She says she is going to throw coins onto the tracks but she doesn't seem to.

I've came back to her like 10-15 times attempting to initiate this mission but nothing. I've gone on the tracks and tried looking for coins, but nothing.

I try pressing 'A' next to her to talk, but nothing.

How do you accomplish this mission??

She will throw 4 coins on the tracks. Watch closely and you can see them fall. Then just drop down, run along and repeatedly hit the A button and you should pick them up. Do it quickly though, a train WILL hit you if you don't.

She doesn't throw anything. She just stands there.

And besides, no trains even come on those side of the tracks.

Your game must be glitching then because there is no reason why she shouldn't be throwing them and there's no reason a train shouldn't be coming. All I can say is talk to her and watch her very closely from the side to see if/where she drops the coins and do as I said in the above post. Good luck.
