I need a word to describe whether a train is "departing from" or "arriving at" a specific station.
Q: Excuse me. Do you know the [***] of (or between) train T01 and station S02? (asking if the train T01 is departing from or arriving at the station S02)
A: Yes, The train is arriving at station S02.
What is the word [***] that most describes such situation?
Single word is preferred.
