Two separate incidents have troubled Wednesday morning's subway commute.
An electrical problem at the Arlington station has shut Green line service at different points for each branch of the line. Inbound service on the B branch ends at Blandford Street, the C and D branches end at Kenmore and all E branch service is suspended.
For the B, C and D branches, bus shuttles will ferry riders inbound to Government Center. For E branch riders, the MBTA recommends they take the 39 bus instead.
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.
Meanwhile, a disabled train on the Red Line has delayed service between JKF/UMass and Park Street, according to the MBTA website.
Commuters stranded in the cold took to social media to voice their displeasure.
