A "power problem" between Newton Centre and Chestnut Hill means "moderate" delays, the T advises.

The Riverside Line has degraded to "moderate" delays due to a trolley mistaking its tracks for the River Styx.

Riverside Line riders are being herded onto buses this morning as T workers try to repair the damage from the tree that fell on the wires at Chestnut Hill this morning. Several bus lines are now running delayed, even aside from the snow, due to buses being diverted to the impromptu D shuttle.

Problems at Newton Highlands mean major problems on the Green Line to and from Riverside.

An inbound D Line trolley breathed its last at Brookline Village around 8:15 a.m., leading soon after to delays.

UPDATE: Tree removed, service resumed.

The T is shutting the Green Line between Fenway and Reservoir at 11 a.m. so workers can remove a large tree that is now leaning dangerously close to the overhead wires near Reservoir. Expect a two-hour shutdown.

Because substitute bus service will be limited, customers are strongly encouraged to use the closest stations along the Green Line’s C branch (Beacon Street).

Bus service will be available for persons with disabilities at Reservoir and Kenmore Stations.

A Braintree train pulled into JFK/UMass and then just sat there because the doors refused to open. Finally, workers figured out how to get people off the train.

Meanwhile, Josh Jacobs reports from a daisy-pushing trolley just past Longwood on the Riverside Line:

This ride on D line trolley 3603 is The Braking of the Riverside 1-0-3 (A.M. at this rate).

OK now someone playing Star Trek opening theme and totally trolling.

A tree limb that obeyed the law of gravity right onto the overhead power lines at Brookline Hills is causing all sorts of grief on the Riverside Line this morning.

Deirdre reports that her trolley stopped at Beaconsfield and the driver urged people to walk over to the C Line.
