Train Tube tickets are valid for all the zones through which travel will
be made, irrespective of the mode used. For example a ticket for a
journey between Selhurst (Zone 4) and Warren Street (Zone 1) will be
issued 'Selhurst to U1234', and is valid for transfer to Underground
services at any interchange on the line of route, i.e. Balham, London
Victoria, or Vauxhall/London Waterloo via Clapham Junction.

But aren't normal LU singles also issued with destinations like U1234?
So could tickets with the same thing printed on them end up having
different validities?

For example, if you go to Ealing Broadway (an NR station) and ask for
a ticket to West Ruislip, you could either get a ticket to U3456 (LU
single costing £3.00, only valid via North Acton), or a ticket to
U3456 (Train Tube single costing £3.40, also valid via South
Greenford).
