another power problem on the Riverside Line - with buses replacing streetcars between Reservoir and Riverside. Here's the official alert:
Alternate shuttle bus service will replace Green D-Branch trains between Reservoir and Riverside Station due to a power problem. Please expect significant delays and seek alternate transportation where available. Ã‚ 9/7/2012 7:42 PM
Note that the MBTA has posted this exact same alert about the wire problem at least four times since 6:20. They obviously don't understand that people don't need to have their phones on to get messages.
