved to a reserve established by the South Australian Government on

429-738: The catchment. The catchment runs through the locality of Gidgegannup and the confluence with the Avon River is where the Swan River commences. Trans-Australian Railway [REDACTED] The Trans-Australian Railway , opened in 1917, runs from Port Augusta in South Australia to Kalgoorlie in Western Australia , crossing the Nullarbor Plain in the process. As the only rail freight corridor between Western Australia and

462-576: The eastern states , the line is economically and strategically important. The railway includes the world's longest section of completely straight track. The inaugural passenger train service was known as the Great Western Express ; later, it became the Trans-Australian . As of 2020 , two passenger services use the line, both of them experiential tourism services: the Indian Pacific for

495-472: The engine. In later years, condenser plants were built at several major stations. Reflecting the line's ownership by the Commonwealth Government , eight of the localities were named (or renamed) after Australian Prime Ministers . Other prominent people's names were also allocated, as shown on the adjacent map. Because of the inevitable problems of finding suitable water for steam locomotives in

528-486: The entire length of the railway, and The Ghan between Port Augusta and Tarcoola , where it leaves the line to proceed north to Darwin . In 1901, the six Australian colonies federated to form the Commonwealth of Australia . At that time, Perth , the capital of Western Australia , was isolated from the remaining Australian states by thousands of miles of desert terrain and the only practicable method of transport

561-432: The final link of the railway was completed at Ooldea, linking the western section from Kalgoorlie to the eastern section to Port Augusta . It was around this time that a severe drought led many desert people to migrate closer to the waterhole, increasing pressure on the limited water resources now largely reserved for use by trains. A centenary celebration was held at the siding in 2017. The settler town that sprung up

594-688: The gap in standard gauge connections between the mainland state capitals was finally closed with a connection between Port Pirie and Adelaide, thence Melbourne , and by completion of the northern component of the Adelaide–Darwin railway line , which diverges from the Trans–Australian Railway at Tarcoola. In 2008, the engineering heritage of the railway was recognised by the Engineering Heritage Recognition Program of Engineers Australia when markers were installed on

627-458: The high mineral salt content of bore water available along the route was playing havoc with steam locomotive boilers : repairs to boilers at one time accounted for an extraordinary 87 per cent of all locomotive maintenance. The problem was only arrested with the introduction of barium carbonate water treatment plants at watering points. In 1937, the eastern end was extended 90 kilometres (56 miles) south to Port Pirie . Soon afterwards,

660-408: The journey across Australia, but they turned Port Pirie Junction yard into a complex three-gauge facility. Railway engineers, however, were able to construct the new yards with no more than minimal dual-gauge track and the complex signalling that would have been incurred. The long-anticipated conversion of the entire line between Sydney and Perth to standard gauge occurred in 1970. In 2004,

693-404: The line. 32°28′02″S 137°46′00″E  /  32.46709079°S 137.76673101°E  / -32.46709079; 137.76673101 Ooldea Ooldea , known as Yuldea and various other names by Western Desert peoples ( Aṉangu ), is a tiny settlement in South Australia . It is on the eastern edge of the Nullarbor Plain , 863 km (536 mi) west of Port Augusta on

726-492: The new GM class locomotives. The railway originally had 400 m (1,300 ft)-long crossing loops (passing sidings) every 100 km (62 mi) or so. As traffic increased the number of crossing loops increased. To handle longer trains, crossing loops were lengthened so that in 2008 they were all at least 1,800 m (5,900 ft) long and spaced about 30 km (19 mi) to 60 km (37 mi) apart. Most crossing loops are unattended and train crew operate

759-520: The platform at the Port Augusta station in South Australia and the ticket office at Kalgoorlie station in Western Australia. On 17 October 2017, centenary celebrations were held at Ooldea. When the line was inaugurated, the passenger service was named as the Great Western Express . Later, the train became known as the Trans-Australian or, colloquially, "The Trans". After the Sydney–Perth route

792-425: The route: a butcher and banking and postal services were among the facilities provided. The length of the line, as constructed, was 1051.73 mi (1692.60 km), slightly less than the original survey. Although there are several hundred curves and gradients on the line, the route includes the longest length of straight track in the world – 478.193 kilometres (297.135 miles). A Commonwealth Railways map marked

825-503: The site was closed to the public in 1991. The soak , known as Yooldil Kapi to the Aboriginal peoples of the area, and Ooldea Soak to the European settlers, made it an important camp during construction of the Trans-Australian Railway . The soak is a permanent clay pan waterhole surrounded by sand dunes, first discovered by Europeans when Ernest Giles used it in 1875. On 17 October 1917,

858-884: The time. Its cost was estimated at £4,045,000. Legislation authorising the construction was passed in December 1911 by the Fisher Commonwealth Government . Work commenced in September 1912 in Port Augusta . Work proceeded eastwards from Kalgoorlie and westwards from Port Augusta through the years of the First World War . Tracklaying proceeded briskly when materials were available. At its peak, up to 2 + 1 ⁄ 2 miles (4.0 km) of track were laid each day, and 442 miles (711 km) were completed in one calendar year – both Australian tracklaying records. By 1915,

891-538: The two ends of the line were just over 600 miles (966 km) apart with materials being delivered daily. Construction progressed steadily as the line was extended through mainly dry and desolate regions until the two halves of the line met at Ooldea on 17 October 1917. Under the aegis of the federal department of transport, the Commonwealth Railways was established in 1917 to operate the line. Once passenger trains started to run, maintenance staff found that

924-428: The western end as 793 miles (1,276 km) from Port Augusta, between Loongana and Nurina, and states: "The 'Long Straight' extends from this point for a distance of 297 miles and terminates at the 496 miles [sic] between Ooldea and Watson." According to South Australian astronaut Andy Thomas , the line is identifiable from space because of its unnatural straightness: "It's a very fine line, it's like someone has drawn

957-490: Was absorbed into an enlarged federal government corporation, Australian National Railways Commission , branded as Australian National Railways and later as "Australian National", which continued to operate the Trans Australian. In 1993, Australian National took over operation of the entire coast-to-coast service following agreement with the governments of Western Australia and New South Wales . In 1997, following

990-440: Was by sea. The voyage across the notoriously rough Great Australian Bight was time-consuming, inconvenient and often uncomfortable. One of the inducements held out to Western Australians to join the new federation was the promise of a federally funded railway line linking Western Australia with the rest of the continent. In 1907, legislation was passed, allowing for the route to be surveyed. The survey, completed in 1909, endorsed

1023-542: Was converted to standard gauge in 1970, the railway was no longer flanked at both ends by narrow-gauge lines and an all-through service, called the Indian Pacific , was started. Although passengers no longer had to move to different carriages at change-of-gauge localities, Commonwealth Railways remained responsible for the service where it operated between Port Pirie and Kalgoorlie , with its crews and locomotives taking over at those stations. In 1975, Commonwealth Railways

1056-629: Was home for many years to Daisy Bates , both concerned with understanding and protecting Aboriginal culture. A cairn commemorating Bates was designed by F. Millward Grey and erected in 1953. In the 1950s, areas around Maralinga and Emu were used for nuclear testing by the British Government . Around this time the Australian Government resumed much Anangu land to be used for the Woomera Rocket testing Range . Aboriginal people in

1089-480: Was named Ooldea, but was also referred to as Yuldea, Youldul, Yuldeh, or Yultulyngya. It was the site of a mission known as Ooldea Mission, established by the United Aborigines Mission (UAM) in 1933. It later included a children's dormitory housing around 60 children. In 1938 an Aboriginal reserve was created covering the land around the mission. The mission was visited twice by Norman Tindale and
