Ironic, people bash the Commonwealth for wasting billions of dollars on the Big Dig while bashing the MBTA for not wasting of billions of dollars on electrification. Pure hypocracy. Not surprising to see the biggest advocates for electrics and bashers of the MBTA for not buying them as soon as the first wire was strung up are those who will not have to pay a dime for them...
I don't recally anyone really "bashing" either entity in this thread. I certainly understand why the MBTA hasn't bought electric motive power or EMU's. But I think it is something that should be considered to make sure the agency isn't taking a narrow minded "this is the way we've always done it" approach. Or worse, the "this is the big new thing" approach, so we'll do it even if it doesn't quite fit. I don't bash the idea of the Big Dig, either. Lack of management oversight, perhaps, but I actually think the transportation and urban planning initiative are quite enlightened.
I'd like to see the Somerville/Medford Green Line come to fruition first, for sure ...
Ok, enough dreaming....
That's probably the correct attitude -- dreaming about something is definitely not "bashing" anyone for not doing it. But it is both fun to dream, and a good excercise for generating other new (and potentially more feasible) ideas.
