From next Saturday, 2nd January 2016, holders of 5-10 zip cards will no longer need to pay for any National Rail journeys within the zones. This is good news, but what if you already have some credit on your card. The helpdesk can arrange a refund, but a side-effect is that the card will be cancelled. As you need the card to benefit from the free travel that is obviously no good. There appear to be two options available at the moment:
- Take the 5-10 zip card to an Underground station and ask one of the staff on the concourse for assistance. They can (I am informed) refund PAYG credit using staff functions on the ticket machine without cancelling the card.
- Leave the credit on the 5-10 zip card and when you apply for an 11-15 zip card it will be transferred to that.
If you rarely visit an Underground station and/or your child is nearer to 5 than 10 then you appear to be stuck. This is not ideal and I have asked the helpdesk to pass the issue back to see if anything can be put in place for the next few months.
