How do you get the train to work in Pokemon SoulSilver?

There is a little girl in Saffron City in a little pink house. Go inside, go upstairs and talk to her. She will say she's missing her Clefairy doll. Leave the house and go to Vermilion City. Next to the Pokemon healing place is the Pokemon fan club building. When you go inside, a man standing next to a couch will be there will the Clefairy doll. Talk to him and he will give you the doll. Go back to the little girl in Saffron and talk to her. When you give her the doll she will give a train ticket in thanks.
