One example would be

4 x bus journey between 0700 and 0930 4 x £ 1.00

Then 2 x Z1-5 return on the tube between 0930 and 1900, 2 x £ 3.50

Does Oyster

a) Apply the Peak Day travelcard Z1-5 cap (£ 9.90) or

b) The Off Peak Z1-6 cap (£5.80) plus one day bus pass (£3.00),
total £ 8.80?

For the bus journeys a cap of £3 would be applied after 3 trips. The 4th
is free.

The cap then moves up to £5.80 (off peak cap for journeys Z1-6 using DLR
/ Tube) which means you get 1 bus ride free plus are only charged £2.80
for tube trips valued at £7. Therefore you save £5.20 against the grand
total if each trip was being charged separately.

I'm not convinced by that. If the bus journeys are before 0930, then
surely they wouldn't be covered by an off-peak cap - in which case,
David's scenario "b" of £8.80 would apply as that would be the cheapest
possible combination.

Surely they must be covered by the one day bus pass cap which has no
peak differential? I would agree with your analysis if there was pre
09.30 tube or DLR travel or if there was such a thing as a peak priced
one day bus pass cap.

You cannot trigger a One Day Travelcard related cap if you have only
used a mode which has no zones - there are no bus zones anymore because
of the flat fare nature of the system.

I have gone back through two sets of training material and remain
convinced I am correct.

I think you misunderstood me. The (peak) bus journeys are *not* covered
by an off-peak travelcard cap, but they *are* covered by a one day bus
pass cap. Therefore the cheapest possible fare is the combination of a
one day bus pass cap at £3 for the bus journeys, and an off-peak
travelcard cap at £5.80 for the Tube journeys.

The scenario starts with bus journeys which trigger a cap of £3.00 (not
peak-related). Then, after 0930, a Z1-5 Tube journey is made, valued at
£3.50. However, this cannot trigger an off-peak travelcard cap, because
that cap does not cover bus journeys before 0930 - so the charge-to-date
is £6.50. The subsequent Z1-5 Tube journey should trigger an off-peak
Z1-6 cap for the two Tube journeys, resulting in a total cost of £8.80.

Looking at it the other way, if magnetic tickets were being used for
this scenario, the cheapest combination would be a One Day Bus Pass
(£3.50) plus a Z1-6 Off Peak Day Travelcard (£6.30), totalling £9.80. (A
Peak Day Travelcard would be more expensive, costing £10.40). A Z1-6 Off
Peak Day Travelcard is not valid for *any* travel before 0930, including
buses.
