After many years of trying and wrangling with ATOC from various people, there now exists a page http://data.atoc.org/fares-data from which you can actually download the fares data without having to shell out £15 or so for the Avantix Traveller CD from TSO, and/or the National Fares Manuals on paper before that.

This is great news at last though, even if it is currently only on a trial basis.  Right, where’s my web browser?
