Addressing stakeholders, government officials, local businesses and the media at the launch, Cronin said it was important that the infrastructure grant was used wisely for the project.

"While there are great opportunities to be realised, keeping running costs manageable will be the major factor in determining the long-term sustainability of the RRT service."
Cronin said all new public transport systems would be designed to ensure that they were universally accessible and contributed to reducing carbon emission growth by 34percent by the year 2020.
Rustenburg executive mayor Mpho Khunou said the project would ensure that all stakeholders and businesses were kept informed about the opportunities of and issues facing the project.
"In delivering a transformed public transport service our primary partners will be taxi and bus operators, who at present provide services in the municipality," Khunou said.
