Boblothrope tried and failed to get any information out of the T last night why Red Line service was all bollixed up at Harvard. After 20 minutes with no inbound train:
I pushed the INFO button on the customer service phone. The phone autodialed what sounded like 2422, and nobody answered. Then it dialed another number (2423?) and someone who identified himself as "North Station" answered. He didn't know anything about the delay, and said there would surely be an announcement explaining the problem.
After another 10 minutes (with no announcements), a train came in going the wrong direction on the inbound track, dumped its passengers, and reversed to become an inbound train back to Boston.
