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:
“Whether our feet are compressed in iron shoes, our faces hidden with veils and masks; whether yoked with cows to draw the plow through its furrows, or classed with idiots, lunatics and criminals in the laws and constitutions of the State, the principle is the same; for the humiliations of the spirit are as real as the visible badges of servitude.”
—Elizabeth Cady Stanton (1815–1902)
