Network station design type map

In the TfL London Underground Station Design Idiom guide (http://content.tfl.gov.uk/station-design-idiom-2.pdf) , there’s the wonderful page at section 10.01 that lists the station Design Type from a list of 20 (“Leslie Green” or “New Works (Pre WWII and Post WWII)” for all the tube station.

Is this data-set somewhere online? Could it be made available?
