Where is Tom on the train in Professor Layton and Pandora's Box?

Tom is not a boy he is a dog, and you will eventually find him on the observation deck on the train. you first have to pick up his hat in the kitchen, and his shoe in the hall.

Look on the balcony. If you can't go there, there might be a person in the hall. Talk to that person. I'm not really sure because I have the American version. I hope I helped!
