awesome, but why not make the tracks ballastless and the catenary a 3rd rail?
also, the catenary poles don't at all match the architectural style of the building

but still

I think that for high speed wire is more suitable than rails. And in a country where the ground is prone to occasional movement ballast less tracks might not be such a good idea...

There's a compatibility problem: we have no 3rd rail trains, and to buy some would be quite more expensive than using overhead wires.

And K_ is right as well. Have you ever seen High Speed railways with 3rd rail?

The poles should hang from the ceiling like most covered stations.

Impressive. Not sure I'm too fond of all that tunneling, as one of my main pleasures with rail is looking outside, but some engineering!

The railway is already operating (and it has been since 2009).

Japan is one of the most earthquake prone countries in the world and guess what: A large percentage of the Shinkansen tracks is ballastless, because of it's lower maintenance costs and better resistance against earth quakes...

HS trains can't be supplied with third rail

The TGV Transmanche (for Eurostar) in the past ran under 750 V DC third rail, but with a speed limit of 160 km/h or less.

Well, third rail at ground level seems to have different limitations compared to centenary rail... Maybe due to differences between collecting shoe and pantograph?

HST can go on 3rd rail, but they cannot work at 300+ km/h, since DC is not really suitable for those speed and those electicity absorption. Here in Italy, from Rome to Firenze there is 3kV DC and the max speed is 250km/h. From what I know, to go at 300kph you have to raise both pantograph and doing so will increase consumption and will ruin all the equipments faster.

An interesting remark: despite all doomsday predictions that Italo would go bankrupt, or that lack of connectivity with other railway services would reduce demand, or all rumors that SNCF would quickly buy Italo, the company is doing okay and its services have raised the bar for Trenitalia.

The "OMG the AGVs will start to break down in 6 months" rumors were also disproven.

Which rumors? As far as I can see nobody (at least nobody with credentials in the rail industry) dissed the AGV.

You're sure you're not just imagining things here?
