With that, you use the word trainsite as your account name on at least youtube, which is another keyword domain you don't own. Maybe google thinks you are about trains that drive in the rain?

You have to create the authority for your name, prob best to use social networks to help create a social brand for yourself as well as something to cross link and share other things with. And if possible change whatever you trying to brand to something more unique, allowing you to own the domain too.
