It connects Port Augusta in South Australia to Kalgoorlie in Western Australia. This line crosses the huge Nullarbor Plain. It is the only rail corridor for freight between Western Australia and the eastern states. Because of this, the line is very important for the economy. The track is 1,693 miles long. It even includes the longest section of completely straight track in the world.

An astronaut named Andy Thomas said it looks like a pencil line from space.

Building the railway was a massive job that took many years. In 1901, the Australian colonies joined to form a single nation. At that time, Perth was isolated from other states by thousands of kilometres of desert. People had to travel by sea across the rough Great Australian Bight. To fix this, leaders promised a railway to link the continent. Work started in Port Augusta in September 1912.

Workers built from both ends at once. The two sides finally met at Ooldea on 17 October 1917. At its peak, crews laid 11 miles of track in a single day.

Early engineers faced many hard jobs while running the trains. Steam locomotives needed a lot of water to work. However, the water in the desert bores had a high salt content. This salt caused major damage to the engine boilers. In fact, boiler repairs made up 87 per cent of all maintenance. To fix this, workers used barium carbonate water treatment plants. Later, the railway switched to diesel-electric locomotives in 1951.

This change helped the engines run much better.

As time passed, the railway changed to make travel easier. Until 1970, the tracks at each end used a different width. This was called a narrow gauge. In 1970, a project made the whole line a standard gauge. This meant trains could travel from Sydney to Perth without stopping.

In 2004, the connection between all mainland state capitals was finally finished. The railway is so special that Engineers Australia recognized its history in 2008. They placed markers at the stations in Port Augusta and Kalgoorlie.

Today, people use the railway for more than just moving goods. Two special passenger services offer amazing trips through the desert. One is called the Indian Pacific, which travels the entire length.

The other is The Ghan, which travels between Port Augusta and Tarcoola. These are experiential tourism services. This means they are designed to let people enjoy the scenery. You can see the vast desert and the straight tracks from your window. It is a unique way to see the heart of Australia.
