In my previous post, I mentioned how I envision a couple of rail lines linking the northern exurbs with Downtown Pittsburgh. I am changing my thinking and instead considering bus-rapid transportation for this corridor. Communities are smaller and further apart from one another. Therefore, the density is not quite there to support any heavy rail transportation.
I am, however, considering a heavy rail line along the northern/western shore of the Allegheny River to Freeport Borough in Armstrong County. I am also considering a more regional bus system extending from each rail terminus.
