There could be various reasons why someone might "maa ko train ma choda." Some possible explanations include:
The train ride was long and arduous, passing through landscapes that ranged from dense forests to arid deserts. With each mile that passed, she reflected on her life, the decisions that had led her to this point, and the sacrifices she had made for her child's well-being. The rhythmic motion of the train seemed to echo her own heartbeat, a constant reminder of the life within her that she fought so hard to protect and nurture.
