One consideration with the Ballarat Intermodal Freight Hub is that the proposed terminal is next to the Ballarat – Ararat BG line. Assuming the MBRP is completed, it will be BG Ballarat – Melbourne via Ballan and SG Ballarat – Gheringhap.
If intermodal trains are BG they will have to find paths via the RFR.
If intermodal trains are SG then 5 km of DG track (there's room for a separate SG track) will be required between North Ballarat and the terminal (in the vicinity of the former Linton Junction, west of Wendouree). An alternative would be to SG North Ballarat – Ararat.
The proposal thus far has the State government only kicking in for a set of points and some signalling. If BG is adopted, it should be a requirement of the developer that the sidings be gauge-convertible.
