I bought a railcard and registered my discount on my Oyster card using that railcard, which the discount entitlement is called National Railcard.
Afterwards, I bought an annual Travelcard on the same Oyster card as well.
In such case,
1. Do I still need to produce the original railcard used to add the discount into the Oyster card, when using the discounted Oyster card with annual Travelcard in it?
2. After I renew my discount using the annual Travelcard, do I need to bring my Gold Record Card when setting up the discount, and when I travel with it?
