A shame there's no Twitter-controlled Christmas trees at Hynes station, because that might lighten the place up a bit now that the regular lights have failed, as Derrick shows us.

Above ground, meanwhile, traffic lights have gone on strike in the area of South Station.

A Green Line inspector could be in hot water for an incident on the Green Line this morning in which a door panel on a trolley suddenly fell off the train, a spokesman says:

A Green Line inspector is facing disciplinary action for failing to ensure that the trolley door was secured in the closed position before the train proceeded to Park St. Because of his failure to follow established procedures, a segment of the door dislodged after making contact with a part of the subway infrastructure.

New England Conservatory students will play in a concert on Saturday to benefit the Friends of Boston’s Homeless and The Women's Lunch Place and the people displaced from programs on Long Island when its bridge was shut in October.

A concerned citizen does some bike counting outside the Apple Store on Boylston Street:

If there's a place bike racks are needed it's here ! Bikes attached all over the place! Maybe you can get Apple to make a large art piece for a bike rack! I'm counting 10 bikes locked to everything except bike racks!

Good thing Boston has more than one paramedic unit: Boston EMS Incidents reports that when a report of a person suffering a heart attack in the Prudential Center food court came in around 10:30 p.m., the Paramedic 1 unit stationed on Purchase Street was dispatched to the scene - but couldn't even get out of its bay due to the large traffic jam caused by protesters in Dewey Square and police blocking traffic to keep motorists from plowing into the protesters.

Dispatchers then routed Paramedic 2, based on Warren Street in Roxbury, to the mall, where firefighters and EMTs were treating the unconscious but still breathing person until the paramedics could arrive.

A Ferguson protest in Dudley Square turned into a march of people that kept getting thwarted by Boston and State Police to shut one of the highways running through Boston.

The action started at the Southeast Expressway southbound at the Mass. Ave. connector, where protesters were mostly blocked - although they shut down the connector, police kept them off the Expressway.

Matt Soleyn reports that around 8:50 a.m., a bus from Fairfield University was about a half-mile before the Fenway exit inbound:

This is a little after the fact, but I haven't seen it on UHub or anywhere else: Amtrak has closed its ticket office at Back Bay station.
