Which accounts for both expansion and maintenance / modernization

Even if we assumed all the funds earmarked for both maintenance and expansion went to the MBTA's maintenance shortfall, we're still short more than 3 Billion dollars at minimum, the MBTA needs more money

The approved capital budget says

>This $13 billion capital sources gap does not include sufficient funding to reduce greenhouse gas emissions nor to protect MBTA’s infrastructure from sea level rise and storm surge. Factoring in climate change costs, the MBTA is short approximately $20 billion for the period from 2023 through 2031. The federal infrastructure bill, if passed, will not meaningfully change this shortfall.

How do you propose we address this $20B capital shortfall (not even the operating shortfall which runs approximately half a Billion per year) the state itself acknowledges exists when making its capital budgets without adding more money and/or revenue
