Greater Boston's public transit system is experiencing widespread delays due in large part to temperatures in the single digits.
Several MBTA subway lines and commuter rail lines were experiencing delays Friday.
The Boston Fire Department briefly cut power to the Red Line to deal with a trash fire, affecting all trains.
Shuttle buses had been replacing some Red Line rains to allow for snow removal and track maintenance in anticipation of more snow this weekend.
Trains were canceled and delayed because of mechanical problems and switch issues.
The MBTA says all bus routes are experienced weather-related delays.
Temperatures in the Boston area are in the single digits and the wind chill is making it feel below zero.
