The frozen T

This is the kind of day for which I reserve the phrase "utterly and obscenely cold." The 410 inbound train on the Fitchburg line ran 15 minutes late. Two of the cars were unheated, so passengers packed into the remaining cars. Some people got onto that train by mistake, thinking it was the 420 local which runs 20 minutes later. The Red Line subway wasn't much better; I had to wait about 10 minutes and then squeeze into a packed train.
