UPDATE: A second Red Line train died at Alewife; another Green Line trolley gave up the ghost, bollxing up outbound C and E service. Commuter rail? You don't want to know.
In this young year, the Red Line is now 2 for 2 in morning-commute delays due to dead trains, this time at JFK/UMass, but today has the extra bonus of delays due to "weather-related issues."
Meghan C. reports  it took her 75 minutes to get from Braintree to MGH.
The Green Line was also having problems, due to a recalcitrant train at Kenmore . There was also a dead train on the Blue Line.
It was a different story on the Orange Line. At 7:24, Joe Growhoski tweeted :
