The MBTA is experiencing some more problems Friday, with riders forced to walk through a tunnel after a power issue on a Green Line train.
Shuttle buses are replacing trains between Kenmore and Government Center because of a power problem, the MBTA said shortly before 6:30 p.m. in a tweet. The agency later said in a statement that three trains, each carrying about 100 people, were "unable to move within the tunnels between Hynes and Kenmore."
Around 8:30 p.m., the MBTA said service had resumed with delays of about 20 minutes.

Earlier Friday afternoon, Blue Line service was also replaced by shuttle buses between Orient Heights and Wonderland. The MBTA said around 6 p.m. that service had resumed with delays of about 15 minutes.
Also, on the Red Line, smoke spilled from a train into the Andrew Square station. Riders had to get off that train around 6:30 p.m. and take the next one toward Braintree.
The incidents come a week before the entire Orange Line shuts down for 30 days starting Aug. 19. Beginning on Aug. 22, the new Green Line extension will also shut down through Sept. 18.
The MBTA released its plan Friday for travel alternatives. "A Rider's Guide to Planning Ahead" details the shuttle bus and Commuter Rail options that will be available.
