Not really relevant, is it? Trains are directed by (unambiguous) lighted signals. And, last time that I checked, trains can only proceed or stop (and, very rarely, reverse course).
Poor Egypt Air was probably dealing with a complex airport chart as well as a language that he was only minimally qualified to understand. Note all the comments on this thread. It seems that even most Brit crews are quite unqualified to deal with the local language and procedures. Perhaps additional training is necessary before any non-US pilots attempt to operate into JFK.
