THE remaining QR workshops behind the Workshops Railway Museum will be temporarily closed following a safety audit; however, the museum itself will remain open.
The audit found the large glass windows in the saw tooth roof were a safety hazard that needed to be made safe.
A number of buildings at the workshops will be temporarily fenced off from yesterday.
Under the workshops original design the glass panels were designed to provide light to workers inside the massive sheds.
Queensland Rail chief rail operations officer Mark Williams said the closures would see tours through the operational QR buildings postponed.
"The Rail Museum will remain open while further inspections on the Workshops' carriage, wagon and blacksmith buildings are undertaken to ensure the site is safe," he said.
"Some of these buildings are more than 100 years old, and Queensland Rail is being proactive in ensuring they remain safe.
Mr Williams said he expects staff to return to the Ipswich site as early as next week.
