Comment on Public transit in Chengdu, China versus Toronto, Canada

Off of the remaining size of the Chengdu network after you correct for the other issues in OP’s representation.

Regardless of the ethnicity and mother tongue of the workers, smelting and extruding rebar, shipping it and pouring concrete around it is the same process. They can’t magically go faster over there, and the reason their labour seems cheaper on paper has to do with the West producing things they can’t (yet). If correctly presented, it would be pretty obvious it’s not apples-to-oranges like it looks in OP, I think.

I’m wondering WTF happened to Toronto line 3, though.

Can you please "correctly present" what about the classic Chinese cookie-cutter metro technology is deficient and 25% behind Western technology?

For why Chinese metro construction seems apparently faster you can watch https://www.youtube.com/watch?v=ehTy-qQVZhM; it's just like them Cape Cod suburbs in North America.

  I don’t have rail-specific knowledge here. It’s just generally how construction works in places like China or Laos. Many other things, too.

    Even if that is true, this is pristine underground rail!

btw as mentioned below, line 3 was cut to make way for replacing it with a line 2 extension

  Yeah, the Wikipedia article is pretty long and I can’t really make out what’s going on easily. Did they not have funding to maintain both?

    It was a tacked-on retrofit of a planned ambitious interurban streetcar network, converted to a light rail system after a lot of it was already built. The trains don't even use some of the built track. This used technology that was completely different from the rest of the network and only found there within all of Toronto. The sharp corners the cars weren't particularly designed for effected loud shrieking guitarless metal heard far and wide, loud and clear at the Kennedy bus platforms. When it came time to decide the future of the line, the planners decided to blow it up and start it anew (well, turn it into a three-station extension to Line 2); among other things, all of the above plus relatively low usage and decades of inattention prior to the "what now?" discussions made their usual maintenance unprepared and inadept. In fact, just four months before the planned closure, a train derailed due to failures of track maintenance.
