The On-Route Principle
The primary concern of those travelling is staying on a route acceptable for the ticket they have purchased. The customer is always on-route if they can answer yes to at least one of the below, according to section A of the guide:
- Is the train an advertised direct train from origin to destination?
- Is the customer on the shortest (by distance) route between origin and destination? (according to the mile distances listed in the National Rail Timetable, in theory, though not always in practice.)
The full routeing guide is consulted only upon answering 'No' to both questions. This can occur when the customer wishes or needs to change trains several times, either with a view to travelling on a particular line (for example to connect with a faster train), or because of a desire to break a journey at a given station not directly on the 'expected' route.

Famous quotes containing the word principle:
“The principle of avoiding the unnecessary expenditure of energy has enabled the species to survive in a world full of stimuli; but it prevents the survival of the aristocracy.”
