Rich and Strange Aeons

The bulb thing is what I called an electronic line map.

Last T trains are before 1am. Yeah, having some 24-hour service is a rare feature of NYC; the only other one I know of is some lines in Chicago (Red, Blue, maybe Green, certainly not Brown when I lived there.) The usual explanation is that only NYC has enough spare track to shunt running trains around while doing maintenance (I dunno Chicago's explanation, though much of the Red Line has extra track due to parallel lines.)

Of course, the L line I was staying along was shut down at 11:30pm for a week for work. I avoided seeing how long the replacement shuttle buses could take.
