The longest stretch of straight railroad track in the world, over 300 miles long without a turn, is located in which country?

This remarkable feat of engineering is found crossing the vast and arid Nullarbor Plain. The track is a segment of the Trans-Australian Railway, which connects the country's eastern states with Western Australia. This specific section, running for an astonishing 478 kilometers (297 miles) between Ooldea and Loongana, holds the record for the world's longest stretch of perfectly straight railway line.

The reason for this arrow-straight construction lies in the unique geography of the region. The Nullarbor Plain, a name derived from the Latin for "no trees," is an immense, flat expanse of limestone bedrock. With virtually no geographic obstacles like hills, valleys, or major rivers to navigate, engineers were able to lay the track in the most efficient and direct route possible.

Today, this straight section is a famous feature of the journey on the Indian Pacific passenger train, which travels from Sydney to Perth. For travelers, the long, unwavering path across the seemingly endless horizon serves as a powerful and memorable highlight of their transcontinental journey, emphasizing the sheer scale of the continent's interior.
