A film heavily using train tracks as a setting piece and taking place somewhere in the UK. It follows a father introducing his young daughter to his other small child- a result of an affair (though I think this was more heavily hinted towards the end). The two girls are rather disagreeable through most of the film. It may possibly be a short film rather than a feature length piece. I think the film may have possibly used a holiday as a backdrop, either Christmas or Easter. I know for certain that the director was a woman.
