I am new to this site. Just retired from 48 years in the bus industry. Schedules and route planning. On the topic of rail fares I find some strange anomalies. I was booking a return from Batley to Bentham with Senior Railcard. Price £ 16.35. If I book an extra 5 stations to the Morecambe terminus and an extra 5 back the return price is £15.50. Where is the logic in that?
