This is a photo of a D train headed downtown, taken from the northbound platform (I was on my way to the Bronx to visit this cat and his servants). Thanks to the miracle of the internet, I can tell you that this is an R68 car built by Westinghouse-Amrail around 1986. It is 75 feet long and 10 feet wide. Fascinating, no?
