 Adult tickets issued with the original Network Card displayed a status code of NSE, while child tickets showed CHNSE.These codes continued in use when the Network Railcard was introduced in its place, until the major change in June 2002.When the "new" Network Railcard was introduced, with the £10.00 minimum fare and altered child discount, there were still a large number of "old" Network Railcards in use, with no minimum fare restriction and £1.00 flat fares for children.
