An underground moving sidwalk between Barton and Hunter would cost much more than extending the TH&B line to the North-East I reckon.
Instead, I would like to see Hamilton deploy an automated-taxi system like
Ultra or
Vectus. You have to see the videos to believe them. I think the technology is finally here!
Long-term thinking of course. Lets get the A-Line and B-Line LRTs built first!
