I am advised
Poor management by the former Liberal-National government led to significant time and cost over runs on the overseas built regional rail fleet. The Spanish-built Regional Rail Fleet is publicly reported to be more than three years late and more than $1 billion over budget, under the previous government. The Korean-built Mayrung Fleet was due to enter service in late 2019. It was reported under the previous government that cost overruns could exceed $1 billion.
A timeline for their delivery will be confirmed once the testing and assurance phase of the rollingstock is complete.
