Hi I am planning to visit Birmingham tomorrow from london. My coach will drop me at Birmingham NEC and I have to reach New Street Station. I don't know how far they are. I have to take a bus from there to reach to my destination which also will take almost 40 mins. Thanks.

How do I travel from the NEC in Birmingham back to Swindon? Do I need to travel back to New Street station or do I get on the train station at the NEC? If so where does that go? Thanks.
