Hey, everybody, let's play a new game on the T: Musical trains

OK, so we know it was pretty bad on the Orange and Green lines this morning. But how awesomely bad was it? You have to read Some Assembly Required's account of the mishegas at Wellington:

... The train sat for a minute, and people were starting to wonder why it didn't go on its way. Then the PA announced that this train WAS going back to Oak Grove after all. Everyone oozed grumpily back out of the train and onto the platform, including all those who had been on the train to begin with, and shortly after a second, empty train came in on the opposite platform, again from the "wrong" direction. The PA announced that THIS train was the one going into Boston, and everyone oozed onto that one. I continued to wait and observe, and both trains continued to sit.

After a minute or two the PA guy, who by this point was probably starting to really hate his day, informed us that BOTH trains would be going into Boston ...
