Buses are running along the Riverside Line this morning after a tree tried to plunge to the ground early this morning only to be stopped by overhead wires. The C and E lines had issues, too, if not of the tree variety.
A Lowell Line train suffered a "slow-speed derailment," so good luck on that line.
A train died on the Red Line somewhere between Charles/MGH and Kendall (so, on the bridge?).
