UK train tickets come in many forms. With an Anytime Day ticket you can leave and re-enter stations between your start and end points as often as you like that day. For example, travelling from city A to city D, you can get off in towns B and C along the way — so with a well-planned itinerary, one ticket can cover several places.
It is not always the cheapest option; time-restricted fares can be better value. Still, it is useful information when you plan.
