Light Rail Vehicles - LRT, ICTS, Monorail, and more

[Markster]

Not really, I was just pointing out that in general, Japan is above everyone else when it comes to transport (they have to be), and they chose elevated AGT and elevated Monorail.  So I think that says something.  I wasn't really trying to bring their HSR and Commuter Rail into it (but yes, many of those lines are elevated, too).

Well, they have one monorail, and one AGT...
And dozens of third rail or pantograph heavy rail lines...

Tokyo doesn't build Light Rail as we know it because their densities are much higher, the land available is much lower, and they're willing to put up a lot more money. They need the capacity, there's no room on the road to put in a train, and they don't need the cost savings you get at-grade. Also, Japan isn't as adverse as we are to having level crossings with heavy rail.
