According to the Boston Fire Department, the trouble started around 8 a.m. when smoke from an electrical line forced officials to power down and evacuate Arlington and Copley stations.
By 10 a.m., the MBTA was able to isloate the problem cable.
Aside from the Green Line trouble, Newton commuters using the Framingham/Worcester commuter rail line have had to wait a big longer in the single-digit temperatures this morning. Several trains experienced delays between 20-45 minutes, including the P505 (7 a.m.), P506 (6:35 a.m.) and the P510 (7:55 a.m.), according to T alerts.
As of 9:35 a.m., the P509 (9:05 a.m.) outbound train was also experiencing 10- to 15-minute delays.
