Gov. Charlie Baker’s administration has spent three years whipping the MBTA into shape. Costs have been pared back and revenues have been increased -- all so more money could be invested in long-range improvements.

But as the race for governor starts to heat up, Baker finds himself asking riders for more patience, saying his administration is dealing with decades of neglect at the MBTA. The governor called last Wednesday’s derailment, which knocked out the Red Line between JFK/UMass and Broadway stations for most of a day, not acceptable. But he promised big improvements over the next few years, particularly on the Red and Orange Lines.

On the Codcast, Setti Warren, the former mayor of Newton and a Democratic candidate for governor, and James Aloisi, the former secretary of transportation, said the MBTA needs to address its problems more quickly and more forcefully. Both called for more revenue for the T and both faulted Baker and House Speaker Robert DeLeo for resisting that effort.
