Other than to change trains, a break of journey at intermediate London Underground or DLR stations is not permitted.

Your ticket is refundable.

If you wish to change the date of travel, or the origin or destination of your ticket, it may be necessary to buy a new ticket and apply for a refund on your existing ticket (see Refund Policy).
