Using the verbs "Leave" and "Move" when it comes to a vehicle

Question

Let's suppose it's 5 o'clock in the afternoon and you're in a train that will leave at 5:30. Someone calls you and asks if the train has left the station or it's still there. You reply:

No, the train has not ....... yet.

a. left (the usual way to say that)
b. moved (I need to know whether this verb works here too or bot.)

Then the same person calls you at 6 and wants to make sure if you have left the source or you're still there. You answer:

Yes, the train ........... at 5:30 sharp.

a. left (the usual way to say that)
b. moved (I need to know whether this verb works here too or bot.)

Answer 1

At 5 o'clock we would say the train has not left, and at 6 o'clock we would say it left at 5.30 sharp. We would not use 'move' because it might mean that it moved within the station without leaving.

Answer 2

It would be fine to say "The train hasn't moved yet". It is a bit of rhetorical emphasis. "The train hasn't left, it hasn't even moved an inch"

It would be odd to say "The train moved at 5:30". It suggests that the train moved a small amount, but remained in the station.
