An interesting question is what capacity Oyster has for charging
return fares.

For example, the fares from Harrow & Wealdstone to Watford Junction

CDS £3.50
SDS £3.70
CDR £3.60
SDR £5.30



Oyster has no facility for charging return fares, nor am I aware that
one is planned. I'm not even sure if it can cope with the National
Rail switch between peak and off-peak fares yet - most of these
developments have still to be built into the Oyster system.

If you were silly enough to use Oyster to travel between H&W and WJ in
both directions, you will presumably be charged two single fares (at
least £7, maybe £7.40, instead of £5.30 peak and £3.60 off-peak).

This, of course, is due to different bits of TfL going off in
different directions - Ken and London Rail wanting to grab as many
bits of National Rail as it can as soon as it can, while Fares and
Ticketing is stuck in the LU mould and reluctant to develop Oyster to
cope without overcharging customers.
