Tory and Christof attended those public meetings on the proposed new commuter rail lines, and have some excellent suggestions for how we can - fairly quickly and at a reasonable price - implement two such lines, both of which would be useful. I think Christof sums it all up succinctly:
If a quick commuter rail implementation is ineffective -- if it results in long, inconvenient trips, if it carries low ridership - it might cause riders and voters to give up on commuter rail altogether. So while it's nice to be quick, it's equally important to be good. Whatever the first line is, it must be effective.
