Why am I allowed the 9.27 am train to be considered out of peak time

by Mrs R N
(Berkshire)

My daughter is a patient at UCL Hospital, London. She is

having regular appointments and has had for the last year.
Myself or my other daughter accompany her. Sometimes her
appointments require the 9.27 am train from Windsor and Eton
Station (us boarding at Datchet), sometimes, according to times
of appointments, after that time. We have only just acquired
a discount railcard, mine being a Senior railcard, hers not.
Why am I allowed the 9.27 am train to be considered out of peak
time and she NOT.

On one of these journeys recently, we arrived at the station at
the same time as the train. I asked at desk if we could pay on
the train as no time to purchase ticket and was told NO as it was not busy and could be monitored by CTV camera, thus having to wait for the next train and my daughter's appointment made even more stressful.

Sorry, these comments are not about cheap train tickets.

Thank you for reading this.
