Late last night, at the corner of 178th and Broadway near the George Washington Bridge, a truck transported a shiny new subway car into the city. Where was it coming from, and where was it going? Is there an initiative to clean all subway cars so that they shine, in the parlance of Miss Hannigan, like the top of the Chrysler Building? And most important, is that why our C train is diverted this weekend? We may never know, because obviously, the people at the MTA never answer their phones. But nonetheless: What a magic moment.
