Time restrictions for tickets are sometimes specified by referring to a specific service and this can lead to incorrect restrictions being specified if the train moves by as little as a minute in a timetable change.
For example, the 09:05 from Foxton to London was re-timed to 09:04 in December 2013, but the restrictions still refer to 09:05.
In this case £21.60 Off-Peak Day Return is not shown as valid on the 09:04, although the £34.00 Off-Peak Return is shown as valid presumably because this has been corrected by one minute (although the text description shown later would imply not).
Below is the current description of the restrictions from http://www.brfares.com/ “as of 19 January 2014”. It raises the question: does the rail industry have an automatic way of identifying these timetable related issues, or is it a completely manual process?
