The transit agency says the increase in workers hitting the six-figure threshold was the result of an uptick in overtime spending due to more repair work being done in 2017.
While top earners made more, the MBTA's overall payroll for 2017 was $553 million, approximately $6 million lower than in 2016.
The report was released as the MBTA is considering a fare hike.
