Earlier today, the Red Line bypassed Park Street Station and the Red and Orange lines bypassed Downtown Crossing Station. Both the Red and Orange lines were back on regular service by around 5:45 p.m.

The Blue and Silver lines and the Red Line to Mattapan were unaffected by the incident.

Customers who needed transportation in the Back Bay and downtown areas were told to use the Orange Line to Back Bay and Chinatown stations and the Red Line to South Station, according to the MBTA website.
