Freeway and connecting to Collingwood station, has been found to be the most viable
of the route options considered.
The alignment would feature stations at Doncaster Park-and-Ride, Thompsons Road (Bulleen) and Kew Chandler Highway, before joining the existing line at Collingwood station and on to Flinders Street.

station. DART could provide a connection between these points at a peak
frequency equating to a bus every two minutes"
