Curious, what do they use to lay the tracks? I'm sure there's got to be some automation.

It should be 350kmh,but adjusted to 250kmh,this line is too difficult,tunnels take nearly 80% of the length,almost an underground.the west of baoji is all 250kmh

There are machines for placing the bolts. Final fastening is done by hand machines (second picture from above, worker on the right). Of course, for the sake of the official ceremony last meters were completely bolted by workers.
For almost 1800 km of double track this means at least 25 million bolts if we approximately include stations.

Glad they came to their senses, building a 350km/h PDL in a sparsely populated region of china is a huge waste of railway funds. Even 250km/h is a bit much for me. Now that this political project is almost over lets get back to the real network in the east.

Interesting, I didn't know Xian-Baoji was nearly 80% tunnels. So only D trains between Xian-Baoji? It's a short route so I don't think the difference between 350km/h and 250km/h should make much of a time difference. I haven't done the math.

Xian-Baoji is flat open country and appears to be 0.0% tunnel. D trains are currently running on the 160km/hr standard line.

Baoji-Lanzhou will be 80+% tunnel. Lanzhou-Xining has opportunity to make as much or as little tunnel as they want. Thru the mountains north of Xining is 180km probably 80% tunnel.

Then from Minle to Urumqi is 1450km with maybe 20km tunnel max, unless you count the wind sheds.
