I am looking to travel from London Gatwick to Bath later this month. On the Great Western Railway (GWR) website, I have the option to purchase this trip as a single continuous journey. However, the itinerary involves taking the train from Gatwick to Farringdon, then taking the tube from Farringdon to Paddington and getting on another train there to Bath.
Has anyone done a similar journey? I am wondering how the transfers work - do I scan a single ticket barcode at both Gatwick and Paddington? The GWR website also seems to suggest that the Tube ride between stations is included but I've seen some suggestion elsewhere that this isn't true - does anyone have experience with this?
