If you mean 'What preposition would you use to describe train travel?' the answer is 'by': 'I will go by train when I visit my aunt in Edinburgh.'
However, 'train' has other meanings, for example, to prepare for something. In that case it is a verb, not a noun. So you would say 'The athlete will train for the Olympics.'
You will get a much better answer if you express your question as a complete sentence. It is also more considerate towards the people who you hope will help you. I have made two guesses at what you might mean, but both of them may be wrong. I should not really have to spend time guessing what you mean.
