Good evening. Could anyone advise me as to the best way to add my 16-25 Railcard discount to my oyster card? According to the TfL website, to do this I should: Ask a member of staff to add the discount to my oyster card; Show them my Railcard. However, generally the only members of TfL staff I see are gateline assistants of platform dispatched, both of whom I assume have better/more important things to, and don't have the means to do so anyway. TberefoTh, whom do I speak to? Are there any particular stations where this is easier to do? Do you have any other advice for me? I will be in London tomorrow, arriving/departing from Paddington. Many thanks for any replies.
