TRAIN - GONE:
“What does “train-gone” mean? Deaf people use this sign to mean "you missed it" and we aren't going to take the time to rehash the story so you can know what we are talking about. You might see this sign if you show up in the middle of a conversation or near the end of a conversation and ask what is being talked about.

If you mean "train" as in practice and get ready for an event, see "PRACTICE."
