And I wonder if those in other cities planning at-grade light rail are wishing they could be more like Boston and get awesome tunnels.
Why is it that other US cities in Miami's size category are planning tunnels, but Miami is opting instead for expensive and inefficient streetcars with tons of grade crossings? Is Miami that provincial and out of touch?
I'm sorry, I've gotta call B.S. on this one. Being from South Florida, and being very aware of SoFlo politics, I insist on shedding some light to you about Miami's dilemma. If Miami was able to, they would install a subway system. It obviously makes the most sense for heavy transit in a developed area because you don't need to worry so much about land acquisition for your system like you would for other modes of transit (i.e. elevated rail, monorail, etc.).
Unfortunately, Miami's geography prohibits subterranean construction. For the entire state of Florida south of Lake Okeechobee, the water table from the Florida Aquifer is literally 3-4 feet below the surface (which is already at sea level). This is why you don't find basements in much of the state, along with a number of reservoirs/retention ponds in suburbanized development built to strengthen the foundations for buildings.
Miami's only refuge for the foreseeable future is to bring back streetcars and install BRT at grade and on roads. It requires the least amount of land acquisition and is not nearly as expensive as extending the current Metrorail system (*which they have allotted funds to expand, BTW).
Sorry for digressing off from the real topic, though: Boston's Urban Ring.
I don't remember who said it, but they're right: if they're going to tunnel between Ruggles and Kenmore, they may as well install rail service. Just 20 minutes ago I was eating at a sidewalk cafe @ NU and counted the number of people getting off green line trains vs. the 39 bus.
Between 5PM and 5:30PM @ the Huntington Ave. Northeastern University T stop:
4 green-line trains ==> 46 total passengers getting off trains.
6 T Busses (RT 39) ==> 18 passengers getting off busses.
It doesn't take a rocket scientist to realize that Bostonians (and the masses for that matter) prefer rail-oriented travel over bus.
