Commuters on the MBTA's Green Line are being warned about severe delays Tuesday morning.
The MBTA says there's a disabled train at Boylston. It's unclear when the disabled train will be moved or what caused the train to become disabled.
MBTA riders took to social media to express their frustration over the delays.
Ross Ballantyne tweeted, "the green line is an absolute disgrace."
Shaun Crimmins added, "Thank you @MBTA green line for reminding me why I don't book 9am meetings."
"I've been sitting on a disabled Green Line train for 30 minutes at Copley. Please stop saying "we will be moving shortly" every 2 minutes" Andrew Oak posted.
