A cavalcade of missteps, hazards and failures at the MBTA have prompted some public figures to call for the transit agency to be absorbed into another department or placed under federal control, but those actions would not address the deep-seated problems that have festered for years, according to a new report.

Analysts at the Massachusetts Taxpayers Foundation said the T needs to focus on its physical infrastructure, financial footing and organizational structure all at once to return to working order, pointing to impending turnover at the MBTA oversight board as a possible catalyst for change.
