It wasn't even that much - $90M was the total remaining balance on it. Their annual obligation was ~$12M, and They actually effectively paid it off completely last year, as the T escrowed the remaining balance, falling off their balance sheet. In fact, my recollection is that the State dedicated a portion of the 2025 fair share distribution to to do so, to open up future debt capacity.

Either way, debt service is still a substantial chunk of the MBTA's total budget - yet less proportionally than in previous years, but only because the operating budget has grown substantially. That said, the agencies total debt has actually stayed pretty well checked - the T had ~$5B in debt in 2007, it has about $5.8B in debt in 2025. In absolute dollar terms, that's pretty well controlled.
