IMO any assumption that the victim could have been unaware of the train is too much of a leap. So (opinion) there are two possibilities remaining.

1- she knowingly was racing to beat the train and miscalculated, or
2- she was attempting suicide by train, so as to have plausible denial of her intent.

In the absence of a reason for assuming the second, I'll assume the first, but I won't assume or accept that she wasn't aware of the train, earbuds or not.
