Three motors moving the point rails


Five motors needed for the swing nose

Some kind of measuring tool


Apparently this is the method used on HSR, very different from the method used on conventional railways




Electric fastening tool


Took three days to finish one turnout

Is that the speed applicable to diverging track?

Yes. I suppose the straight track has the same designed speed as main line or sometime higher for future speed upgrade.
It seems all the turnouts used on this line have 250kph permitted speed on straight tracks.
On the other hand, the turnouts installed on Shenyang-Dandong PDL and Harbin-Qiqihar HSR(just changed name from PDL to HSR) have 350kph permitted speed on straight tracks.

I'm amazed at the skill of these workers to build the network so fast without mistakes. Who ever is the project manager(s) for this is doing a great job coordinating everything.
