Someone on my site has hit an issue with a day travelcard issued on a Greater Anglia smartcard for Amersham to zones 1-6. It worked fine at all Met stations except Chesham, Croxley and Watford (the ones not on the direct route from Amersham). It didn't work at Brentwood either. They said:
Has anyone any idea what route R40232 means and/or if there is another route that should be being used?I checked the smartcard at a POM at Harrow and the origin is given as AMSHAM, destination R1256, and route R40232.
