+1. Signage in NYC metro is woefully poor IME. In the London Underground pretty much everywhere you look in the carriage, there is a map or route diagram, with clear announcements and digital signage telling you where you are and where the train is going. Same with the platforms - the station name is repeated many many times everywhere on the platform and there are maps, signage and route plans all over the place. In NYC it seems that maps and signs are kept to a minimum, with some stations just having a singal initial (!) on a grubby ceramic wall tile to identify the station IIRC. The driver might mutter something over the tannoy, but if you're not familiar with the vernacular or plain just don't understand what they said, your often left confused about where you are or if you are going in the right direction.
