Let's speak plain: this was a works project.
They're fine if properly administered and implemented, but Kenmore was flawed at every juncture: design, planning, execution, use. The cost overruns guaranteed a low ROI, and it now stands as a poster child for the pervasive culture of waste and mismanagement by the MBTA (and their contractors).
It sunk into a Lewis Carroll-esque farce when the success of the Red Sox was blamed for every subsequent delay.
And, with still a year of work to be done, blade, there is NO noticeable improvement (this was all rescoped and trumpeted as a way to provide ADA access to the platforms? There's still no elevators!)
EDIT: adminstrated and implementated are not words. sorry, i just watched this comedy by Oliver Stone about a president with pronounciational issues.
