Explanation:

- Option 1: "in; from" doesn't fit well. "In the platform" is incorrect because people stand "on" platforms, not "in" them. "From the station" sounds odd for a train leaving.

- Option 2: "on; out of"

- "On the platform" is correct as people stand "on" platforms.

- "Out of the station" works as it describes the train leaving.

- Correct Answer: "on; out of."

- Option 3: "by; out of" doesn't work.

- "By the platform" is unusual since people are "on" platforms.

- "Out of the station" is correct for leaving.

- Option 4: "above; away from" doesn't make sense.

- "Above the platform" suggests floating, not standing on.

- "Away from the station" can describe leaving but sounds odd.
