Stations

AECOM13 manages to spend $7.1 billion on new and unnecessarily expensive stations (indeed, compare this cost to the actual track, at only $6.6 billion). This post demonstrates that this cost is excessive by comparison to contemporary examples, and proposes a more realistic and affordable estimate. The Hot Rails strategy, in…

An empirical rough order of magnitude cost function for bridge structures

http://www.highestbridges.com/wiki/images/5/50/1YanjinheArchBridge.jpg

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…

Track costs

Although the track cost estimates in AECOM13 are reasonable, they are based on just one real-world example from Germany, and additionally are specifically for very high speed track (400km/h). The Hot Rails strategy only requires 200 to 250km/h quality track, for which the required tolerances and material strength is not so…

A critique of the 2013 HSR study

The 2013 Phase 2 report into high-speed rail by AECOM took two years and 20 million dollars to complete, and it is a remarkable piece of work, comprising detailed alignment routes, costings, economic analysis and much more. It is easily the most comprehensive HSR study undertaken in this country to date. It’s a…

Configuring the track

Australia’s low population density means that the track length per station will be relatively high when compared to European or Asian rail networks. The upshot of this is that capital costs will greatly dominate the total cost of any railway system – the cost of rollingstock will be comparatively minor. Capital…
