Red Line slower by more than a smidge due to work on the Longfellow Bridge

The MBTA tells Adam Castiglioni why Red Line trains were particularly slow over the Longfellow this morning:

Our Track Department performed maintenance work involving inspecting rail and tamping ballast at the northbound end the Longfellow Bridge. After this type of work a speed restriction is usually put into place. It is expected to be lifted after service tonight.
