If a ticket has the "Maltese Cross" on it, indicating that it's valid
for a cross-London transfer by London Underground, DLR or Thameslink
services, the following stations can be used:

Aldgate Farringdon Queens Park
Amersham Finsbury Park Richmond
Baker Street Greenwich Seven Sisters
Balham Highbury & Islington Southwark
Bank Kensington Olympia Stratford
Barking Kentish Town Tottenham Hale
Blackfriars King's Cross/St Pancras Tower Hill
Blackhorse Road Lancaster Gate Upminster
Canning Town Lewisham Vauxhall
Cannon Street Limehouse Victoria
Charing Cross Liverpool Street Walthamstow Central
Ealing Broadway London Bridge Waterloo
Edgware Road Marylebone West Brompton
Elephant & Castle Moorgate West Ham
Embankment New Cross Gate West Hampstead
Euston Old Street Wimbledon
Euston Square Paddington

At least, those are the lists published in Section A of the current
National Fares Manuals. I suspect, however, the Waterloo East is missing
from the "London Terminals" group (given that Old Street and Vauxhall
are there), and New Cross from the cross-London group.

Strange also that the Chiltern Ruislips, and Greenford, aren't on
there. How is one supposed to travel on a Denham to South Greenford
ticket (if one even exists)? The NR journey planner chokes on such a
request - although it's happy to send you on the tube from South
Ruislip to Greenford if you ask it for Denham to Southall.
