Even if you think what you would say is obvious, please add. This is genuinely something I think makes sense regarding local bus routes given the longevity of light rail and how infrequently routes change, but I also suffer from confirmation bias, so I’m hoping for reasons this would be a terrible idea but obviously would prefer reasons it would be an even more amazing idea than I thought.
Light rail transit has its own right of way. Sharing the road means it’s a tram/streetcar.
Yes, technically a tram at that point, though the system has sections of dedicated rights of way too, and has recently been expanded onto some old traditional rail lines in a tram/train hybrid system.
