The yellow 65mm x 30mm Crouzet cards with 3-letter station codes are similar to those on the Métro de Paris. More logical 4-digit machine numbers (two digits for each station plus two for each machine starting at 30) appeared in spring 1986 and the range went higher with new station openings.
Monument MMT 2245 - Tyne and Wear Metro Crouzet ticket is a great product for someone looking for a ticket to explore Tyne and Wear Metro in 1990.
