I've been having a look at the National Fares Manual after someone
posted a URL for it.

I've come across information about "INTERAVAILABILITY OF RAIL/LU
TICKETS ON PARALLEL ROUTES".

See http://www.atoc.org/traveltrade/manu...m/sectionl.pdf

It says -

"Rail Tickets with Validity which includes travel Between -
[snip various routes]
...Seven Sisters/Tottenham Hale/Walthamstow Central and
London Zone U1 or beyond

"Are also Valid by LU/DLR Services Between -
...Seven Sisters/Tottenham Hale/Walthamstow Central and Kings Cross
Undergrd and intermediately"

This *seems* to suggest that a 'one' rail ticket from (e.g.)
Walthamstow Centrtal to Liverpool Street, (which is substantially
cheaper than a zoned U123 ticket) would also be valid on *limited*
LU services - namely anything going to King's Cross, which would only
be possible on the Victoria line.

I guess it's a sort of London Terminals swap, but doesn't seem to
offer any other availability or routing.

Is the ticket 'that is substantially cheaper' actually "London Zone U1" or
"London Terminals"?
