Batu Arang is a town in Gombak District, Selangor, Malaysia, that is located about 50 km (31 mi) from the capital Kuala Lumpur. Coal was first discovered in the region in 1908, when British authorities found large deposits of coal reserves that could be commercially viable and fuel a railway system. The town was established when the British started mining operations. In 1915, a railway system linking Batu Arang and Kuang was built to transport coal to the rest of the country. As coal output and demand increased, rail services to and from Kuala Lumpur expanded. The demand for coal from Batu Arang skyrocketed due to the First World War, which led to a reduction of coal imports. The local coal was frequently sold to the railway companies, power stations, tin mines, dredges, and end customers.
