This LO is about American Sign Language and its "only" idiom "TRAIN-GONE" which translates into one or two things:
1. You've tried to join a conversation after the bulk of it was over, so you're too late for someone to re-tell you everything.
2. You're lost in a conversation/lecture.

I guess in English the idiom would be "Too late" idk... it's too hard to translate idioms from one language to another!!!
