London Paddington can be reached by train from Charlbury Station in about 1 hour 30 minutes.
You can’t possibly be stuck for places to see and things to do in London but why not let someone else guide you around on a walking tour around Westminster? Having taken one of these I can say they are excellent, informative and you will certainly learn things that will surprise you. There is usually a social drinking or eating stop en-route.
