We get it. You're the maglev guy. Sounds nice but we're not gaining much, if anything. We would still need guideways, overpasses, stations and other infrastructure plus the unknown switch over costs for a half built conventional system to a maglev system.
Maglev trains are built primarily for high speeds between longer destinations, not for short inner city rail systems with many stops. And they need huge amounts of electric power which is expensive here.
After all, we already have one pig in a poke, why do we need another?
