BOSTON (WHDH) - Smoke billowing from MBTA Red Line tracks led to some delays Friday night as crews responded to an area close to the Charles/MGH stop in Boston. 

The MBTA first announced around 9 p.m. that trains might stand by at stations due to reports of smoke. The T later said the scene had cleared as of around 9:30 p.m. 

Video taken by a passenger in the area showed smoke as riders got off a Red Line train at Charles/MGH. The passenger said there appears to have been a fire under the train, adding that there was a strong smell.

Officials commented Saturday morning that the smoke did not emanate from the Charles/MGH station, but instead came from under the Longfellow Bridge.
