Looking at the link from Trickyvegas raises silly question 2, if a season ticket on a FCC route from somewhere outside the travelcard area to london is issued to R1256 (instead of the other option, london stations), is that an annual travelcard for zones 1-6 (including DLR, buses, tube, London Overground etc.) plus all FCC travel between the starting station and zone 6, or just all travel on FCC between the starting station and zone 6 and all FCC travel with zones 1-6.
