THE Rail, Tram and Bus Union has vowed to appeal a decision by Fair Work Australia forcing them to work on the type of train that made national headlines after smashing into a Brisbane station last week.
The crash, which caused minor injuries, is under investigation by QR, the Australian Transport Safety Bureau and Queensland's Department of Transport.
The union's ban on the 160 and 260 class of train - the type that crashed into the Cleveland station last week - was found to be unreasonable after Queensland Rail took the dispute to court on Friday night.
On Monday afternoon, RTBU Queensland state secretary Owen Doogan said there were strong grounds for appeal and a good chance of success.
Mr Doogan said the safety of RTBU members and passengers was the union's only motivation.
"Many drivers have indicated their shock at the decisions of Fair Work and Queensland Rail to force them to undertake work which could cause an imminent risk to their safety, and thus the safety of the travelling public," he said.
QR has staunchly defended the safety of its trains, saying no issues have been reported or found since it began using this class of rolling stock.
