Rachel’s infertility
The Girl on the TrainRachel Watson’s infertility is an unexplained inability to conceive that shapes her sense of self, her marriage to Tom Watson, and her relationship with alcohol. The book presents it not as a single medical episode but as an accumulating loss: one made private by its causes, yet repeatedly exposed to public questions and comparisons. Rachel’s later ability to sit near a playground and watch children marks a modest but meaningful change in how she lives with that loss.
The Experience of Infertility
During a break from police interviews, Rachel takes a ham-and-cheese sandwich and a bottle of water to the small park in Witney. Mothers and childminders watch over children in its asphalted playground. The ordinary scene recalls a future Rachel had once imagined for herself: bringing her baby there, choosing a buggy, and spending time among children’s clothes and educational toys. The contrast between that anticipated life and her present circumstances gives the park scene its force; she is there without the child she had pictured, but can now remain near the playground rather than flee it.
No doctor has explained why Rachel cannot become pregnant. She remembers being young and fit and not drinking heavily while she and Tom were trying; she also understood Tom’s sperm to be active and plentiful. They could afford one round of IVF. The treatment was unpleasant and unsuccessful, and its failure had a larger consequence than either of them had been prepared for: Rachel says it broke her, and that she then broke the marriage. Her account distinguishes infertility from miscarriage. She did not lose a pregnancy; she was unable to become pregnant at all. That distinction matters to her experience of grief, which concerns the absence of a child she had hoped for, rather than a pregnancy she had once carried.
Social Pressure and Isolation
Rachel’s distress is intensified by how often other people make childlessness a subject of conversation. In her thirties, she encounters pregnancy, births, and first-birthday parties among friends and acquaintances, alongside recurring questions from her mother, friends, and colleagues about when she will have a child. Conversations extend even to what she and Tom are trying and whether she should have another glass of wine. A deeply personal uncertainty becomes familiar public material, discussed as if others were entitled to assess its progress.
Rachel feels that responsibility is placed on her. She resents being treated as the person who has failed, as though she alone were letting down the marriage. Tom’s later ability to impregnate Anna sharpens that perception and changes how Rachel interprets the couple’s earlier difficulties: she concludes that she was wrong to suggest they should share the blame. The evidence establishes Rachel’s conclusion and the contrast that prompts it, not a medical explanation for her infertility.
The loss also strains Rachel’s friendships. Lara, her best friend since university, has two children in quick succession; Rachel cannot bear to hear about them or be around them, and Lara eventually stops speaking to her. At work, Rachel finds herself unable to engage with a colleague after hearing about the colleague’s abortions. The resulting awkwardness is noticed by others. These encounters show grief narrowing Rachel’s social world: other people’s experiences of children and pregnancy become difficult for her to face, while her withdrawal further isolates her.
Marriage, Grief, and Drinking
Tom wants to be a father, but Rachel understands that he does not experience childlessness as she does. He believes they could be happy without children, whereas she cannot stop mourning something she has never had. Their difference is not simply a disagreement about whether parenthood would be desirable: Rachel describes an absence that Tom cannot feel with the same urgency. Their shared IVF attempt does not make the loss equally shared in its emotional consequences.
Rachel traces a worsening cycle between loneliness and drinking. She starts drinking more as she feels isolated; the drinking then makes other people less willing to be around her, deepening the loneliness. She does not present infertility as a complete explanation or excuse for her drinking. She acknowledges that she already liked alcohol, while describing sadness as a condition that grew more consuming and difficult to live with. In her account, infertility belongs among the pressures that intensify her drinking, but it does not erase her own recognition of responsibility for it.
Change and the Possibility of Motherhood
By the time Rachel sits beside the playground, she says she is better able to face the subject than she was a few years earlier. Then, a crowded supermarket filled with mothers and children could make her abandon her shopping trolley and leave; at her lowest, the longing felt overwhelming. Now she can watch toddlers at play. That change does not mean the wish for a child has vanished, or that the grief has been resolved. It shows that Rachel can encounter reminders of what she missed without responding as she once did.
Rachel has read books and articles and believes she must come to terms with her infertility. She can imagine a possible route to adoption if she gets herself sober and puts her life in order, and she notes that she is not yet thirty-four. These are possibilities, not outcomes: the passage does not establish that she adopts or that she has a child. Their importance lies in the future they allow her to consider. Against the earlier assumption that childlessness has foreclosed any meaningful life, Rachel begins to hold open more than one possibility.
Narrative Significance
The park gathers the subject’s central contrasts into one concrete scene: Rachel’s imagined baby against the children actually playing, a remembered inability to approach families against her present capacity to stay, and an unresolved longing against the tentative prospect of adoption. The account also refuses to reduce infertility to a diagnosis. Its cause remains unknown, while its effects are made legible through treatment, social scrutiny, marital strain, disrupted friendships, and drinking.
Rachel’s infertility is therefore both a bodily uncertainty and a lived social experience. Other people’s questions make it public; the absence of a child shapes how she reads her marriage and herself; and her later effort to imagine adoption suggests a change in possibility rather than a simple recovery. The narrative gives that change scale through a restrained measure: she can sit in the park, near the children, and stay.
