It allows the construction and maintenance of a railway about 4 miles long connecting Muja (on the existing Collie-Narrogin Railway) to the Centaur Coal Mine near Collie in Western Australia's South West. The Schedule provides precise technical directions for the route using old surveying measurements (chains and miles). The law has been updated once in 2010 only to fix formatting, not to change the railway route or purpose."},"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
