For the Underground NLC Code 0503 is Aldgate East and 0505 is

Which station has or had the NLC Code 0504?
Or was it used for some central ticket office at 55 Broadway, or for
training?

If you can help. thank you very much!


0503 is indeed Aldgate East, but it would appear that 0504 is Alperton
and 0505 is Amersham.

You can download an Excel spreadsheet of all the NLC codes from Joyce
Whitchurch's website here...
