On Thursday, the #MBTA released for public comment their SFY25-29 Capital Investment Plan, or CIP. (It's important to specify state fiscal years, because the Boston Region MPO, which is responsible for allocating federal transportation funds, uses the federal fiscal year, and the last three months of FFY24 are in SFY25 just to confuse everyone who's trying to cross-index programs and budgets.)
