These arent the codes used, as someone else has said only the Central
Line have offical station codes. On other lines, its all down to the
short-hand used.
Often as well the Train Description letter may be different from what
is on the Signal Control Data (M.E.L. or Boxsheets).

Does anyone know where I can get a list of the three-letter station
codes that LU uses to refer to stations? I don't know what the system
is called but I know each station has a code.

The ETA pages at http://www.tfl.gov.uk/tube/travelinfo/eta/ have
the station code for the lines they cover in the URLs.
