In Nauru, rail transport is used for moving calcium pyrophosphate from the island's interior to the cantilever jetties on the island's western coast. For this purpose, a 3.9 km (2.4 mi) long, 610 mm (2 ft) gauge was built by the Pacific Phosphate Company in 1907. The line passes through the districts of Aiwo, Buada, Denigomodu, Nibok, Uaboe and Anibare.
