The Massachusetts Taxpayers Foundation has been warning for some time that funds for capital spending at the T are going to start falling off a cliff in fiscal 2025. The T didn’t dispute the foundation’s numbers, but also didn’t produce its own estimates – until Monday. Using the T’s new numbers, capital spending is forecasted to hit $1.9 billion in fiscal 2022 and then start dropping – to $1.7 billion in fiscal 2023, to $1.3 billion in fiscal 2024, to $1.1 billion in fiscal 2025, $984 million in fiscal 2026, and $898 million in fiscal 2027.
