I'd imagine after the monorail crashing into the basement of Wayne Tower taking out some structural columns, and with the destruction of that rail line, both would have been undergoing vast repairs. Hence another building being used for Wayne Enterprises in the meantime. Also, the virals mentioned on the Rail site which lines were no longer in use/under repair or whatnot, and the one to Wayne Tower was one line.

All in all its no big deal, but a slight reference or glimpse during the film wouldn't have been to much to ask for.
