I've never ever been on a tube before and I'm so worried about it! If my journey goes wrong I am literally knackered as I'm getting a train from London to Northampton.
Heres my journey pic:

What I'm worried about is the Arrive and Departure times. Some are at the same time of arrival. What does this imply?
Thanks.
