The State Government has advised that passenger services along the North Terrace tram extension will not commence on Sunday 29 July.
Signalling issues were identified during driver training which are currently being investigated, meaning driver training has been unable to continue.
“This is a very frustrating development in this problem-plagued project,” said Minister for Transport, Infrastructure and Local Government Stephan Knoll.
“This project has been riddled with problems from the outset and the State Government would like to apologise to South Australians for the inconvenience, uncertainty and delays this project has caused over the last 12 months.
“Testing is underway to identify the exact fault which will need to be rectified before passenger services are able to commence safely.
“The State Government’s absolute priority is passenger safety and it is our responsibility to ensure that South Australians are as safe as possible when using this service.
“Experts from Hanning and Kahl, which provided the tram signalling system, are being consulted and are flying to Adelaide from Germany to help rectify this issue as soon as possible.
“Every effort is being made to fix this problem and get passenger services up and running as soon as possible.
“These latest issues will also be captured by the State Government’s review of this project once complete.”
