Don’t ask me. The entire concept is based on just about everybody commuting between city jobs and suburban homes, a traffic flow pattern that doesn’t really exist anymore.
In Jacksonville, the light rail “system” I’m most familiar with, it winds up costing something like $20 per passenger mile, besides burning more fuel per passenger mile than transporting the same number of people in a car. Quite often it runs completely empty. Very bizarre.
OTOH, in Sacramento it works fairly well, but provides only limited alternatives to auto transport.
The Detroit ‘People Mover’ light rail is a total failure. Runs a loop in downtown only, around the abandoned buildings. 80% Fed built and maintained.
