An inbound Red Line train refused to go past its expiration date at Wollaston, causing what the T called "moderate" delays at the start of rush hour this morning. Or as Sara put it:
Been waiting over 20 min for a train at #wollaston. #commute #freezing
UPDATE, 9 a.m. Another Red Line train saw a bright white light, this time at Harvard, and immediately caused what the T calls "severe" delays. Signal problems at Boylston plunged Green Line riders into a snail-like existence.
UPDATE, 9:20 a.m. Green Line train taken out of service at Packard's Corner due to brake problems.
