According to the Boston Globe, the Chinatown, Downtown Crossing, and South Station MBTA stations have been evacuated due to an electrical fire. Red and Orange Line service has been stopped in the area. No injuries have been reported. Substitute shuttle bus service is being provided.



I was leaving Downtown Crossing right before the fire dept went down. A transit cop gave them directions to the unidentified smoke that would lead them to the Oak Grove bound platform.
It seems as if the shuttles at Park Street took a little while to show up, but there were more Green Line trolleys destined for Lechmere than usual.
The Orange Line is shuttered between Back Bay and North Station. If you're heading to Oak Grove from south of North Station, find a Green Line train to North Station and transfer.
