ScotRail ticketing staff have highlighted further anomalies which they say can help passengers save money.
They include return trips on the flagship Glasgow to Edinburgh route, in which the return leg is on a different day to the outward journey.
By purchasing a return a return, Anytime, ticket to Inverkeithing – but getting off at Edinburgh – passengers can save £3.30 compared to buying two separate singles.
This is because return tickets between the cities are only available for passengers returning on the same day, but longer trips allow returns over several days.
One ticket seller, who spoke on condition of anonymity, also said the best fare for travelling between Glasgow and Dundee using an Anytime ticket with no restrictions was £22.50, saving £3.80, if the journey was split into Glasgow-Perth and Perth-Dundee.
