From a wayfinding perspective I cannot get the rationale behind trying to confuse people as to where to go with obscure names.
We're not the first system to have duplicate names. It's not a big deal, since they're on different lines. And if it really is a big deal, change the names of the stations to be unique (i.e. hyphenate as we have in the past or use a slash the way LA does).
For GO Transit, I get the "community" naming scheme and it makes sense. For local transit, as in the Crosstown, it should be street names first and foremost.
