Exclusion zone put in place as 26-carriage train carrying sulphuric acid derails
A 26-carriage freight train carrying sulpuric acid derailed in Australia.
A 2km exclusion zone has been put in place after the accident which occurred shortly after 10am Sunday (local time).
Some 200,000 litres (44,000 gallons) of sulphuric acid were being transported at the time of the incident.
Three train staff are in hospital with minor injuries after the train derailed 20km (12.4 miles) east of Julia Creek in north-west Queensland.
The site was quickly declared an emergency as the extent of any acid leakage remains unclear.
Access to the site has been hampered due to earlier flooding in the area.
The cause of the accident is not yet known.
Sulphuric acid is a highly corrosive substance that can cause severe burns on contact with skin.
