It was a frustrating day for commuters riding the MBTA on Monday.
Severe delays were reported on the Red Line in both directions around 4 p.m. Monday afternoon. The delays were due to a "power problem" at Broadway, the transit agency tweeted.
Commuters shared photos on Twitter of firefighters responding to an apparent fire on the tracks.

Earlier Monday, the MBTA's Green Line experienced severe delays, as well, due to a signal issue.
Riders took to social media to share their frustration.
"It's infuriating to throw so much money at a service that rarely works and breaks daily, especially if you're cursed to live on green line," Cameron Barney said on Twitter.
