Metropolitan Diary: An Exhorting, Informing, Bewildering Electronic Subway Sign The subway now has electronic signs, exhorting, informing, bewildering. This is a literal transcription of an electronic sign at the Avenue of the Americas-34th Street Downtown subway stop. All spelling, capitalization, line breaks are as found. My only editing was to take the first line, capitalize it and make it the title.
