Update: At 8:35, the T was reporting 25-minute delays to somebody on the tracks at JFK/UMass.
At 7:22 p.m., the MBTA reported 20-minute delays on the Red Line due to a deceased train at Andrew. At 8:19, Adam Castiglioni asked when the trains would start up, because he's still stuck in the system, more specifically, at North Quincy, where not a single train has come through in either direction in 20 minutes.
