Elon’s Tunnel
When one engineer accuses another of having his sums wrong by a factor of 50, you can be sure that one of them has said something silly.

Metro Sydney
A 10km dual-track tunnel takes us to Central Station at 200-plus km/h – this is the most expensive sector of the railway by far, but by using existing infrastructure to a far greater extent than previous proposals, the total cost to access the Sydney CBD is the lowest of any proposal to date.
Liverpool
In our look at the possible corridors we could use to access inner Sydney, we identified two possible contenders that could get us to within about 15km of Central Station before we had to go underground. The first was to use the East Hills corridor until Revesby or soon after, and subsequently using a long tunnel (15-17km) to Central. The other main option was to use the Cumberland and Inner West corridors via Liverpool and Cabramatta…
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…
Getting into Sydney from the southwest
Access to Sydney’s city centre has always been one of the major challenges of previous high speed rail concepts. The density of existing development, the lack of suitable transport corridors and the formidable terrain mean that there is no easy way to access Central Station on a high-speed alignment. There have…
Campbelltown
The last sector before we reach metropolitan Sydney presents few design difficulties, or at least no more so than the adjacent Hume Highway. A couple of bridges and moderately deep cuttings are all that is needed to bring the high-speed railway back to the Southwest Rail Corridor, where the prevailing radius is about 1800m.
