A small clip from an email from one of her friends:
Sandie loved trains very much, in fact that was the only thing she ever really played with on the computer apart from a few car racing games as well, and I know all the stuff you sent her gave her hours and hours of pleasure and happiness.
So I personally would like to say thank you to you for making her so happy.
Sandie never saw trains as a game though, she said it was more like a way of life.
