If you took four bus journeys and then a single zone 3 tube journey,
in that order, would you be charged...

£3 (cap for bus pass) plus £1 (single Oyster tube journey in zone 3)
totallying £4

or

£3.20 (cap removed when Oyster realises a tube journey is then taken)
plus £1 (single Oyster tube journey in zone 3) ???


If it's the above, then that's cool.

If it's the second option, then perhaps it's a good idea to have two
PAYG cards - one for buses, and one for tubes when bus caps have been
reached!

It would be the first of those two options. The 'bus cap' would remain
and a further £1 would be deducted for the Z3 tube journey.

But to go on from that point, if you were then to make another Z3 tube
journey, the bus cap would be replaced by the Z1-4 off-peak cap at £4.90
(assuming all journeys have been off-peak) - so only 90p would be
deducted from the balance. You would then be able to make bus journeys
and tube journeys within Z1-3 without further deduction. NB you would
still have to Touch In and Touch Out - but nothing more would be
deducted.

The cap will always be progressed to the appropriate one as further
journeys are made.

Why are you getting charged for Zones 1-4 when all you have used is the
tube in Zone 3 and the buses? A Zone 2-6 cap of £3.80 will apply in this
case.
