Let's just take a moment to look at the visual design, though (not that it negates any of the above concerns). Those sleek silver pods, the gigantic, exposed machinery in the upper station: it's like a tiny bit of an early 20th-century idea of technological utopia (or would it be a dystopia?) has landed in South Portland. There's a terrific and detailed discussion of the tram's design and possible roles in the public consciousness here.
Wikipedia tells us that funiculars were considered an early alternative option to the tram. Don't you kind of wish we had those in our fair town as well, be it trotting up and down Pill Hill or elsewhere?
