Re: Green Line to Medford to start in 2011
College Ave. was indeed called "Tufts" when the short-lived commuter rail stop was there from '76-79. It'd be much better if Tufts weren't already used, because it pegs the location way better than "College Ave."...which could be anything from Powder House Sq. to Medford Sq. in walking distance depending on which end of the street. Out-of-towners are going to be much more interested in the campus, since every other big school in town has an explicitly named station on the spider map. And in-towners are going to use that as a placemarker for an alternate walking-distance stop to Davis. At minimum it's got to be a subscripted name.
Tufts Med Ctr. is bad simply because--as they've already found out--university hospitals have gotten into the same consolidation and name-changing habit as big corporate conglomerate hospitals. If it's not an unchanging century-level landmark like Mass General, this won't be the last time it has to change. I argued this in the "choose your naming rights wisely" discussion.
But...they made their bed on this, so two Tufts prepayment stations is a bad idea. The only place where duplicates or near-duplicates aren't going to confuse people is on non-prepayment streetcar stops or commuter rail duplicating a rapid transit station name.
I'd rather not mess with too many others, though, unless redevelopment or renaming conditions force the issue. It's a slippery slope. Start putting everything under consideration, and you inevitably get some that are worse than what they replaced...like the 1980's name changes on the Red Line or the over-tinkering with Auditorium-->Hynes/ICA-->no-ICA. There's got to be a really good reason to do it if it's going to be done at all.
