Ideally, there would be an exit from the train station onto Kimpton Road but it doesn't seem to exist.
I think this is being constructed at the moment, as it will also provide a very short link from the station to the new Hampton hotel currently being built on Kimpton Road, next to the station. Once the construction phase is complete, and the hotel opens, sometime in December I believe, the Kimpton Road exit will be opened to the public. That is my understanding anyway.
