The derailment on the Red Line in June may have been a turning point.

After Gov. Charlie Baker visited the crash site, he decided it was time to accelerate repairs on the MBTA and greenlight more shutdowns of the system to speed up projects. The derailment also galvanized the debate over new transportation revenues – for the MBTA and the state as a whole.

The state’s business organizations weighed in last week on the new revenue issue. Several wanted no part of a tax increase and there was scattered consensus on what taxes or fees to raise among those calling for additional transportation revenues. But Jim Rooney, the president and CEO of the Greater Boston Chamber of Commerce, and long-time government analyst Michael Widmer said on the CommonWealth Codcast that the derailment and continuing problems with the T have helped build a case for additional funding.
