Both tracks on Australia's Blackwater System have resumed operations following a train derailment on Friday, a spokeswoman for operator Aurizon said in an email on Wednesday.
"The repairs were completed at approximately 6:30 pm [AEST, 0830 GMT] last night and both tracks are now operational," she said.
The Blackwater System connects coal mines in the Bowen Basin to the port of Gladstone in Queensland.
The derailment of a loaded coal train near Westwood, west of Rockhampton, occurred around 9 pm AEST on Friday. Following the derailment, Aurizon was operating a single track on that part of the system, which resulted in some delays and cancellations, it said.
A spokeswoman for the Gladstone Ports Corporation said on Tuesday that it had caused "several train cancellations at the RG Tanna Coal Terminal."
Aurizon declined to comment on whether the line was back to full capacity or how many trains were canceled.
Major Aurizon customers in the Blackwater System include BHP Mitsubishi Alliance, Jelinbah Resources, Wesfarmers and Glencore.
Gladstone shipped out 6.05 million mt of coal last month, up 6% from July last year but down 3% from June, GPC said earlier in the month.
Approximately 70% of cargoes handled by the port comprises metallurgical coal and the rest thermal.
Japan receives the lion's share of coal exported from Gladstone, while China, India and South Korea are also major customers.
