How do you differentiate fares by calling patterns?GBR will most likely differentiate fares through route restrictions, category of service and calling patterns, as well as peak/off-peak.
More realistically, the differentiation of fares over long distances will be by advance fares, with one level of anytime fares and off-peak walk-up fares removed, on the LNER model, and over short distances by peak / off-peak, on the TfL style PAYG model.
