A new Sydney-Canberra high-speed railway
Sydney Central to Canberra Civic in 91 minutes, for less than $5 billion: A new strategy for high-speed rail in Australia which will have it built sooner, cheaper and at no net cost to the taxpayer.

Glenfield
The existing rail corridor between Campbelltown and Glenfield was rejected by the 2013 government study due to having insufficiently large radius for their unrealistically fast 400km/h design speed. However, the corridor actually has fairly good geometry, with only two curves of relatively gentle radius; the one at Leumeah has radius 1000m, while the one between Minto and Ingleburn has radius 1800m. This is sufficient for tilting trains to achieve 200km/h…
An empirical rough order of magnitude cost function for bridge structures
Bridges (over water) and viaducts (over land) can be some of the most expensive infrastructure projects in the world, especially for very long spans. The ability to obtain rough order of magnitude (ROM) costings for bridges based on very preliminary specifications is therefore an important tool for the design of any road…
