Rail will be reliable, with predictable arrival times. Only grade-separated transit delivers riders to their destinations on time, every time.
Since rail will run on electricity, it eventually will use “green power” as our society transitions from fossil fuel to renewable forms of electricity generation – wind, solar, municipal waste, ocean thermal energy conversion, biofuels and perhaps others. Rail will reduce pollution and be a natural market for renewable energy.
The anti-rail opposition generally avoids addressing those issues head-on. Citizens still searching for answers on the project might well ask opponents about them.
